How Should Large Companies Implement Litigation Holds Across Email, Teams, Slack, and Mobile Devices? Florida, North Carolina, and Federal Litigation Guide

Large companies should implement litigation holds by identifying the dispute, preserving relevant custodians and data sources, suspending routine deletion where necessary, documenting each preservation step, and coordinating legal, IT, compliance, HR, records, and business teams. A modern litigation hold cannot stop at email; it should address Microsoft Teams, Slack, text messages, mobile devices, cloud storage, collaboration tools, shared drives, and third-party systems that may contain relevant evidence.

The goal is not perfection. The goal is a defensible, timely, reasonable preservation process that can withstand discovery, sanctions motions, injunction hearings, summary judgment, trial, and appeal.

The answer depends on several factors

How a large company should implement a litigation hold depends on:

1. Whether litigation is pending, threatened, reasonably anticipated, or already filed

2. Whether the matter is in Florida state court, North Carolina state court, federal court, arbitration, regulatory proceedings, or appellate litigation

3. Whether the dispute involves business litigation, contract claims, fraud, employment-adjacent issues, trade secrets, unfair competition, fiduciary duties, regulatory investigations, injunctions, or asset preservation

4. Which systems store potentially relevant evidence

5. Whether relevant data lives in email, Microsoft Teams, Slack, mobile phones, text messages, iMessage, WhatsApp, Signal, Google Workspace, SharePoint, OneDrive, shared drives, CRM systems, accounting systems, ticketing tools, or cloud apps

6. Whether the company uses automatic deletion, retention policies, ephemeral messaging, auto-archiving, device wipes, or data minimization programs

7. Whether employees use company devices, personal devices, BYOD programs, or unmanaged messaging apps

8. Whether departing employees, executives, sales teams, engineers, finance personnel, IT admins, HR personnel, or third-party vendors are custodians

9. Whether trade secrets, customer data, financial records, source code, privileged communications, or confidential board materials are involved

10. Whether the company needs forensic preservation, targeted collection, legal-hold software, Microsoft Purview, Slack legal holds, Google Vault, MDM tools, or outside e-discovery support

11. Whether the company needs emergency injunction evidence, protective orders, sealing, or expedited discovery

12. Whether preservation failures could create sanctions, adverse inference, evidence exclusion, default risk, settlement pressure, or appeal issues

Large-company litigation holds require governance. A single email from legal may not be enough if IT systems continue deleting relevant data.

What is a litigation hold?

A litigation hold is a process used to preserve documents, electronically stored information, and physical evidence that may be relevant to a dispute.

A litigation hold usually includes:

• Written notice to custodians

• Identification of relevant data sources

• Suspension of routine deletion where necessary

• Preservation of emails and attachments

• Preservation of chat messages

• Preservation of mobile device data

• Preservation of cloud files and shared drives

• Preservation of business-system records

• Tracking custodian acknowledgments

• Follow-up reminders

• Documentation of preservation steps

• Periodic updates as the dispute evolves

• Release of the hold when appropriate

For a large company, the hold should be both a legal instruction and a technical preservation workflow.

When does the duty to preserve begin?

A company should begin preservation when litigation is reasonably anticipated, not only after a complaint is served.

Triggers may include:

• Demand letter

• Preservation letter

• Threatened lawsuit

• Filed complaint

• Government inquiry

• Regulatory subpoena

• Civil subpoena

• Internal investigation likely to lead to litigation

• Contract default notice

• Employee complaint likely to become a claim

• Trade secret or data theft concern

• Customer dispute escalating toward litigation

• Termination of a major business relationship

• Board-level dispute

• Asset-transfer concern

• Emergency injunction threat

• Notice of appeal or post-judgment enforcement risk

Waiting for formal service can be too late, especially if retention policies delete chat messages, texts, logs, or mobile data quickly.

Why email-only holds are no longer enough

Email is still important, but many business decisions now happen outside email.

Relevant evidence may be found in:

• Microsoft Teams chats

• Teams channels

• Slack channels

• Slack direct messages

• Slack group messages

• Text messages

• iMessages

• Android messages

• WhatsApp

• Signal

• Zoom chat

• Google Chat

• SharePoint

• OneDrive

• Google Drive

• CRM notes

• Salesforce

• HubSpot

• Jira

• Asana

• Monday.com

• ServiceNow

• GitHub

• Source code repositories

• Accounting systems

• ERP systems

• HRIS systems

• Expense platforms

• Cloud logs

• Security logs

• Access logs

• Mobile-device backups

Large companies should treat the litigation hold as a data-map exercise, not just a custodian-email exercise.

Step 1: Identify the dispute and preservation scope

The hold should begin with a clear definition of the dispute.

Legal should identify:

• Parties

• Claims or likely claims

• Defenses

• Relevant time period

• Relevant business units

• Key events

• Key contracts

• Key projects

• Key transactions

• Key communications

• Potential damages

• Potential injunction issues

• Potential custodians

• Potential data sources

A hold that is too narrow may miss critical evidence. A hold that is too broad may create unnecessary cost, disruption, privacy issues, and over-preservation.

Step 2: Identify custodians

Custodians are people who may have relevant information.

For large companies, custodians may include:

• Executives

• General counsel

• In-house lawyers

• Business-unit leaders

• Sales personnel

• Account managers

• Finance personnel

• HR personnel

• IT administrators

• Product managers

• Engineers

• Project managers

• Customer-success teams

• Operations personnel

• Compliance personnel

• Board members

• Former employees

• Contractors

• Consultants

• Outside vendors

• Shared mailbox owners

• System administrators

• Records custodians

Custodian identification should be iterative. The first list may change after interviews, system searches, document review, or discovery requests.

Step 3: Identify data sources

A defensible hold should identify both custodian-based and system-based data.

Potential data sources include:

• Exchange or Gmail mailboxes

• Email archives

• Microsoft Teams chats and channels

• Slack workspaces and channels

• Google Chat

• SharePoint

• OneDrive

• Google Drive

• Network drives

• Local hard drives

• Mobile phones

• Tablets

• Laptops

• Personal devices used for work

• SMS and MMS

• iMessage

• WhatsApp and Signal

• CRM systems

• Accounting systems

• ERP systems

• HR systems

• Ticketing systems

• Project-management tools

• Code repositories

• Cloud storage

• Security logs

• Access logs

• Backup systems

• Voicemail

• Call recordings

• Video meeting transcripts

• Meeting chats

• Social media accounts

• Website administration records

• Third-party vendor systems

The company should document why each source is or is not included.

Step 4: Suspend deletion and auto-retention where needed

Large companies often use automatic deletion policies for information governance, privacy, storage control, and regulatory compliance. Once a litigation hold applies, those policies may need exceptions.

Preservation may require suspending or adjusting:

• Email deletion rules

• Chat retention limits

• Slack retention settings

• Teams retention settings

• Mobile message deletion

• Device wipe policies

• Departing employee mailbox deletion

• Account deactivation workflows

• Auto-purge rules

• Backup rotation policies where backups are uniquely relevant

• Log deletion schedules

• Ephemeral messaging settings

• Auto-archive rules

• Shared drive cleanup

• CRM record deletion

• Cloud lifecycle rules

• Source-code repository retention

• Ticketing-system retention

• Security log retention

This is where legal and IT must work together. Custodians may receive hold notices, but preservation can still fail if system-level deletion continues.

Step 5: Preserve email correctly

Email preservation should address:

• Active mailboxes

• Archived mailboxes

• Shared mailboxes

• Distribution lists

• Attachments

• Calendar entries

• Deleted items

• Recoverable items

• Journaled mail

• Litigation hold or retention hold features

• Departing employee mailboxes

• Executive assistants and delegated mailboxes

• Third-party email archives

• Email encryption tools

• External messages

• Privileged communications

• Auto-forwarding rules

Email is usually easier to preserve than chat or mobile data, but mistakes still happen when employees leave, mailboxes are converted, or retention rules continue to purge data.

Step 6: Preserve Microsoft Teams data

Teams preservation requires understanding where Teams content lives.

Large companies should consider:

• 1:1 chats

• Group chats

• Channel messages

• Private channels

• Shared channels

• Meeting chats

• Meeting recordings

• Transcripts

• Files shared in Teams

• SharePoint locations

• OneDrive locations

• Reactions and edits where available

• Attachments

• External guest communications

• Deleted messages

• Retention policies

• Export and review tools

• Custodian mapping

Legal should not assume that preserving Exchange mailboxes automatically captures every Teams artifact needed for litigation. Teams data may require specific e-discovery searches and preservation procedures.

Step 7: Preserve Slack data

Slack preservation can be complicated because retention, export, and legal-hold functionality may depend on the company’s Slack plan and configuration.

Large companies should consider:

• Public channels

• Private channels

• Direct messages

• Group direct messages

• Multi-workspace channels

• Shared channels

• External Connect channels

• Files shared in Slack

• Edits

• Deletions

• Reactions

• Threads

• User status information where relevant

• App integrations

• Links to Google Drive, OneDrive, Jira, GitHub, or other systems

• Retention settings

• Enterprise Grid legal hold options

• Export availability

• Deactivated users

• Guest accounts

• Bots and workflow messages

• Third-party Slack archiving or e-discovery tools

Slack messages can be highly relevant because business teams often use Slack for fast, informal decision-making. A defensible hold should treat Slack like discoverable business communication, not casual conversation outside the case.

Step 8: Preserve mobile device data

Mobile devices are often the weakest part of a litigation hold.

Large companies should consider:

• Company-issued phones

• BYOD devices

• Executive phones

• Sales-team phones

• Field-employee phones

• Text messages

• iMessages

• Android messages

• WhatsApp

• Signal

• Telegram

• Photos and videos

• Call logs

• Voicemail

• Location data where relevant and lawful

• Mobile email

• Mobile Teams and Slack apps

• App-specific attachments

• Screenshots

• Device backups

• MDM controls

• Remote wipe policies

• Device replacement schedules

• Employee departure procedures

The company should not rely only on custodian self-collection for mobile data in high-risk matters.

Forensic or managed collection may be needed.

Step 9: Address BYOD and personal devices

Bring-your-own-device programs create difficult preservation issues.

The company should ask:

• Do employees use personal phones for company work?

• Are business texts sent from personal numbers?

• Are Teams or Slack apps installed on personal devices?

• Are messages stored locally or in the cloud?

• Does the company’s BYOD policy permit access or preservation?

• Does the company have consent to collect business data?

• Are privacy laws or employment laws implicated?

• Are former employees involved?

• Is targeted collection possible?

• Is forensic imaging proportional?

• Is custodian certification sufficient?

• Is court guidance needed?

BYOD preservation requires balancing litigation obligations, privacy, proportionality, and technical feasibility.

Step 10: Issue a clear written hold notice

A litigation hold notice should be clear, practical, and tailored.

It should identify:

• The matter

• The reason for the hold

• The relevant time period

• The types of documents and ESI to preserve

• Specific platforms covered

• Email preservation obligations

• Teams preservation obligations

• Slack preservation obligations

• Mobile-device obligations

• Text-message obligations

• Cloud storage obligations

• Instructions not to delete, modify, overwrite, or destroy

• Who to contact with questions

• Requirement to acknowledge receipt

• Requirement to identify additional data sources

• Requirement to preserve personal-device work communications where applicable

• Warning not to use ephemeral or disappearing-message settings for relevant communications

• Instruction to notify legal before device replacement, account deletion, or employment departure

• Reminder that the hold remains in effect until released

The notice should be understandable to business employees, not just lawyers.

Step 11: Track acknowledgments and compliance

A large-company litigation hold should be tracked.

Legal should document:

• Who received the hold

• When it was sent

• Whether the custodian acknowledged

• Who failed to acknowledge

• Follow-up reminders

• Custodian questions

• Additional sources identified

• Departing employee status

• Hold modifications

• Releases

• IT preservation steps

• Collection steps

• Exceptions

• Escalations

If preservation is later challenged, the company should be able to show what it did and when.

Step 12: Coordinate with IT and legal operations

IT and legal operations are central to modern preservation.

They may need to:

• Place mailboxes on hold

• Preserve Teams content

• Preserve Slack content

• Suspend deletion policies

• Preserve cloud files

• Preserve logs

• Preserve accounts of departing employees

• Prevent remote wipes

• Preserve mobile devices

• Coordinate forensic collection

• Document technical steps

• Maintain chain of custody

• Coordinate with e-discovery vendors

• Apply access controls

• Support privilege and confidentiality workflows

• Track retention exceptions

Legal should not assume IT knows which legal obligations matter. IT should not assume legal understands all deletion workflows. The hold process should bridge that gap.

Step 13: Interview key custodians

Custodian interviews can reveal data sources that legal and IT would otherwise miss.

Ask custodians:

• What platforms did you use for this project?

• Did you communicate by text?

• Did you use personal devices?

• Did you use Slack, Teams, WhatsApp, Signal, or other apps?

• Did you share files through links?

• Did you use shared drives?

• Did you store documents locally?

• Did you use personal email?

• Are there external collaborators?

• Are there former employees with relevant data?

• Did any relevant data get deleted, archived, or migrated?

• Are there code repositories, ticketing tools, CRM records, or financial systems involved?

Large companies often discover critical evidence sources only after talking to the people who actually did the work.

Step 14: Preserve departing employee data

Departing employees are high-risk custodians.

Before account closure, device wipe, or laptop reissue, the company should determine whether the employee is subject to a hold.

Preserve:

• Email mailbox

• Teams data

• Slack data

• OneDrive or Google Drive

• Laptop

• Desktop

• Mobile device

• Text messages

• Local files

• CRM records

• Source code access

• External storage devices

• Personal device work communications if covered

• Voicemail

• Calendar

• Expense records

• Badge or access logs where relevant

HR, IT, and legal should have an exit process that checks active litigation holds before deleting or wiping accounts and devices.

Step 15: Document collection decisions

Preservation and collection are related but not identical.

The company may preserve broadly but collect more narrowly. Collection decisions should be documented.

For each source, record:

• Whether it was preserved

• Whether it was collected

• Who collected it

• When it was collected

• What tool was used

• What filters were applied

• What date range was used

• What custodians were included

• Whether metadata was preserved

• Whether chain of custody was maintained

• Whether any data was inaccessible

• Whether any data was lost

• Whether restoration was attempted

• Whether opposing counsel was notified if required

Documentation is often what makes a hold defensible.

Step 16: Update the hold as the case changes

A litigation hold is not one-and-done.

Update the hold when:

• New claims are added

• New parties are added

• Counterclaims are filed

• Injunction issues arise

• Discovery requests identify new sources

• Custodian interviews reveal new data

• Employees leave

• Systems migrate

• Retention policies change

• The relevant time period expands

• The company discovers data loss

• A court order changes obligations

• The case settles in part

• Appeal begins

• Remand occurs

• The hold can be released

Legal should periodically confirm that the hold still fits the case.

Step 17: Release the hold properly

When the duty to preserve ends, the hold should be released deliberately.

Before release, confirm:

• The matter is fully resolved

• Appeal deadlines are expired or resolved

• Settlement obligations are complete

• No related litigation remains

• No regulatory inquiry remains

• No indemnity or insurance issue requires preservation

• No preservation order remains

• No internal investigation requires continued preservation

• No related hold applies to the same data

A release notice should tell custodians and IT what is no longer subject to hold and what retention policies may resume.

Special issue: litigation holds and emergency injunctions

Emergency injunction cases require faster preservation.

If a company may seek or oppose a temporary restraining order or preliminary injunction, preserve evidence immediately.

Relevant emergency evidence may include:

• Texts

• Teams messages

• Slack messages

• customer communications

• access logs

• download logs

• security logs

• asset-transfer records

• bank records

• source code repositories

• CRM data

• confidential file access

• device activity

• screenshots

• emails

• witness declarations

• forensic images

Emergency relief depends on evidence. The company should preserve and collect enough to prove or oppose irreparable harm quickly.

Special issue: legal holds and mobile messaging apps

Mobile messaging apps create preservation risk because messages may be encrypted, ephemeral, device-specific, or outside central company systems.

Companies should address:

• SMS

• iMessage

• WhatsApp

• Signal

• Telegram

• WeChat

• Messenger

• App-specific file sharing

• Disappearing messages

• Employee personal accounts

• Group chats

• Executive communications

• International data issues

• Device replacement

• Cloud backups

• MDM limitations

If employees use mobile apps for business, the litigation hold should say so expressly.

Special issue: ephemeral messaging

Ephemeral messaging can create serious preservation issues if messages disappear after a short period.

Companies should evaluate:

• Whether ephemeral messaging is allowed for business

• Whether auto-delete settings apply

• Whether the settings can be suspended

• Whether custodians have relevant ephemeral communications

• Whether policies prohibit using ephemeral messaging for legal matters

• Whether alternative records exist

• Whether forensic recovery is possible

• Whether court disclosure is needed if relevant messages were lost

A company should not allow disappearing messages to continue for relevant communications after a preservation duty attaches.

Special issue: third-party systems and vendors

Large companies often rely on third-party vendors for business-critical data.

Relevant data may be held by:

• Cloud providers

• Managed IT vendors

• CRM vendors

• HRIS vendors

• payroll providers

• accounting platforms

• e-discovery vendors

• security vendors

• call-center vendors

• marketing platforms

• payment processors

• logistics providers

• data warehouses

• external consultants

• outside accountants

• law firms

• insurers

The company should determine whether it has possession, custody, or control, contractual access rights, export rights, or preservation obligations for third-party data.

Practical framework: implementing a large-company litigation hold

1. Trigger review

Decide whether litigation is reasonably anticipated.

2. Legal scoping

Define claims, defenses, time period, custodians, data sources, and business units.

3. Hold notice

Issue a clear written notice tailored to the matter.

4. IT preservation

Suspend deletion or place technical holds where needed.

5. Custodian acknowledgment

Track acknowledgments and follow up.

6. Data map

Identify email, Teams, Slack, mobile, cloud, file-share, business-system, and third-party data.

7. Interview custodians

Find informal, mobile, and project-specific sources.

8. Preserve high-risk sources

Prioritize short-retention and volatile sources such as chats, texts, logs, mobile devices, and departing employee accounts.

9. Document steps

Create a defensibility record.

10. Collect when appropriate

Collect targeted data using defensible methods.

11. Supplement and monitor

Update the hold as facts, claims, parties, and systems change.

12. Release carefully

Release only when preservation obligations are truly complete.

Deadlines matter

Large companies should track preservation deadlines tied to:

• Demand letters

• Preservation letters

• Complaint service

• Subpoenas

• TRO or injunction hearings

• Rule 26(f) conference

• Rule 26 initial disclosures

• Discovery requests

• ESI protocol deadlines

• Protective order deadlines

• Employee departures

• Device replacement cycles

• Retention-policy deletion dates

• Account deactivation dates

• System migration dates

• Backup overwrite dates

• Expert disclosure deadlines

• Summary judgment deadlines

• Trial deadlines

• Appeal deadlines

• Remand deadlines

• Settlement preservation obligations

Preservation often fails because legal deadlines and IT deletion cycles are not aligned.

Risks of a weak litigation hold

A weak litigation hold can create risks such as:

• Lost evidence

• Sanctions

• Adverse inference

• Evidence exclusion

• Monetary sanctions

• Discovery orders

• Reopened discovery

• Forensic inspection

• Default or dismissal in extreme cases

• Loss of settlement leverage

• Harm to credibility

• Increased e-discovery cost

• Privilege complications

• Injunction problems

• Appeal problems

• Board or executive scrutiny

• Regulatory exposure

The risk is not only legal. A preservation failure can become a business and reputational problem.

Risks of over-preservation

Over-preservation can also create problems.

Risks include:

• Excessive storage cost

• Business disruption

• Privacy concerns

• Security risk

• Unnecessary review burden

• Overbroad collection

• Employee confusion

• Conflicts with data minimization policies

• Regulatory retention conflicts

• Increased production volume

• Higher privilege review cost

A strong hold is reasonable, targeted, and documented.

Evidence considerations

Preserve evidence in native or defensible form when possible.

Evidence may include:

• Emails and attachments

• Teams chats and files

• Slack channels, DMs, files, and metadata

• Text messages

• Mobile app messages

• Cloud documents

• Shared drive files

• Local files

• Spreadsheets

• PDFs

• CRM entries

• Accounting records

• ERP exports

• HR records

• Audit logs

• Access logs

• Download logs

• Security logs

• Source code

• Tickets

• Meeting recordings

• Transcripts

• Calendar entries

• Voicemail

• Photos and videos

• Device backups

• Metadata

• System reports

Screenshots may be useful for quick review, but they may not preserve metadata, completeness, or chain of custody.

Forum considerations

Federal court

Federal court preservation issues often focus on Rule 26 discovery planning, Rule 37(e) sanctions for lost ESI, Rule 45 subpoenas, Rule 26(c) protective orders, Rule 16 scheduling orders, ESI protocols, and proportionality.

Florida state court

Florida litigation holds should account for Florida discovery obligations, spoliation principles, injunction practice, civil procedure rules, and appeal preservation. Businesses litigating in Florida should preserve ESI before routine deletion or device changes undermine the record.

North Carolina state court

North Carolina litigation holds should account for North Carolina discovery rules, court orders, Business Court or complex business disputes where applicable, injunction proceedings, and preservation obligations. Companies should preserve mobile, chat, and collaboration data when relevant to claims or defenses.

Arbitration

Arbitration does not eliminate preservation obligations. Arbitration clauses, provider rules, emergency arbitrator procedures, and document exchange protocols may require preservation of the same ESI that would matter in court.

Regulatory or internal investigations

Litigation holds may overlap with government inquiries, regulatory subpoenas, internal investigations, audit obligations, and employment investigations. Coordination matters because one investigation may trigger preservation for another proceeding.

Appeal consequences

Preservation failures can affect appeals.

Appeal-sensitive issues may include:

• Whether ESI should have been preserved

• Whether the company took reasonable steps

• Whether lost information can be restored or replaced

• Whether prejudice existed

• Whether intent to deprive was proven

• Whether sanctions were proportionate

• Whether the trial court excluded evidence

• Whether a jury instruction was proper

• Whether summary judgment was affected

• Whether an injunction record was incomplete

• Whether discovery rulings were preserved

• Whether harmless error applies

• Whether the record supports the sanction or denial of sanctions

An appellate-aware litigation hold creates a record showing reasonable, timely, documented preservation.

Common mistakes

Common mistakes include:

• Waiting for a complaint before preserving

• Sending a generic hold notice only to executives

• Preserving email but not Teams or Slack

• Ignoring mobile devices

• Ignoring BYOD communications

• Ignoring departing employees

• Failing to suspend deletion policies

• Assuming backups solve preservation

• Ignoring ephemeral messages

• Letting IT wipe devices under normal procedures

• Failing to track acknowledgments

• Failing to interview custodians

• Failing to preserve metadata

• Relying on screenshots only

• Forgetting third-party systems

• Failing to update the hold

• Releasing the hold before appeal deadlines expire

• Failing to document preservation decisions

• Treating legal hold as an IT-only task

Large-company preservation is cross-functional. Legal, IT, HR, compliance, records, security, and business leaders all may have roles.

Authority and legal framework

Federal Rule of Civil Procedure 26 requires early disclosure and discovery planning and treats electronically stored information as part of civil discovery. Rule 26(f) discovery planning may require parties to address preservation, ESI, privilege, and discovery procedure early in the case. Rule 26(c) also allows protective orders for sensitive information.

Federal Rule of Civil Procedure 37(e) addresses failure to preserve electronically stored information. If ESI that should have been preserved is lost because a party failed to take reasonable steps, and the information cannot be restored or replaced through additional discovery, the court may order curative measures upon a finding of prejudice. More severe measures, including adverse presumptions, adverse-inference instructions, dismissal, or default judgment, require a finding that the party acted with intent to deprive another party of the information’s use in litigation.

Federal Rule of Civil Procedure 45 can affect preservation and production of third-party records. Federal Rule of Civil Procedure 16 allows courts to manage discovery, schedules, preservation issues, and case management obligations.

Microsoft, Slack, and Google each provide enterprise tools and documentation relevant to preservation and e-discovery. But legal obligations are not satisfied by simply having tools available. The company must understand how its systems are configured, how retention operates, what custodians use, and whether the preservation steps actually captured relevant data.

These authorities show why large companies should implement litigation holds through a documented legal and technical workflow rather than relying on informal instructions.

Frequently Asked Questions

How should large companies implement litigation holds across email, Teams, Slack, and mobile devices?

Large companies should identify the dispute, custodians, systems, and relevant time period; issue a written hold; suspend deletion where needed; preserve email, Teams, Slack, mobile, cloud, and business-system data; track acknowledgments; coordinate with IT; and document each step.

When does a company need to issue a litigation hold?

A company should issue a litigation hold when litigation is reasonably anticipated, threatened, pending, or triggered by a demand letter, subpoena, preservation letter, injunction threat, government inquiry, or serious business dispute.

Is preserving email enough?

No. Relevant evidence may exist in Microsoft Teams, Slack, texts, iMessages, mobile apps, cloud storage, shared drives, CRM systems, accounting systems, project tools, and third-party platforms.

How should companies preserve Slack messages?

Companies should identify relevant Slack workspaces, channels, direct messages, shared channels, files, retention settings, custodians, and export or legal-hold options. Slack preservation depends on the company’s plan, configuration, and available tools.

How should companies preserve Microsoft Teams data?

Companies should identify relevant chats, channels, meeting chats, shared files, private channels, shared channels, recordings, transcripts, OneDrive, SharePoint, and retention settings. Teams preservation usually requires coordination with Microsoft 365 e-discovery tools and IT administrators.

Do litigation holds apply to mobile phones?

Yes, when mobile devices contain relevant business communications or data. Text messages, iMessages, WhatsApp, Signal, photos, videos, call logs, and mobile app communications may need preservation depending on the dispute.

What happens if ESI is lost after a duty to preserve begins?

In federal court, Rule 37(e) may allow curative measures if lost ESI should have been preserved, reasonable steps were not taken, the information cannot be restored or replaced, and prejudice results. Severe sanctions require intent to deprive.

Does Biazzo Law help large companies implement litigation holds?

Yes. Biazzo Law helps businesses and general counsel evaluate litigation hold triggers, ESI preservation, Teams and Slack data, mobile device evidence, Rule 26 discovery planning, protective orders, sanctions risk, emergency injunction evidence, and appellate preservation in Florida, North Carolina, and federal litigation.
