How to Recover Deleted Messages From Microsoft Teams

Microsoft Teams is essential for workplace communication across UK businesses, so losing important chat messages can potentially have a severe impact. If a message or conversation has been deleted, whether accidentally or deliberately, it’s important that you know how to get it back.

This guide clarifies what happens when you delete messages in Teams and gives you the steps that you can take as a user or an admin to get them back, with tips on safeguarding your Teams data moving forward.

What Happens When You Delete Messages in Microsoft Teams?

Before we go into how you can recover deleted messages, it makes sense first to give an overview on exactly what happens when messages are deleted in Teams, as this can affect how you go about getting your messages back.

Deleting messages in Teams comes with two possibilities: deleting them for your view, or the more severe case of deleting them for everyone. However, regardless of which method you choose, deleted messages are not immediately erased from Microsoft’s backend systems.

Instead, Teams flags the messages for deletion and then stores the data within the Exchange Online mailboxes associated with each participant, compliant with your organisation’s retention policies. This means that while you lose direct access, the messages still exist for a period, allowing recovery efforts by authorised administrators.

Deleted messages do not have their own “Recycle Bin” within Teams, so once the brief “Undo” option disappears, normal users cannot reverse the deletion themselves.

Can Microsoft Teams Users Recover Deleted Messages?

Unfortunately, most Teams users cannot recover deleted messages once they have missed the “Undo” window that lasts for 5-10 seconds after a message is deleted.

Once this window closes, users cannot retrieve deleted messages within Teams. No self-restore feature exists for past deletions, so if important messages are lost then reaching out to your IT team promptly is the next best step for recovery possibilities.

Can IT Administrators Recover Deleted Teams Messages?

IT administrators with the right permissions can use Microsoft 365’s Compliance Center tools to recover deleted Teams messages. They can’t be recovered back into the chat interface, so they will have to be extracted in formats like PST files, which can be reviewed in Outlook or shared as evidence.

Admins with the correct privileges can recover deleted Teams messages through one of two ways:

• Content Search: Admins can create a search query filtered by user mailboxes and dates to locate deleted chat messages stored within Exchange Online. Once found, these messages can be previewed and exported.
• eDiscovery Tool: For more extensive or legal compliance recoveries, the eDiscovery Core or Advanced features allow admins to archive, search, and export Teams messages held due to retention policies or legal holds.

How Long Do Deleted Messages Stay Recoverable in Microsoft Teams?

The ability to recover deleted Teams messages largely depends on your organisation’s Microsoft 365 retention policies. Without a retention policy, deleted messages may only be recoverable for a short time, often 30 days or less.

Organisations using Microsoft 365 Business or Enterprise licenses can configure retention policies that preserve message data for months or years, safeguarding crucial communications against permanent deletion.

If no retention or legal hold was applied before deletion, messages may be unrecoverable using native tools after the retention window closes.

How to Recover Deleted Teams Channels and Teams

Deleted Teams channels and entire teams can often be restored within 30 days of deletion by team owners or global admins:

• Channels: Go to the Teams app > Manage Team > Channels tab > Deleted channels list. Channels can be restored along with messages if within the time limit.
• Teams: Deleted teams can be recovered from the Microsoft 365 Admin Center under Deleted Groups within the 30-day window.

Beyond 30 days, recovery gets more challenging and might require manual re-creation alongside eDiscovery searches, reinforcing the importance of regular Microsoft Teams cloud backups.

What About Recovering Deleted Files Shared in Teams?

Files shared in chats or channels follow different storage and recovery paths, but are ultimately more recoverable than just messages.

Files in chats are stored in the sharer’s OneDrive for Business, where they can be restored from the recycle bin for up to 93 days.

Channel files live in the team’s SharePoint site and likewise can be recovered from the SharePoint recycle bin during the retention period.

After the retention or recycle bin period expires, files are permanently deleted unless held under compliance policies.

How to Set Up Retention Policies to Prevent Data Loss in Teams

Setting an effective retention policy through the Microsoft Purview Compliance Portal helps ensure your Teams messages and files are preserved long-term. You can define retention periods, specify which users or teams are covered, and apply legal holds to prevent premature deletion.

Retention policies form the foundation for any future recovery efforts so it is crucial that they are set up properly from the outset. Without them, once messages are deleted and retention expires, recovery is unlikely.

Why Backup Solutions Are Essential for Microsoft Teams Data Protection

Microsoft’s native retention and recovery capabilities, while useful, have important limitations. Recovery can be complex and technical for admins, and they have time restrictions that can hinder recovery methods.

Third-party cloud backup services designed for Microsoft 365 can continuously back up Teams data including chats, files, teams, and channels. These offer:

• Unlimited retention beyond native limits
• Easier and faster granular recovery without relying solely on compliance tools
• Protection against accidental deletion, ransomware, and extended data loss scenarios

For businesses serious about continuity and compliance, investing in a reliable Microsoft Teams backup service ensures peace of mind.
