How to Backup Microsoft Teams Chats

Microsoft Teams is widely used by businesses and organizations to communicate through individual chats, group conversations, and team channels. Employees often share important business discussions, meeting details, project updates, files, and other information through Teams chats.

But what happens when you accidentally delete an important conversation, leave an organization, or need to keep a copy of Teams messages for future reference?

This is why backing up Microsoft Teams chats is important. A backup helps you maintain a separate copy of important conversations so you can access them whenever required.

In this guide, I will explain how to backup Microsoft Teams chats using different methods, including Microsoft’s built-in options and a dedicated backup solution. You will also learn which method is suitable for personal users, IT administrators, and businesses.

Why Should You Backup Microsoft Teams Chats?

Before discussing the methods, let’s understand why saving Microsoft Teams conversations is important.

• Prevent Accidental Data Loss: Keep a separate copy of important conversations in case messages are accidentally deleted.

• Maintain Business Records: Save important discussions related to projects, clients, employees, and business operations.

• Meet Compliance Requirements: Organizations may need to preserve communication records for legal, auditing, or regulatory purposes.

• Access Old Conversations: Keep important chat information available for future reference.

• Employee Offboarding: Preserve relevant business conversations when employees leave the organization.

• Data Migration: Maintain important chat records when moving Microsoft Teams data to another Microsoft 365 environment.

Where Are Microsoft Teams Chats Stored?

Microsoft Teams chat messages are stored in Microsoft’s cloud-based services rather than in a regular local folder on your computer.

The storage location depends on the type of conversation:

• One-to-One Chats: Individual chat messages are stored in Exchange Online mailboxes associated with the users.

• Group Chats: Group chat messages are stored in a group chat mailbox.

• Channel Conversations: Channel messages are stored in the Microsoft 365 group mailbox associated with the team.

Files shared in Teams chats and channels are generally stored separately in OneDrive or SharePoint, depending on where they are shared.

Therefore, downloading Teams files does not automatically create a backup of chat messages. You need a method specifically designed to preserve Teams conversations.

Method 1. Save Microsoft Teams Chats Manually

If you only need to preserve a few important messages, you can save them manually. This method is suitable for individual users who want to keep specific conversations for future reference.

Follow these steps:

1. Open the Microsoft Teams desktop application or web version.

2. Navigate to the Chat section from the left-side panel.

3. Open the individual or group conversation you want to save.

4. Find the important messages you want to preserve.

5. Copy the required message content.

6. Open Microsoft Word or Notepad.

7. Paste the copied conversation into the document.

8. Save the document to your computer.

You can also take screenshots of important conversations and save them locally.

Limitations:

• You need to copy messages individually.

• It becomes time-consuming when saving multiple conversations.

• Screenshots do not provide searchable message data.

• This method is not suitable for backing up an entire organization’s Teams data.

Method 2. Backup Microsoft Teams Chats Using Microsoft Graph Export APIs

Microsoft provides Teams Export APIs through Microsoft Graph that allow organizations to export Teams messages programmatically.

Using these APIs, administrators can retrieve:

• One-to-one chat messages.

• Group chat messages.

• Meeting chat messages.

• Channel messages.

This method is useful for organizations that have technical resources and want to build their own Teams message export process.

Steps to Export Microsoft Teams Messages Using Graph API

Step 1. Register an Application

1. Open the Microsoft Entra admin center.

2. Navigate to App registrations.

3. Click New registration.

4. Enter an application name.

5. Select the supported account type.

6. Register the application.

Step 2. Configure API Permissions

1. Open the registered application.

2. Navigate to API Permissions.

3. Select Microsoft Graph.

4. Add the required application permissions.

Some important permissions include:

• Chat.Read.All – Allows access to one-to-one, group, and meeting chat messages.

• ChannelMessage.Read.All – Allows access to channel messages.

• User.Read.All – Allows access to user information.

An administrator must approve the required application permissions.

Step 3. Generate an Access Token

Configure the application authentication process and generate an access token using the appropriate Microsoft identity platform authentication flow.

Step 4. Retrieve Teams Messages

Use the following Microsoft Graph API endpoint to retrieve chat messages:

GET https://graph.microsoft.com/v1.0/users/{id}/chats/getAllMessages

To retrieve channel messages, use:

GET https://graph.microsoft.com/v1.0/teams/{id}/channels/getAllMessages

Replace {id} with the appropriate Microsoft 365 user or Team ID.

Step 5. Save the Exported Data

Process the API response and save the returned message information in your required storage location.

Microsoft Graph returns message information in JSON format, which can be processed using scripts or applications.

Limitations:

• Requires technical knowledge of Microsoft Graph APIs.

• Requires application registration and administrator approval.

• You need to manage authentication, API permissions, and throttling.

• Additional development work may be required to organize and store exported messages.

Method 3. Backup Microsoft Teams Chats Using Microsoft Purview eDiscovery

Microsoft Purview eDiscovery is another option for organizations that need to preserve and export Teams communication data for legal, compliance, auditing, or investigation purposes.

It allows authorized users to search for relevant Teams communication records and export the matching content.

This method is particularly useful for organizations that need to collect conversations related to specific employees, projects, keywords, or date ranges.

Steps to Export Teams Chats Using Microsoft Purview

Step 1. Open Microsoft Purview

1. Visit the Microsoft Purview portal.

2. Sign in using an authorized Microsoft 365 administrator or eDiscovery role account.

3. Navigate to the eDiscovery section.

Step 2. Create an eDiscovery Case

1. Open the eDiscovery workspace.

2. Create a new case.

3. Enter a suitable case name and description.

4. Open the newly created case.

Step 3. Create a Search

1. Navigate to the search section.

2. Create a new search.

3. Select the required data sources.

4. Choose the mailboxes associated with the users whose Teams conversations you want to collect.

5. Add search conditions such as keywords, participants, and date ranges.

Step 4. Run the Search

Run the search and review the matching results. Check whether the required Teams communication records are included.

Step 5. Export the Results

After reviewing the search results, use the available export options to download the collected content.

The exported data can be used for compliance reviews, investigations, and record preservation.

Limitations:

• Requires appropriate Microsoft Purview licensing and permissions, depending on the features used.

• The process can be complicated for users who are unfamiliar with eDiscovery.

• It is primarily designed for compliance and investigation requirements rather than routine backup.

• Users need to configure searches and review the exported results.
