To export Teams chat and channel messages, you can use the Teams data export tool or the Teams Export APIs. The Teams data export tool allows you to export the following data:
- 1:1 chats
- Group chats
- Meeting chats
- Channel messages
You can initiate the export directly from the Teams admin center, and it supports exporting the structure of teams and channels, user rosters, and installed apps as well. However, it's important to note that any new data created during or after the export will not be included, so you may need to perform another export within 90 days to capture that data.
For ongoing data consumption and reporting, you can set up a recurring data connection using the Teams Export APIs. These APIs allow you to programmatically access and export messages, including direct messages, group messages, and channel posts. However, please be aware that some of these APIs may be metered and could incur costs.
To summarize:
- Exporting Data: Use the Teams data export tool or the Teams Export APIs.
- Recurring Data Feed: Set up using the Teams Export APIs for ongoing access to channel messages.
For more detailed steps on accessing these tools, refer to the documentation provided by Microsoft.
