Hi @GANESH G,
Thank you for reaching out to the Microsoft Q&A forum.
When a private channel in Microsoft Teams is deleted and later restored, it often takes time for all content to be fully re-indexed, especially if the messages are several months old. As a result, search may not immediately display all restored messages.
Answering your questions:
1. Is this expected behavior after restoring a channel?
Yes, this is normal. After restoring a channel, the search index may not immediately update to include all recovered messages. While you can still view the content by scrolling manually, it may take some time for search to fully catch up.
2. Will Microsoft run a background indexing process on the restored channel?
Yes, Microsoft Teams does perform background indexing after a channel is restored, but it’s not immediate. The process can take several days, depending on factors like content size, environment settings, and overall system load.
3. Is there a way to force the indexing on this channel?
Currently, there’s no way for users or admins to immediately trigger re-indexing of a Microsoft Teams channel. However, you can try a few steps that might help speed up the process:
Option 1: Re-sync the channel
- Leave and rejoin the channel (for members).
- For the owner of the channel, try removing and adding the owner back to the channel. This can sometimes help reset some settings, including indexing.
Option 2: Wait for natural re-indexing
It may take 24–72 hours for the indexing to automatically catch up with all the messages. Make sure that users are still unable to search even after this period.
Option 3: Contact Microsoft Support (for administrator)
If the issue persists after several days, it may indicate an issue with the search index or the restoration process. In that case, you can create a support ticket through Microsoft 365 Admin Center for advanced troubleshooting, as they can perform a deeper re-index or investigate potential backend problems.
