Locating documents and sharing them with others within Microsoft Teams channels or chats
The described behavior matches known issues where file or folder changes in a backing library do not immediately appear in the UI and only show up after a manual refresh or navigation change.
In Microsoft Teams, channel files are stored in the associated SharePoint document library. If the underlying folder or library view is slow to update, or if the folder has been renamed, deleted, or is temporarily unsynced, the Teams UI can show an empty or outdated list until it re-queries the library.
For channels, verify the associated SharePoint folder is healthy and correctly named:
- In Teams, go to the affected team and channel.
- Open the channel’s files in SharePoint:
- In some experiences: Teams → select the channel → Shared > More commands > Open in SharePoint.
- In others: under Chat → Channels → select the channel → Shared > More commands > Open in SharePoint.
- In SharePoint, open the Details pane and check Activity for:
- Folder renamed from its original channel name.
- Folder deleted or moved.
- If the folder was renamed, rename it back to the original channel folder name from the Activity history.
- If the folder is present and correct, go back to Teams and use the channel’s Shared or Files tab and select Sync to resync the folder.
If the issue is intermittent and resolves when switching channels, it is likely a UI refresh or sync delay rather than a permanent data issue. In that case, confirming the SharePoint folder name and using Sync on the channel’s files tab are the primary supported steps from current guidance.
If the problem persists across multiple channels and users, collect details (tenant, affected teams/channels, timestamps, and client type) and open a support request through Microsoft 365 support so logs can be reviewed.
