Dear @Craig Dixon,
Thank you for reaching out. I understand how disruptive this behavior is, especially in a fast‑paced news environment where rapid internal communication is essential.
I have tested this in my test environment, and the Favorites functionality is working as expected. In my tests, a channel can still be added to Favorites using the steps below:
- In Microsoft Teams, locate the channel you want to pin.
- Click the three dots (More options) next to the channel name.
- Select Show in.
- Choose Favorites.
After completing these steps, the channel should appear under the Favorites section for quick access (as shown in the screenshot).

Regarding your issue, may I kindly ask a few questions so I can understand your issue better:
- Does this error occur on desktop, web, or both?
- Could you please confirm which version of Microsoft Teams you are currently using?
- Could you confirm if any changes were made to the Teams policy settings recently, either at the user or organizational level?
- If could, please take a screenshot of the issue you're experiencing so I can better assist you.
In the meantime, please kindly try these troubleshooting steps:
- Microsoft Teams: update to the latest version.
- Sign out and log back in: This will refresh your account linking and may resolve the issue.
- Clear Teams cache: Cached data can sometimes cause problems. Clear the Teams client cache - Microsoft Teams | Microsoft Learn
- Reinstall Teams: If the problem persists, try completely uninstalling and reinstalling it.
Uninstall first: Uninstall Microsoft Teams
Then reinstall: Download Microsoft Teams Desktop and Mobile Apps | Microsoft Team
