My Microsoft Teams tabs are missing yet they are still accessible on different devices?

Follow this procedure to troubleshoot:

1. Please confirm with other members and make sure they didn’t accidentally remove these tabs, and also check Team settings to see if members in each impacted team group have the permission to create and delete tabs:

2. Check Office 365 audit log (you may contact admin to help you as this feature needs Office 365 admin permissions) to see if there are any relevant events being recorded.

3. Please check Teams client app updates to make sure it’s the latest version. If these tabs were added by you and if it is convenient, let other members add these tabs via Teams web app and monitor for a while to see if the issue would appear again.

I hope this helps!

Hi Ross,

Based on the description “Microsoft Teams tabs are missing yet they are still accessible on different devices”, issue most likely to client side. May I know whether this issue happen on both using Teams desktop and Teams web client on your device?

If you are using Teams desktop client, please use the Teams web client to check this issue.

Does this issue happen with every channels or specific Teams channel?
