Known issues for Microsoft Teams

This article lists the known issues for Microsoft Teams, by feature area.

Administration

Issue title Behavior / Symptom Known workaround Discovery date
Audit logs may report an incorrect username as initiator when someone has been removed from a Team
Teams team is a modern group in AAD. When you add/remove a member through the Teams user interface, the flow knows exactly which user initiated the change, and the Audit log reflects the correct info. However, if a user adds/removes a member through AAD, the change is synced to the Teams backend without telling Teams who initiated the action. Microsoft Teams picks the first owner of team as the initiator, which is eventually reflected in the Audit log as well.

  1. Under Internet Options > Privacy > Advanced, accept First-Party and Third-Party cookies, and check the box for Always allow session cookies.
  2. Click Internet Options > Trusted Sites > Sites, and add all of the following:
    • https://\login.microsoftonline.com

If the user logs out of Teams and restarts the machine, upon restart, Teams will automatically log in using the domain-joined profile.

Tabs not working since Conditional Access was enabled
Some tabs may not load anymore in the Desktop Client since Conditional Access was enabled on the tenant. The tabs load when using the Web Client. Some tabs that might be affected are: PowerBI, Forms, VSTS, PowerApps, and SharePoint List.

We are working with partners to enable these scenarios; so far we have enabled Planner, OneNote, and Stream.
