Teams admin policy change removes custom backgrounds for users

Scenario

Users lose access to custom backgrounds after a Teams or policy change, causing confusion during meetings.

Recommended Resolution Path

1. Check Teams meeting policy settings related to video filters and effects.
2. Confirm whether the issue is tenant-wide or scoped to one policy group.
3. Test on web and desktop clients to isolate policy from local cache.
4. Document the intended meeting policy so future changes do not surprise users.

Technician Notes

Confirm the result, document the root cause, and record any preventative action worth standardizing.
