Has there been an update to the dimensions of the teams backgrounds? March 13, 2025

This must be some kind of bug after a recent update. I have simlar backgrounds that were already added, with the same resolution working fine. I just can't add any new ones. This would lead me to believe it is not intended and MS needs to patch/fix.

A number of my colleagues have faced this issue, and I’ve just found a solution:

1. On a device where the images have successfully uploaded, navigate to the following directory:
   ...*Microsoft\MSTeams\Backgrounds\Uploads*
2. Inside the Uploads folder, locate the relevant images along with their corresponding "_thumb" versions.
3. Copy these images and share them with users who are unable to upload them.
4. On the affected devices, place the copied images into the same Uploads directory.

This should resolve the issue.

Hope this helps :)

Reported through teams feedback. TYSM!

Dear Angie,

Many thanks for the prompt response!

After thorough research, I notice similar behavior that has been reported previously, some users reported the same scenario, it could be possible a service degradation.

If you have the organization admin permission, you can also raise a service request to report this symptom to our online channel through the Microsoft 365 admin center. A support agent can further connect with you remotely, for further troubleshooting and involve the backend team where need be. Get support for Microsoft 365 for business -- Online support.

Alternatively, you may also provide report to our dedicated Teams developer team directly via in app feedback site. To do this, click on Three dot (next to your notification icon on the right top corner) -->Feedback-->Report Problem This tool allows you to describe the feature in detail and submit it directly to our product development team for review. I will do the same on my end.

I will also revert back when I get more info on this. Your patience and cooperation are much appreciated.

Best regards
