We are trying to upload 1920 x 1080 custom backgrounds and we are getting an error message saying invalid size. Testing other sizes, anything square 1:1 works but gets cropped in the viewer. We also tried 1280 x 800, but same gets cropped. There isn't mention of this update in any of the update logs. What is the correct size, is there a template to follow to know what gets cropped?

    We have fixed the Problem, uninstall Teams and downloading the act. Version with ending .2155 from Download Microsoft Teams Desktop and Mobile Apps | Microsoft Teams. Than the backgrounds works.

    That is not a "fix" it is a workaround. This is not practical when you have several thousand users on a mix of PC and Macs and they dont have admin rights.

    I've been testing sizes and 1200 x 675 pixels uploads and keeps the same ratio as 1920 x 1080.

    Will Microsoft be releasing updated dimensions? This issue came with the latest update.

    We are having the same issue. Any pictures we try to upload will result in the error: invalid size (even when it's within size limit). But if you use the same picture and use app like Photos to resize/reduce it to 90%-75% and save, the new file will upload fine. It's the only workaround we have at this time.

    Hi Inema,

    I am using Version 25044.2407.3474.4587 (25044.2407.3474.4587). Yes, this happens after restarting. Multiple people in our company are having this issue, trying both jpeg and png on both Mac and PC. Our original images are 1920 x 1080 pixel. This is not working and we get the error below.

    As this effects multiple users on our teams, we would need to send out a company wide cache clear, if that is the case. I will try shortly on mine and reply back.

    Thank you!

    Angie

    This is now listed in the Service Health Page:

    Users may be unable to upload background images larger than 1800x1800 during Microsoft Teams meetings

    Issue ID: TM1040294

    Affected services: Microsoft Teams

    Status: Service degradation

    Issue type: Advisory

    Start time: Mar 24, 2025, 11:38 AM CDT

    More info

    When attempting to upload a background image larger than 1800x1800, users receive an error message stating "invalid image size" and the upload fails. Users can avoid this issue by resizing the desired image to below the aforementioned dimensions.

    Scope of impact

    This issue may affect any user attempting to upload a background image larger than 1800x1800 during any Microsoft Teams meeting.

    Root cause

    A recent change instituted a restriction on image size for background image uploads in Microsoft Teams.

    Current status

    Mar 26, 2025, 3:37 PM CDT

    Our fix to revert the strict size check logic has been validated and we're expecting deployment to start by Monday, March 31, 2025, which is when we anticipate providing an updated timeline for impact remediation.

    Next update by:
