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?

    Where is this please and has anyone else had any further progress as we are still struggling to get a good enough quality background uploaded despite using the parameters mentioned in thread?

    We are on Version: 25060.205.3499.6849.

    Looks like this has been fixed; at least I managed to add our standard background, that did not upload earlier.

    I have Microsoft Teams version 25072.1609.3541.7814.

    OMG! I just wasted a whole day trying to upload 1920x1080px backgrounds.
    Thank you so much for the 1200x675px tip.

    Last week I had 1 user report she resolved the issue via Start > Apps > Installed Apps > Microsoft Teams > Advanced > reset.

    Another user later reported they resolved the issue by resizing the image to 90% of its original size (below the 1800 x 1800 size threshold, I presume).

    So it looks like there may be multiple work arounds.

    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.
