Customizing the visual backdrop during video calls to enhance privacy or presentation
Thank you for the reply, this helped me as well!
Please note, the requestor asked about Mac, not Windows, there is no such thing as %variable% anything on macOS.
That said, it appears to be:
~/Library/Containers/com.microsoft.teams2/Data/Library/Application Support/Microsoft/MSTeams/Backgrounds/Uploads
Just as a side note the "com.microsoft.teams2" part of the path refers to the folder named "Microsoft Teams (work or school)" at least on my Mac. So navigating in Finder the path would be ~/Library/Containers/Microsoft Teams (work or school)/Data/Library/Application Support/Microsoft/MS Teams/Backgrounds/Uploads.
Although it appears to rename the file with some kind of GUID or UUID when manually uploading from within the Teams app. which means just placing the file there isn't enough.
Yes, this seems to be the case. If you wish to place the bg files straight to the folder (and not uploading them manually from the Teams application) you need to change the file name to random GUID and add thumbnail picture (280 x 158 px) with the same guid with "_thumb" suffix. There's some discussion about the matter here as well: https://www.reddit.com/r/MicrosoftTeams/comments/1428g7b/teams_21_teams_for_work_preview_and_background/ .
