Additional meeting and call-related features and issues within Microsoft Teams for business
I got it to work on my problematic PC.
I did this -
- Exit Teams and Outlook
- Delete the %appdata%\Microsoft\Teams folder
- Go to a PC that does have backgrounds working and zip the %appdata%\Microsoft\Teams folder
- Copy it to the problematic PC and extract to %appdata%\Microsoft\
- Start Teams
- Enjoy your backgrounds!
