For me, the office reset tool did not help. What solved this for me, was to remove any Microsoft entries in keychain access, then I downloaded and ran the licence uninstaller ( https://support.microsoft.com/en-us/office/how-to-remove-office-license-files-on-a-mac-b032c0f6-a431-4dad-83a9-6b727c03b193?ui=en-us&rs=en-us&ad=us ) . When I opened an Office program, it let me sign in with the desired organization account.
