Hello,
Thank you for posting in Q&A forum.
You need to check the applications involved. You can download Process Explorer and run it. The easiest way to track these processes in Process Explorer is to first press Ctrl+F to start a search. Search for "Microsoft Account Sign" and click on the result. You will see the applications (or services) associated with the instance of Microsoft Account Sign. Then check these applications that may be problematic.

Best regards
