A problem has arisen where Outlook is concerned. Some users are unable to sign into their Outlook for Microsoft 365 accounts. Whenever they attempt to do this, an error dialog shows up stating the user must sign in with their work or school account as they are not able to accomplish the task with their personal account.
You can’t sign in here with a personal account. Use your work or school account instead.
Now, this is a problem the Outlook team is looking into, and will eventually release a fix to get things back to normalcy. However, not everyone wants to wait until that happens, so is there a way to bypass the error until an official fix is released? Yes, there is a way, and it has everything to do with turning off Support Diagnostics. For those who are not sure what that is, well, it is all about giving users the ability to submit an In-App ticket by using Help. The bug in question is related closely to how Outlook authenticates the diagnostics in certain situations.
