Is there a solution yet to the 365 Error “You’re currently signed in with an Office 365 email account, which can’t be used with Outlook.com”.

Both threads I found relating to this issue are both locked.  None of the solutions offered in these threads solved my access issue.  I have found no further possible solutions to this problem.

I cannot access my .edu email.  Can someone please help? 

I'm willing to provide all the information needed to investigate this issue.

Thank you.
