Tried using Microsoft One Drive External Tool for the first time today, since other options for students turning in work has not been successful.  In the morning, students were able to open the document, type in the document, refresh and submit without problem.  By the afternoon submissions started failing, and with my last class, students were not even able to open the document.  Instead they received this error message:  

Requested value 'TenantIdsToBypassSharepoint403ExceptionInUserInit' was not found.

Please help.  Without students being able to submit work, Canvas does not work for me.
