[ARCHIVED] Canvas Collaborations (Office 365) stopped working

[hmcneill]

We use Office 365 Collaborations in Canvas. Today previously working collaborations are no longer accessible to staff or to students from the link in the course. 

I have tried different users, different browsers and different courses but nothing has resolved this. Occasionally we can get access on one course, but for another it won't work at all. Users are not taken automatically to the file, but instead are asked to log in, the authentication pop-up appears successful but after a while a screen appears saying 'You are not allowed to view this content'. There is no issue with our SSO and the course link to Office 365 OneDrive is working ok. 

I have contacted Canvas 24/7 for support but they have no further suggestions at this stage other than speaking to our IT team. Any suggestions to help resolve this would be welcomed!

Hello @hmcneill 

I understand that you are having some issues with Collaborations in canvas. 

Collaborations can be tricky sometimes when they stop working.  In my experience there can be a few things that will cause issues such as this. 

• Occasionally if the student is signed into a personal email, other than the one used for Canvas, it will try to authenticate with that personal email and they will get a message saying that 'You are not allowed to view this content.' Sometimes this can be solved by having the student sign out of their personal email addresses on their browser that they are using when this happens. Clearing cache on the browser can also sometimes resolve this because it will sign them out of all their accounts. 
• O365 will collect an access token in the students Canvas account. Sometimes having the student remove any old access tokens from their account settings will allow them to re-authenticate with their default email address in canvas. HERE is the student guide for managing tokens. 
• A blocked permission in the browser for Pop-ups and redirects can sometimes come into play if they are not being redirected to the collaboration on O365. occasionally students will accidentally block that permission on accident. 
• Sometimes the student will have an unconfirmed email address in Canvas. When they try to authenticate, it will not be able to do so because the address is not sure which address to use for the Collaboration. I don't see this much, but it occasionally happens. 

Hopefully this helps!
