Guests receive a "access denied" after a period of successful access

Iron Contributor

I'm working on a customer tenant with my AAD credentials. The customer invited me into a Office 365 Group as a Guest. The access is working fine and I'm also getting the email. At the moment we are working on a really large document with multiple people. I work onsite and most of the times I open the document (in Word 2016 current branch on my AAD joined Windows 1703 device) and work all day. Sometimes the document is open for more than 8 hours.

Yesterday I received at the end of the day an error message and word was not able to upload the document. I could not figure out how to fix this problem. Upload center showed a permission error and allowed me to do a sign-in. After a successful sign-in the document was still stuck in upload center. I opened the SharePoint site (of teh group) directly but I also received an access denied message, also I was working on the document and the site all day.

Any info what the problem is? Is this by design?

No, it is not normal.

If an owner has not modified the permissions (first of all, you should confirm it...), you should open a support ticket.
