For some users in our corporate office we use Office 365 for Mac. We have a couple users using Office 365 and have downloaded Office 2016 on their Mac. Of these four users, only one is having the issue that is not allowing them to edit documents. For about three weeks they were fine but recently started getting a message that their account does not allow editing. This is effectively stopping them from working altogether.
What I have tried:
1. Clicked "Use another account" and had the user sign in with their Office 365 credentials.
2. Clicked the "Activate" button on Word and had the user sign in with their credentials there.
3. Logged into portal.office.com to confirm the user has a license for "the most recent desktop software"
4. Confirmed the user is assigned a Mac 365 for Business license.
What else can be done to get this user working?
