Problem

Unable to edit an Office365 document on a Mac

Solution

In most cases this issue is caused by the application losing the connection with the Office licensing server.

  • First you need to force the Office application to sign out of the account. 
  • You can do this by opening Word or Excel and click on "Word" or "Excel" and select "Sign Out". 


  • This will display the Account information for Office and you should see an option to Sign Out
  • Then, REBOOT the Mac
  • Next Open Word Again
  • This time, at the top it will say it's not Activated - Click the Button to Activate Office

  • When the Activate Office box pops up, Click Sign In at the bottom of the box.

  • At this point you should be able to sign back in using your WHOLE WSU email address and password.
