If you receive an error when opening an Office document (the most often used app is Microsoft Word), keep the application open.
A typical error can be that you only have read access to the open file.
Another error mentions "Couldn't Verify your account", like the image below shows:
If you are seeing any of these errors, look at the upper right corner of your Office application to see if there is a warning icon next to your name and click on it to choose the "Sign Out" option.
When signing out, you will receive a warning message about "Removing your account". Select Yes instead of the default selection of No to continue to sign out.
Then, go back to the upper right corner and select the "Sign In" option, where you will then be redirected to sign in with your Microsoft account (use your full Geneseo email address).
Continue to authenticate and sign in to now use your Microsoft Office apps as you normally would.
