When opening Office 365 Word documents it is showing this message:
Office 365 Sign-In Required We can’t save, or check for, changes because your cached credentials have expired. Please sign-in again.
I tried to sign in however it says “Sorry, another account from your organization is already signed in on this computer”
- In Word go to File -> Account, sign out of all of your accounts and login with your main OneDrive account.
- A restart may be required
If you still have the issue try:
- Quit all Office Apps. Go to the Control Panel, User Accounts, Credential Manager and remove all credentials relating to Office 365.
- If you still have this issue after trying the above fix please read this MS Article
Interestingly it mentions “However, Office 2013 only supports one Office 365 user sign-in from each tenant or organization per session.”.
It also says “This behavior is expected. It occurs if another account is already signed in to Office 2013 by using a different Office 365 user account within the same organization.”
