Office 365 Your Cached Credentials have expired

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.

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”


  1. In Word go to File -> Account, sign out of all of your accounts and login with your main OneDrive account.
  2. A restart may be required

If you still have the issue try:

  1. Quit all Office Apps. Go to the Control Panel, User Accounts, Credential Manager and remove all credentials relating to Office 365.
  2. If you still have this issue after trying the above fix please read this MS Article

Interestingly the MS KB article 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.”

Happy Days!

    I’ve tried your solution.
    Once I enter sign in again, I get this error message

    Something went wrong
    Your computer’s Truster Platform Module has malfunctioned. If this error persists, contact you system administrator with the error code 80090016

    Server message: Keyset does not exist

    Do you have any idea how to resolve it ?

    After calling MS support, we’ve installed latest win10 major update by downloading win10 iso file. It took around one hour to update my computer. Finally, we succeeded to go through HELLO pin code process
