Another account from your organization is already signed in on this device. Try again with a different account.

I've been using Microsoft 365 (through work) for 8 years now on my personal Macbook with no issues until yesterday. Yesterday I tried to do some work in Excel and it wouldn't allow me to save it because I needed to sign in. I thought that was strange because I never logged out, but hey no big deal I'll just sign in. But when I try to sign in, I get this error message, "Another account from your organization is already signed in on this device. Try again with a different account." The reason I know this can't be true is I only have 1 Microsoft 365 account and this is my personal computer. So I need help being able to log in. I'm not able to save any documents in any of the apps.

Microsoft 365 and Office | Subscription, account, billing | Other | MacOS

UPDATED May 5th, 2023

There is a new solution way at the end of this thread..reprinted here that I have used 3 times this week, with 100% success!

"For Mac devices, follow these steps:

  1. Close all Microsoft 365 apps.
  2. Open Terminal, and then run the following command: 
     defaults write com.microsoft.Word ResetOneAuthCreds -bool YES
  3. Open the Microsoft Word app and continue with the activation steps." My older Post: I also have the same issue with this, on a Mac macOS 11.7.2

Started about 2 weeks ago...

There are 2 user accounts on this Mac and each has their own Office 365 License - and sign in as themselves within their own login account.

If I uninstall every single part of Office it goes away - for the first user who signs in..but once the second user logs on the issue returns.

Using the License Removal Tool - does nothing - I also found a script thats named MS Office ActivationTroubleshooter - it does nothing either.

I have (Today) installed the Mac OS 11.7.2 update - no change and the Office 16.68 updates - also no change.

My thought was to have each user sign out of Office when they log out of the computer and then sign back in when they log back in. These users work 3 days at a time... so they each have their own Account on the Mac. But this did not work either. Once the second user signed in it was locked up.

Here is an exact screen shot of the error.

    I have been wrestling with this on my Mac since last Wednesday, May 3rd, 2023. Microsoft's support tried to help, but nothing resolved the issue. Uninstalling, running the License Removal Tool did not work. Completely uninstalling all MS products and reinstalling them didn't work. 1Merlin's terminal command worked! Thanks!

    Mac: This issue related to iCloud's Keychain refusing to dump the key. No matter how many times i deleted keychains this did not solve the issue until i signed out of iCloud and then validated Office/Word.

    Now fixed.

    To solve my problem on an iPad, I went to settings, outlook, reset credential and that solved the problem.
