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.

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 had a couple of accounts such as info@ and ap@. I went in as the company administrator and signed those accounts out of all devices and it worked. Hope this helps.

    Thanks — something like this was what ultimately helped me. PPT was not showing any account logged in but eventually I was able to see a second account was present. Microsoft could perhaps help prevent this by making it easier to sign all users out of all office apps

    This just occurred today with one of our Mac-based users (I will call her Rachel). It turned out that it was caused by the removal of O365 licenses for former user's accounts that Rachel was still logged into on her Mac. I added the licenses back and Rachel then logged out of these user's accounts and cleared the keychain on her machine. Problem solved.
