Sorry another account from your organization is already signed in on this computer

I’ve now fixed this error two different ways. Most recent is listed as #1, the older fix is #2.

#1

I had a user that was having issues with their M365 licenses being deactivated. Pop ups going off like crazy. I did the usual troubleshooting first, Windows updates and Office updates, but this did not help. I looked at credential manager,  removed the work account from the accounts area, didn’t help. But what fixed it was removing the en-us version of Office. The client actually had two versions installed, the home and business. Business will state “Microsoft 365 Apps for Business”. That’s what it was. I also signed them out of the User Information area first.

 

#2

This one can be a “slay the Outlook dragon” fix for you techs out there. What I have found it means, is that Outlook is unhappy with the other profiles in Outlook and how they are connected to the Office 365 account.

For this repair:

• I had to delete all Outlook profiles. If you cannot open Outlook, be sure to get a COPY of the OST files before you do this. Some clients have data in the OST file that cannot be recovered easily.
• You can also try deleting all credentials and registry too but deleting the profiles should do it.
• After I deleted all the profiles, I launched Outlook and signed in with one account.
• Then I logged into the Office 365 account in the User Information area.
• Launched Outlook and added the other accounts.
