How to Remove Old Office 365 Account From Windows 10

  1. Home
  2. Cloud
  3. Microsoft Office 365

I currently have a 3040 Micro on Windows 10. There are 2 users associated with this computer. Call them User1 and User2. User1 is a high permissions user and gets sensitive information and is User2's manager. User2 did not have a Office365 license when this computer was set up. We used one of User1's installs to install Office programs on this computer. User2 eventually got a license. User1 and User2's accounts were both signed into Excel. This was allowing user2 to see user1's private documents. Signed user1 out of user2's excel and deactived install from User1 so user1 is no longer associated with this computer. I go to Edge and make my way to the login portal to find out that User1's 365 account is "connected to Windows"
How does this happen? Because at this moment, User2 can click on this and is granted access to User1's emails. I have already cleared the cache and the credential manager on Windows and this has not solved the problem.

Check the setting to see if the account is associated or not.

Settings > Accounts > Access work or school

Also, check the credential manager and remove any credentials that shouldn't be there.

What precisely do you mean by "associated with this computer"? Did they each their own Windows login on the computer? Or were you having both of them log into the same computer account while playing fast and loose with the Office 365 licenses? (That license is per person, not free reign to install 5 copies of office anywhere and use them for anything.)

Sounds like the computer got logged on with a Microsoft account (cloud) rather than a Windows account (local).

First off, reinstall Office with shared activation. This will keep each user account on the computer completely separate as far as Office is concerned.
You need to use the Office Deployment Tool to do this, you can't use the click-to-run installer you download from the portal. This is not very complicated and is the correct way to install Office on PCs that will have more than one user.

Actually this is a fairly new thing with O365 Office installs - near the end of the install it asks you if you want to connect this PC with your Office account or something like that - I forget the exact wording.  This is where this is coming from and I haven't spent the time to track down exactly what it does.

I played around with mine - it also shows "connected to Windows" when I go to the portal.Stabby has it right - Settings, Accounts, Access work and school - you should see the account there and you can delete it.

The PC can be associated with the user via O365 - but each person should log into Windows as their own user.  That would also prevent User2 from accessing User1's stuff.
