This was not working for me; I did not add this to the ticket for Erik to do:


Erik,


Found this, but below is what I saw in case yours is different like mine.

To remove an additional account from Microsoft Teams, follow these steps:

  1. Open Microsoft Teams and click on your profile picture at the top right corner.
  2. Select “Settings” from the dropdown menu.
  3. In the Settings window, go to the “Accounts” tab.
  4. You will see a list of accounts associated with Microsoft Teams. Choose the account you want to remove.
  5. Click “Sign out” next to the account you want to remove.

What I see is 3 dots to to the left of my picture, when I hover the mouse over it, it says "Settings and more". Click it.


Then click "Settings" and go to "Accounts and orgs" to see something like this:


For me, I'm getting rid of "NTT Ltd" but you should see At Home here.

Then this opens a web page in Chrome like this for me. Click the Leave button


then this:


Click Leave again.

This you see this:


That wasn't enough. Needed to go to Chrome cookies with this:


chrome://settings/content/all

This worked for me. Erik however solved his issue on his own. He reported:


I think I successfully ejected from my At Home account Dan.
I opened Teams and then went to my my profile in the upper right. 
I clicked on my At Home profile and it gave me an option to sign out.
It then gave me a warning about deleting that account info, but I clicked sign out any way and now it no longer appears in my Teams account.
When I now join a Teams it does not get me hung up with an error / problem with account message so fingers crossed it is resolved.
