Removing an obsolete orphaned account

Dear @Mike Grinshpon,

Based on your description, kindly try these steps:

1> Confirm it is not still connected under Access work or school

Do not rely only on Email & accounts.

In Start Menu, open Settings > Accounts > Access work or school.

If the retired work account appears, select it and choose Disconnect.

Restart the PC.

2> Remove the account from Email & accounts

After restart:

Go to Settings > Accounts > Email & accounts.

Under Accounts used by other apps, select the old work account.

If Remove is available, select Remove.

Restart again.

3> Sign out of Microsoft Teams

Open Microsoft Teams.

Select your profile picture.

Select Sign out.

Close Teams completely.

Reopen Teams and sign in only with the account you want to use.

If Teams still shows the old organization, please check whether Settings > Accounts and orgs has an option to leave the old organization. If the old account no longer exists, this option may not always be available.

4> Clear cached Teams and Windows identity data

If the obsolete account still appears, please clear the local cached identity data.

Quit Teams completely.

Open Task Manager.

End any remaining Teams or ms-teams.exe processes.

Open File Explorer.

Paste each of the following paths one at a time into the address bar.

Delete the folder if it exists:

%LocalAppData%\Packages\MSTeams_8wekyb3d8bbwe

%LocalAppData%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

%LocalAppData%\Microsoft\OneAuth

%LocalAppData%\Microsoft\TokenBroker

%LocalAppData%\Microsoft\IdentityCache

Restart the PC.

Open Teams again and sign in with the correct account.

Please be aware that this may sign you out of other Microsoft apps on the device, such as Office, OneDrive, Outlook, or Edge. You may need to sign back in afterward.

5> Remove old saved credentials

In Start Menu, open Credential Manager.

Check both Web Credentials and Windows Credentials.

Remove any entries related to the old work account, the former organization, Teams, Office, OneAuth, ADAL, or MicrosoftOffice.

Restart the PC.

6> Check Office identity entries, if Office apps also show the old account

If the old account also appears in Word, Excel, Outlook, or other Microsoft 365 apps, please proceed carefully with the following steps:

Press Win + R > run regedit

Before making changes, select File > Export to back up the registry.

Go to this location:

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities

Review each subkey and check whether it clearly references the old work email address.

If a subkey clearly belongs to the obsolete work account, delete only that specific subkey.

Restart the PC.

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.
