How remove a corrupt Account that showing as a work or school but I didn't set up no option to delete

Hi @Oozlum, 

Thank you for posting your question in the Microsoft Q&A forum. 

We're sincerely sorry for any inconveniences or troubles this issue may have caused you. To help you resolve this concern, could you provide us with more detailed information? We greatly appreciate your understanding and cooperation.   

• Which platform are you using Teams (desktop app or web version)? 
• What happens exactly when you try to "follow screens"? Please describe clearly the steps you took 
• What happened when you tried to remove it? Is there any error message? If yes, can you share us the full wording of the error 
• Is this your personal Mac or was it ever managed by a company? Is there any Management Profile on your Mac? You can check via System Settings > Privacy & Security > Profiles 

If possible, may you share us screenshots of your situation so we can clearly understand your situation and provide the most appropriate solution. 

In the meantime, you can try following these guidelines to remove old account from Teams desktop. This is the guideline for MacOS Sequoia 15 but it can also work for MacOS Tahoe since their core systems for account and profile management are the same: 

Step 1: Remove the old account 

• Click the Apple menu in the top-left corner > Select System settings  
• In the sidebar, look for Privacy & Security > Scroll down to find Profiles. 
• If you see a profile listed, select it and click the minus (-) button to remove it 

If the account is stuck and not removable via the UI, you can delete the account file using Terminal 

• Open Spotlight and search for Terminal. 
• Run the following command to list all accounts: dscl . list /Users  
• Look at the list and find the "username" associated with the account you want to remove 
• To delete the user account, use the command: sudo dscl . delete /Users/"username" 

Step 2: Clear cached credentials (keychain access)   

Microsoft stores login tokens in your macOS Keychain. You need to delete those manually:   

• Open Keychain Access (Command+Space and type Keychain access).   
• In the search bar, type: Microsoft or your old work email.   
• Look for entries with:   

Microsoft   

Office   

ADAL   

Com.microsoft   

MSOpenTech   

• Right-click and delete any entries related to your old account.   
• Be careful not to delete unrelated system credentials.   

Step 3: Delete Microsoft identity data   

• Open Finder > press Cmd + Shift + G to open Go to Folder.   
• Enter each of the following paths and delete the folders below if they exist: ~/Library/Group Containers/   
• Delete these:   

UBF8T346G9.Office   

UBF8T346G9.OfficeOsfWebHost   

UBF8T346G9.ms   

Step 4: Reboot your Mac and try logging in again to see if issue still persists  

Please understand that our initial response does not always resolve the issue immediately. However, you can try workaround and let us know how it went or if you need help with any steps, we can work together to find a solution.    

Thank you for your understanding and cooperation. I'm looking forward to your reply.
