my personal outlook and team keep on defaulting to an old business account a company i am no longer with

Hi @laurent chardonnet,

Thank you for reaching out to Microsoft Q&A Forum.

Your Outlook and Teams apps keep defaulting to your old business account because cached credentials and linked organization settings are still present on your device and Microsoft account.

You can clear your credentials cache, remove all of your Microsoft password and usernames from your computer to ensure a clean reset

1. Please sign out your accounts from Office applications, then close all Office applications.   
2. Open File Explorer, paste the following path, and delete all files and folders. %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy   
3. Go to settings > Accounts > Access work or school
4. Check if you can see your school account in "Access Work or School".   

If you can see it, please select it and select Disconnect. After that, please click "Connect" and log into your business account again to register the device.   

1.  Clear Cached Credentials   
   • Open the Control Panel on your PC.   
   • Go to User Accounts → Credential Manager.   

• Under both Windows Credentials and Generic Credentials, look for any entries related to your Microsoft 365 account.   
• Select and remove those entries.   
• Restart your computer and try adding your account in Office again.   

Download OLicenseCleanup.vbs and run it. In this way, you can use this package to remove license, remove cached identities in HKCU registry and remove credentials. For more details, you can refer to this article: Reset Microsoft 365 Apps for enterprise activation state. 

• Reboot your device. 
• Reopen Office apps and sign in with the correct account.  

I hope this information is helpful.
