    Welcome Mike Bennett,

    I understand how frustrating it can be after upgrading to Windows 11 and installing Microsoft 365, you are unable to add your BT Email account to Outlook. 

    Before proceeding, I need to narrow this down slightly: 

    • Does the setup fail during automatic configuration, or after you enter the password? 

    In the meantime, you can try the workaround steps to troubleshoot the issue:  

    Step 1: Open Outlook and select Add account

    Step 2: Enter your full BT email address and select Continue

    Step 3: When automatic setup fails, select the option to set up the account manually

    Step 4: Choose IMAP as the account type

    Step 5: Enter the following server details exactly as provided by BT:  

    • Incoming mail server: mail.btinternet.com 
    • Port: 993 
    • Encryption method: SSL/TLS 
    • Outgoing mail server: mail.btinternet.com 
    • Port: 465 
    • Encryption method: SSL/TLS 

    Step 6: Use your full BT email address as the username, enter the password, then complete the setup

    I really hope that the information I gave above was helpful to you. Please feel free to reply below and let me know if you have further concern on this matter.
