Using Classic Outlook on Windows for personal email, calendar, and contact management
For BT email in classic Outlook for Windows, the password must first be changed with the email provider, then updated in Outlook.
- Open Outlook and select File.
- Under Account Information, select the BT account.
- Select Account Settings.
- Select Server Settings.
- Select Incoming mail or Outgoing mail.
- Update the password there, then select Next > Done.
If Outlook does not show a password field or keeps using the old password:
- Close Outlook completely.
- Open Credential Manager in Windows.
- Select Windows Credentials.
- Under Generic Credentials, remove saved entries related to Outlook, Office, or the BT email account.
- Restart the PC.
- Open Outlook again and sign in with the new password when prompted.
If that still does not work, create a new Outlook profile:
- Close Outlook.
- Open Control Panel > Mail.
- Select Show Profiles > Add.
- Set up the BT account again with the new password.
If the BT account needs manual setup in Outlook, use IMAP with these settings:
- Incoming mail server: mail.btinternet.com
- Port: 993
- Encryption: SSL/TLS
- Outgoing mail server: mail.btinternet.com
- Port: 465
- Encryption: SSL/TLS
- Username: full BT email address
