- On the File menu, click Account Settings> Manage Profiles > Email Accounts (or Show Profiles if you have more than one profile).
- Double-click on your email account from the list then to open the old Change Account page.
- On the POP and IMAP Account Settings:
- Make sure the Incoming and Outgoing mail servers end in "his.com".
- Click More Settings.
- For IMAP, use port 993 + TLS
- For POP, useport 995 + TLS
- Click the Outgoing Server tab.
- Make sure the server name ends with "his.com".
- Check the My outgoing server (SMTP) requires authentication option.
- Click the Advanced tab and change the Outgoing server (SMTP) port.
Enable SSL: change the port to port 587 with SSL/TLS from the encryption drop-down menu
(or use 465 and select SSL).
- Save the settings.
Note: you can only change POP3, IMAP, and SMTP passwords using this method.
