Is this the first time you’re setting up this email account? Then use our new email setup guide, rather than this troubleshooting guide.

Replace with your domain name

  1. Launch Windows 10 Mail

2.  Choose the Settings icon at the bottom of the screen


3. Choose Accounts


4. Choose the relevant account


5. Choose Change mailbox sync settings


6. Scroll down and choose Advanced mailbox settings



7. Scroll down to Sync options and check that:

  • Incoming email server starts with mail. followed by your domain name e.g.*
  • Outgoing (SMTP) mail server starts with smtp. followed by your domain name e.g.
  • Tick all 4 blocks
  • Done

Your mail should now be setup correctly.

* Note: In isolated cases mail.domain (e.g. and smtp.domain won’t work. In these cases you will need to use the server name instead e.g. Find my server name.
