  • Password: the password set when creating the email account
  • Incoming server: mail.yourdomain.com

Tip: If you are unsure of your server settings, check the Mail Server Settings article for complete details.

Troubleshooting

"Cannot connect to server" error:

  • Verify the server hostname is correct
  • Ensure ports 993 and 465 are not blocked by your firewall or ISP
  • Try port 587 with STARTTLS for outgoing mail

"Authentication failed" error:

  • Double-check your password (case-sensitive)
  • Ensure the username is your full email address, not just the part before @
  • Reset your password in the control panel if needed

Emails not syncing:

  • If using IMAP, check your folder subscriptions in Outlook
  • Verify your mailbox is not over quota in the control panel

Certificate warning:

  • This can occur if you are using mail.yourdomain.com without an SSL certificate. Use the server hostname provided in your welcome email instead.
