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.
