Troubleshoot errors using your domain email address in Gmail

If your domain email address is set up in Gmail and it is no longer working, then here’s how to edit the server settings. In most cases the problem will be caused by Gmail no longer allowing the use of a non-SSL/TLS mail setup.

Is this the first time you’re setting up this email account? Then use our new email setup guides for Gmail on computer or Gmail on mobile, rather than this troubleshooting guide.

Change to your domain name.

Check your password

  • First check  your password by browsing to Webmail and trying to log in. If you aren’t able to log in, then you have the incorrect password. Forgotten passwords can be reset in konsoleH – you will need to get your domain or web administrator to update it for you if you don’t have konsoleH access.
  • Do you use a Mac Keychain? Make sure that the password saved in your keychain is correct – here’s how.
