This guide will help you fix errors in the setup of an email account in older OS X 10 versions

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

♦ Replace with your domain name

First, check your password

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 control panel access.

Do you use a Mac Keychain? Make sure that the password saved in your keychain is correct – here’s how.
