This guide will help you fix errors in the setup of an email account in macOS Sierra, Mojave, Catalina, Big Sur, Monterey or Ventura Mail.

Is this the first time you’re setting up this email account? Then use our macOS Sierra, Mojave, Catalina, Big Sur, Monterey or Ventura setup guide, rather than this troubleshooting guide.

Change example.com to 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.

Steps

  • 1
    From the top menu choose Mail > Preferences... or Settings... preferences
  • 2
    On the Accounts tab, choose the relevant account from the list on the left, and check:
    • Enable this account is checked
    • Download attachments is set according to your preference
      • 3
        Click Server Settings                                                                   kh-sierra-accounts

        Check:

        Incoming Mail Server (IMAP)
        • User Name is the full email address
        • Password is correct – forgotten passwords can be reset in konsoleH
        • Host Name has mail. before the server name e.g. mail.example.com*
        Outgoing Mail Server (SMTP)
        • User Name is the full email address
        • Password is correct – forgotten passwords can be reset in konsoleH
        • Host Name has smtp. before the server name e.g. smtp.example.com*
        • 5
          Deselect (uncheck) the boxes for Automatically manage connection settings for both Incoming and Outgoing Mail Servers – additional fields will now be displayed.
          • Select Use SSL/TLS for both Incoming and Outgoing Mail Servers.
          • Incoming Server Port is 993 for IMAP or 995 for POP
          • Outgoing Server Port is 465
          • 6
            * Note: In isolated cases mail.domain (e.g. mail.example.com) and smtp.domain won’t work. In these cases you will need to use the server name instead e.g. www34.cpt1.host-h.net. Find my server name.
          • 7
            Click OK and Save (Note: this button only becomes visible when settings have changed).

          What happens next

          Your macOS Sierra/Mojave/Catalina/Big Sur/Monterey or Ventura mail is now set up correctly.
