I need to change the mail server for a IMAP account in OSX.

But the mail server field is greyed out (see below screenshot). Ideally i dont want to have to setup the account new from scratch a re download all the emails from the server.

Is there a way i can edit the mail server field of an existing IMAP account ?

I found the answer after some searching via HERE

  • Select the Advanced Tab, uncheck the box to “Automatically detect and maintain account settings”, save change.

  • Go back into Preferences > Accounts, update the Incoming Mail Server to: mail.comporium.net
