Preferences says "this account already exists" when trying to change password in Mail.

Mail keeps asking me for the password for my email account. When I type it in, it says "This account already exists." No problem, I think. I have had this email for over 20 years so, yes, it does exist. I think there must be a problem with my email/internet company, so I changed the password with them thinking I could just change the password on Preferences since it is a new password. No deal! I have tried different things, none of which seem to work. Suggestions??

If the email is IMAP, (or even GMAIL which is faux-IMAP), or Exchange, remove it and re-add it. You will lose nothing. and the problem may self heal


If the problem persists, odd as the advice may seem, try rebooting in Safe Mode before undertaking a detailed investigation. Safe Mode can clean up all sorts of things that get in our way.


If the problem persists there, create a new user, and add your mail account after logging in as the new user. If the problem is not present there then come back and a more detailed set of thoughts are likely forthcoming from an email expert
