Unable to update email account password (or create email account)
This issue is with my iMac running macOS 12.0.1 and my Cox email account. Cox recently required me to update my email password. I did so. Mail would not accept the new password. When I tried to enter it, I was told "This account already exists." This was true whether I tried to enter the new password through mail's account menu or through system preferences.
So, I deleted the account. Made sure my software was up-to-date and restarted my computer. Now, mail will not allow me to add the account. I get the same error message: "This account already exists."
The new password works just fine with my IOS devices, just not on my iMac. The email address for this account is the one I use as my Apple ID. Any suggestions?
