Question: I deleted an email account, when I try to add it back it errors that the account already exists
I am using OS X El Capitan version 10.11.6. I deleted an email account. I attempted to add the same account later and I get a message "account already exists". The account is no in any account list in settings or mail. Any recommendations?
