error message: Mail can't connect to the account "Yahoo"
Talked with Apple support and could not get this resolved. We first tried going to Mail Preferences and making sure everything on the accounts were correct. I do have two Yahoo email accounts on this computer. Next time I called we went to System Preferences - Mail, Contacts, & Calendar's and deleted each account. Then added them back. I'm still getting the error message.
