I cannot create a new account for the same email address unless I delete the existing account. I don't want to do that as I need access to the existing emails.
I have changed the account name, deleted the email address in the account settings, and changed the user name in the server settings, and un-checked all the server settings.
Then I create a new account using the same email address, but IMAP this time and a new password. Always get the error message " Configuration could not be verified - is the user name or password wrong?"
What do you think the answer is?
