[AC Question]

I had to do a factory reset the other day. That was ok. And then I set up an IMAP account with my earthlink email address - and that was done successfully but whenever I click on the email logo on the phone 'Account Setup' appears. The account has been set up already.. and I have no idea how to move on from Account Setup to actually seeing my mail.

Delete the account in the email client. Then do this:

Settings > Apps > All > Select your email client > Force stop > Clear cache > Clear Data
Reboot the phone and re-enter the email account.
Hopefully, that will do the trick.
