Mail Server: Exchange Server 2010
Phone: iPhone 4s
Trying to sync my iPhone to the company mail system. When setting up in the usersname I put the domain\username and password. I leave the Domain field blank and everything syncs.
However, I back out and go back into the email account settings and the domain name has moved up to the domain field and my usersname is left with just the username. From there I am unable to sync.
