DME is full of bugs. Not at all user friendly. It does not have to be so difficult to use. I mean its not a novel software, its just another mail client. The company should hire some usability engineers to improve GUI and how the data is handled by DME. Contacts never sync, Calender syncs only when I m lucky :/ Folders under inbox never sync. Old folders that are deleted always appear. I mean, come on DME team. How can you not see such simple things when you test your software before releasing it. Overall: Very Disappointed !
