I reached a frustration level where all I wanted was a stupid widget that would display my Exchange email unread count. I ended up stopping the use of the built-in Exchange synchronization and I am now using Moxier Mail. It seamlessly integrates and does everything that the built in client does, including contacts, calendar, notes, tasks, etc, except it it seems (to me) to have a little bit of a cleaner interface. The obvious advantage is: When you put the Moxier Mail widget on your phone's desktop, it shows unread mails! Heck of an expensive widget just to get an unread count, but it is worth it for me. Now, I just need a Google Voice notification tool and I'll be golden.
