Love the fresh presentation at the top... ...quick, efficient.
Hate the message delivery...
1/2 the time messages off the screen...
...having to zoom out, pan, scroll to try and read messages that should simply be formatted to the iPhone screens.
Same in composition.
Why do 1/2 the job?
Finish it off properly, and it will be the best Outlook Exchange client on iPhone.
Right now close to unusable.
