Review for Owl for Exchange by jwbell
Rated 4 out of 5 stars
Seems to work the same or as well as ExQuilla which the author also manages. I would have given it 5 stars if EWS wasn't flagged as experimental. It took me a couple of minutes to figure out what to put in the username and webmail boxes for ews, but overall it was easy to setup.
