5 stars: Fantastic - like Outlook should be!! I was initially hesitant about the price, however having tried lots of email, calendar and task apps this is by far the best and worth the money, especially as it includes categories which are a part of my workflow. Bliss!!
5 stars: By far the best email app I've found for Android--if there's any app worth paying for, it's this one. The app now works with IMAP in addition to Microsoft Exchange, but the Exchange features are where it shines. It's feature rich and syncs great with Outlook on my desktop. It looks great, is easy to use, and gets frequent updates.
4 stars: update: solved issue
5 stars: I have tried out many but this is by far the best mail app.
5 stars: Great app for Ms Outlook 365 and Exchange. Very customisable, and allows categories.
5 stars: One of the best email client for business
5 stars: Works great, much better than any other (I have tried most) exchange email. Integrates property with other apps. Keeps getting evolutionary improvements. Thank you
5 stars: Everything is great except address book. It only syncs my contacts and I can't access global address book. Thank you for explaining in the comment. Now it's 5 stars, keep the good work.
5 stars: I like having shared calendars finally from Office365, but the days were not in sync with my regular calendar, one was off by one day and another was off by a full week - issue resolved
4 stars: paid version doesn't allow to config...
