Far Better than the default iOS mail app


This app is much better than the iOS mail app, if you use this for searching alone, it actually gets results that are relevant and correct (the iOS mail app misses data in searches so many times). It's fast and reliable! Great app and I've used it for a long time now and like it better the more I use it.

After reading the reviews for this app I was really worried. But I tried it anyway. I've used exchange for over 15 years so I've seen owa go from bad to good. This is a great app and it allows searching of my entire mailbox, something that iOS doesn't do a good job at. Interface is good and it is easy to navigate and use. At first I couldn't find send new email button, but it's fine and works good.

One more thing, you don't have to have office 365 (even though it says you do). It connects great to a on-site exchange system.

I would recommend this!

Update: After using this app for a while, it really needs some fixes/enhancements : 1. It needs to have the option to fit to screen. 2. Needs to have ability to pinch to zoom in/out. 3. It needs Notes from your outlook. 4. Needs tasks from your outlook. 5. Needs a way to give app feedback and report bugs.

I still really like the search feature and the offline mode in this app. Still recommending but lowering my review ranking to 3.5 stars (4 because I can't go 3.5)


I haven't ever written a review before this, but I am SO frustrated just trying to get the app to perform basic functions. As others have noted, over the past couple of weeks the app simply crashes within a second of opening it. More irritating to me is it is syncing with a database that then gives me two, three, and as much as seven duplicates in the contacts section. Adding an event to the calendar is difficult because you have to touch the day/date you want vs scrolling. Try as I might, when trying to scroll to the correct date, it overshoots then undershoots the date. I only recently discovered that you have to "tap" the date you want, not scroll. Sheesh. I have lost calendar events/meetings consistently. Again, I don't know where it is pulling some of its data (sometimes from the native calendar on the iPhone, sometimes from my Outlook program on my desktop). Maybe they should stick with a product that works and improve that, as opposed to forcing us all into their Office 365 platform -- which I still can't see any utility for me.

Worst App on my Phone

This app only works 1 out of 10 times the way it should when we go to use it. There are 3 of us on our team at work that have this app on our iPhones (I know, the IT group didn't think that one through - Microsoft email on an iPhone) and all 3 of us have the same results. It doesn't matter what version of iOS or what type of phone it is either (ranging from iOS 9 to iOS 10 and iPhone SE to iPhone 7). This app either freezes, crashes or won't let you open your folders. Like I mentioned in the first sentence, to get it to work for even the "lucky" 1 out 10 attempts, you have to completely close the app and launch it again, and cross your fingers - even in the middle of reading an email!

Unfortunately, I need to have this App for work because we use a "shared" mailbox and this is the only way we can access that mailbox from our company provided iPhones. This app just solidifies my distaste for MS that much more.

I would rate it with less than 1 star if I could!
