The Dec 2015 version was great for most of 2016 but...


This version of the OWA app was published December 2015. I experienced some issues with this version initially, but those were sorted out at the server side. Since February 2017 this OWA build has been unstable. I've purged local fat, removed the app, rebooted and then waited over 24 hours to let Apple iOS housekeeping remove those things left when one doesn't wait. No matter how many times i do this, the app is not stable. Clicking on buttons often do nothing, other than show the tap UI response. New email button, wait 6 minutes, new email form finally shows.

No, I am not out of space on my device. I am an Office 365 customer who also has on-premises servers. I have the most current version of iOS there is. I have an iPhone 5S, which was relatively new when this version of OWA was released.

It looks to me as though this is a hybrid app using either WebKit, UIWebView or WKWebView. Since 2015 Apple has made major changes to all three of these. Either Microsoft needs to update the HTML, JS and CSS the app downloads from the Internet, or this app needs some TLC. The non-OWA iOS Outlook shows a new build this month, March 2017. ❤❤❤

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.
