My OWA app has worked without a hitch for over a year now until this past week. It takes a very long time to load the app and server and when it does it says that an update is needed and then crashes. Deleting app does not help and there is no available update in the App Store. When the app DOES load I can view my inbox but when I try to read an email it says there is an error and the email is unavailable. Please make an update to fix these bugs, I need to be able to check my email on mobile!
I'm having this same issue since the recent 9/15/15? Update started downloading. It appears to be updating but that's been going on for several days now. I've tried deleting the OWA app from the phone and reinstalling. Called Office 365 support but they say there's no phone support for OWA. Said the was online support thru the OWA but this comment doesn't seem like support. My domain is cioatlarge.com. Please contact me ASAP. I've upgrade this iPhone 6 to iOS 9 and that didn't help.
