We've been experiencing a few problems in OWA with devices where people have upgraded to iOS 8.0.2 and 8.1

For example, the calendar does not display any events, nor does it display any shared calendars on the left hand side.

Admittedly, we are still on Exchange 2013 SP1 mainly because we are in a 2007 mixed environment and CU6 would give us more than a few headaches.

Having looked through the KB articles for CU5 and CU6, there doesn't seem to be anything that would directly relate to changes to the rendering that could alleviate this problem.

Has anyone else experienced this and does anyone know if either of the CUs would resolve the issue?

Thanks

Can you clarify something? Are you viewing OWA via a browser on the phones or are you talking about activesync on the phones?

OWA in a browser on an iPhone and iPad

Andy

What browser are you using to access OWA on the devices? Is it Safari or Chrome? If it's chrome can you try Safari?

Safari, although from what I understand Chrome would use the same rendering engine on iOS (by embedding UIWebView)

Hi,

I test it in my iPhone with iOS 8.1 and it works fine.

To narrow down this issue, I would like to collect some information.

1. Does this issue occur in the iPhone or iPad with iOS 8.0.2?
2. Please switch to Outlook client to check this issue.
3. Please log into the Light version of OWA to check this issue.
4. When try to add any event in calendar, does any error show up?
5. Does this issue occur in other users OWA?

Thanks.

Thanks for the reply

1. Yes, we've confirmed on iPad in iOS 8.0.2 and 8.1 (works in 8.0 on iPhone, but the bottom bar allowing you to switch to calendar etc is not visible if opened when other tabs are present)
   
2. Everything is fine in Outlook on a PC, OWA in IE or Firefox on a pc
3. No issue in OWA Light, it works as expected
   
4. No, it creates an event successfully but does not display anything
5. Yes, anyone using iOS 8.0.2 or above (haven't seen 8.0.1 to confirm, I know it works in iOS 8.0)

Thanks

Andy

Not sure if its related but my exchange server OWA also took a dump. I reinstalled the entire server because hey worked before and now it doesn't. -- Only thing could be my custom code that I injected into OWA virtual directories right? right?! Anyway long story short I didn't grab a snapshot/backup. So after importing and recreating everything same problem! Turns out Chrome has removed PopupModeDialog -- look into if Safari has done the same or if they directly use their most updated framework.

This was removed from Chrome earlier this month.

Custom code for the fix is here, although I have not tested it. I am waiting for CU7, or a chrome update.

Hi Mike

Thanks for the link. I hadn't found that one!

The good news is that it does fix Chrome on PC, unfortunately the bad news is it doesn't help iOS, which still has the problem.

OK, what's weird is that occasionally on a refresh it works in iOS.

We do have two servers in a DAG and using round-robin for the CAS, but I have updated both servers so am unsure as to what could be causing the issue.

I removed one of the DNS entries for the CAS to see if one of the CAS servers was at fault, but the same issue happened intermittently.  Refresh, calendar entries are there, refresh again, they're gone!

This does seem to be a bit of a mystery....

The fix I used was to add his mailbox to the iPad Mail app for iOS 8.0.2.  Works like a charm then.

Unfortunately it's not an option as we would require enforcement of policy on any devices that aren't online web access only.

The iOS devices all belong to end users (their personal devices) so we don't want to enforce policy on people's own devices.

A good in-between option would be OWA for devices, but that seems very flaky on iOS 8 and above too (from both experience and reading around!)

Have you thought about using the OWA application for iOS?  It is actually a great app and should allow for management but not required enrollment. 

OWA for iPhone/iPad

Yes we have, that's what our initial problem was with (check the first post).

The more I think about it, based on not hearing of too many people with the same problem, it would seem a later CU than we have installed may help....

OK, having updated Exchange 2013 to the latest CU we still have problems.

Since this (I think there was also an OWA for iPad update) the OWA for iPad app seems to work better, but can be sluggish and sometimes won't allow you to view individual emails (this has been reported by one of our users testing at present).

OWA in Safari seems to be pretty unusable.  I will need to clarify the issues.

I think I have similar issues with regards to OWA on iOS Safari browser. I haven't noticed the calendar problem but some users have problems viewing emails or replying/forwarding. When clicking on a single email, the new page is a blank page which is the same thing when replying or viewing. Sometimes loading up OWA before hand for a few minutes helps but that is not something that is always doable.
