Recurring Meetings show in Exchange Calendar, but not on iPhone iOS 6.0.1

We have an Exchange 2010 environment, with users on iPhone 4S iOS 6.0.1

A user creates a recurring appointment in Exchange, and some of the attendee's can see the appointment on their Exchange Calendar on their laptops, but not on their iPhones. Other appointments do show on the iPhone. In some cases, the attendee also has an iPad iOS 6.0.1 as well, and they can see the appointment on the PC and iPad, but not their iPhone. I compared all settings between the iPad and iPhone, and they were the same.

I did some research online, and saw this: http://support.microsoft.com/kb/2563324 Which states:

Issue 1.7 - Meetings are missing due on some mobile devices, but are present in OWA and Outlook
When you create a recurring Appointment or Meeting, then change a critical property in an occurrence in the series (for example date, time or location), and then change the whole meeting Series again, the item may not be updated on a device.

The change is reflected correctly in Outlook, but meeting organizers or attendees do not see the change reflected on their devices. The result is an apparent "missing appointment" on the device user's Calendar.

Cause

The devices use the Global Object Identifier (GOID) instead of the ServerID to track changes to the Calendar item for synchronization requests.

When the meeting series is changed, the same GOID is retained on the whole series. When the device receives the Delete request, sent when the series is changed, in a separate sync request from the change to the individual occurrence, it considers the series change as a duplicate and does not process the update.

Solution

Microsoft believes this issue is resolved in iOS 6. For confirmation or further investigation of this issue, contact the device manufacturer.

This issue is NOT resolved in iOS 6.

I even tried to "Send Update" on the meeting, without any changes, to see if the meeting will show up on the iPhone. In some cases it did, yet other users it did not.

Does anyone have any ideas??

iPhone 4S, iOS 6

We have seen this problem on several iPhones as well. As anybody been able to make any headway with Apple?

Some or our users now print their calendar because too many recurring items would go missing.

Seems like "edited" recurring items are the worst cases.

Re-sync (stop sync and restart) makes the items re-appear.

We're desperate for a solution.

Can everyone who has an issue with this bug submit it to Apple?

If we can get enough noise on this hopefully it will move up their priority list.

I just submitted it:-

One more suggestion - until Apple fixes this, Microsoft's OWA native app for iPhone displays correct Exchange calendar information - not as feature rich as the built in Apple iOS calendar but it is at least 100% accurate:-

I created a bug report on this issue becaus whe are experiencing the same issue with a few customers. When they change/modify an appointment the calendar item on the iOS device will not update.

Yes, this is absolutely annoying. I have missed some critical meeting at work due to this bug. Meeting organizer changed the time of this meeting series, and the whole series is gone. Apple really need to step up and fix this. I am on 8.1.2 Iphone 6+

Jan 16, 2015 4:00 AM in response to hawkhai

Same problem here.

What bugs (..) me is that it doesn't occur all the time. I can't reproduce it. So there has to be another thing between Apple's iOS Mail app and the Exchange server that's causing appoinments to disappear or get corrupted.

anybody did some investigation in this area?? Could it be that the Exchange CAS server are too busy??

cheers

Same problem since about four months.

Sometimes changing an appointment it results update on the iphone where i have made the change but the changes doesn't arrive at Exchange server so the owa, Outlook and other iphone devices don't get the update. I have analyzed the connection between the iphone 6 ios 8.1.2 and Exchange server and i have found this:

When the meeting doesn't sync, I have found in the trace that the server reply with

<Status>6</Status>

</Change>

</Responses>

Microsoft says about ()https://msdn.microsoft.com/en-us/library/gg675457(v=exchg.80).aspx

Error in client/server conversion.

The client has sent a malformed or invalid item.

Item

Stop sending the item. This is not a transient condition.

Have you ever seen this?

I think it's probably connected to the reminders, in the item not synced I have <Reminder xmlns="Calendar:">-9</Reminder> created from iphone when you choose "Postpone" after the alert popup's

I'm going crazy. I have called the apple support and Microsoft support too. I'm still in contact with Microsoft support but apple doesn't reply anymore.

It's helpful that Apple write something about!

Updated to 8.1.3

Issue still present. I talked to the Apple Business Support and they told me to ask the "Apple Crossplatform Support", but you have to pay per incident and I think, they can't solve the problem anyway. So I won't hire them.

Is anyone experiencing this with Exchange 2013 or is everyone on previous versions? It has been mentioned to us that this issue may be resolved in Exchange 2013 but I am dubious, as far as I understand it this is an iOS issue rather than an Exchange one.

Feb 23, 2015 1:13 PM in response to greeryofoffy

This issue is not resolved in an Exchange 2013 environment. This is not an Exchange issue, it's an iOS Apple issue. We have Exchange 2013 and are seeing this happen on multiple iPhones. Part of the problem is, it doesn't happen all the time. When it does happen, it's when you change a meeting time/date. It will update in your Outlook program, but not on your iPhone. Very frustrating!

How sad to see this chain go back that far. I do have the same problem with an iPhone 6 Plus with iOS 8.1.3. It's very annoying and usually happens when rescheduling an ocurrence of a recurring calendar event from Outlook. The entry on the iPhone doesn't change and so I end up missing the appointment. The one fix I have been able to see is going into Settings and turning OFF the calendar under Mail, Contacts, Calendars (select the Exchange account and turn Calendar to OFF), then turning it back ON. It's a real pain in the rear and it usually takes three or four minutes to repopulate the iPhone. Can't believe this problem has been on-going for so long.

Mar 5, 2015 6:14 AM in response to walterchris

We've had this problem with the iPhones in our group (including mine) for over a year (so long ago that I don't recall exactly when it started). It's made the device useless for managing my schedule... and while I hate Android I've started telling my folks to go that route (or windows phone) due to the problem.

This is an embarrassment to Apple.

Apple has just released ios 8.2 and there is one interesting moment in release notes:

Addresses an issue that caused certain events in a custom reoccurring meeting to drop from Exchange calendar

Can someone check whether the bug is resolved?

Mar 10, 2015 12:49 PM in response to Kirjanov

Looks like it is still broken on 8.2

Mar 10, 2015 2:02 PM in response to Mandingo2010

It looks like it is actually fixed, however if you have an old meeting that was affected before the update (I found if a meeting was moved more than once the meeting would not show up on the right date/time), then that occurrence would need to be moved and then moved back (basically you need to force a change to that meeting). I did try to update and then check my calendar right after, but the meetings occurrences that were not updating did not just fix themselves. Once I moved the meeting, it now was updating on my phone just fine.
