I am facing the same problem have you find a solution on your side ?
We have :
_ exchange 2010 SP2
_ ios 5 devices
The user has 2 ios devices : on one device (iphone) the meeting is present not on the other one (ipad). There is no "logic" in the missing meetings.
The user has a delegation on his calendar and the delegate accept the last meeting which was missing on the iPad.
Any update on your end? The official response from Microsoft is that they have had numerous teams working on the issues and have confirmed it's an IOS problem, not exchange. Microsoft said they have been in contact with Apple and Apple has confirmed they do know of the problem and are working towards a solution. I am trying to open a ticket with Apple at well to attempt to get a work around for interm fix.
Yes - some updates:
I can cofirm the commitment of Microsoft - they also have an open Case with Apple in US. We also have an open Case at Apple and they also confirmed it would be an iOS/Apple Issue. The Engineers of Apple are actively investigating the issue and working toward a resolution. Apple added the impact from our organization to this issue - I think as more iOS Devices are affected as more important will the case become important (until now I think it's a bit too low prioritiy) - so if other enterprises would open a case it would be helpful for all organizations.
As a temporary work around, when the issue occurs, the user can toggle calendar syncing off and then on. This should result in the calendar fully resyncing, and correctly showing all events. Depending on the amount of calendar data to sync, this may take a while to complete.

Is it anywhere on the Microsoft website or the Apple any information regarding this issue ? Just to let know my boss there is nothing I can do to help the end user except telling him to resync from times to times his calendar. I would be more than happy to tell Apple this is an issue for our users.
thanks for the update.
Well this is good news they we are hopefully moving in the right direction to get this solved. I tried opening a case by calling the support number on the apple website but I didn't get very far. Do you have another phone number or contact method that I could call to open a case higher up?
We have around 50 ipads and iphones that our staff both carry. They do not have issues with Exchange 2010 with Calendar syncing. The thing we have noticed is staff put appointments on the wrong calendars. iCloud vs the Exchange so they think it isn't syncing. So make sure you have them on the right calendars.
We have many users as well and most do work fine. There are a few exceptions and the problems seem to stem from users that have many appointments and that are constantly changing. These users also have a delegate that do most of the scheduling. The calendar meetings show up correctly in outlook and OWA but every few weeks a random meeting will go missing off an IOS device and still shows up correctly in outlook and OWA. So it isn't an entry mistake it is a random missing entry on the IOS devices.
I have finally found a solution to our problem here.
Exch 2003 SP2 Clustered
Installed and ran all of the MS patches and followed the Poof your calendar doc, still no go. Finally found and downloaded the Calcheck utility here:
Found all of the corrupted calendar items in the affected users mailboxes, and once removed, viola!!!!! full syncing between Iphone and Exchange Calendar. I had a user with one corrupted re-occuring appt. that was the culprit. Moved the appt out to a test .pst and syncing works 100%. Moved the appt. back into the calendar, syncing only 30% of the calendar.
Hope this helps
Hi at all,
thanks for all your tipps and tricks... but: everything as mentionned we already tested - synching right calendar towards exchange (so no private calendar as standard calendar); calcheck utility - didn't helped at our company.
We tested a lot and investigate also a lot of time in all these things... it seems really that it is an apple issue - we have some statements concerning this - but apple can't tell us when this issue will be fixed.
Microsoft also wrote a KB article http://support.microsoft.com/kb/2563324
or in english: http://support.microsoft.com/kb/2563324/en-us?fr=1
Maybe this will help for you?
I remember we meet the same problem (some appointment seem to vanish from the calendar (not recurrent one) ? and I can't see our problem in this KB
I remember seeing previously your company has been addressed Microsoft for the calendar issue : is it the KB you have been furnished by Microsoft or is there an another one ?
