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

You might be right - after testing with a new recurring meeting it did seem to recognize the exceptions. Existing recurring appointments that were changed didn't get fixed.

I suppose the question is do we (my admin and I) need to recreate all the current recurring appointments in order to "future proof" them?

Mar 10, 2015 2:24 PM in response to Mandingo2010

So the issue is not with the whole series at all (from my experience), it is only with the exceptions to the series (when you move a meeting...and even then, it only stopped updating when we moved an occurrence of the meeting more than once). The first move was updated on the phone, but if we had to move that occurrence again, each subsequent move was not processed by active sync.

If you cancel the reoccurring meeting and recreate it, you will lose any changes to that series anyway. I would say just look through the series and if there are any changes to the series, then just make a change on that occurrence forcing active sync to see the change and push that item back down to the phone.

On a side note, I also tried to remove my calendar from my phone all together and just re-sync all appointments, but that did not work. The meetings that were messed up before still synced to the wrong date/time until I forced a change.

Hi all, how is everyone finding this issue since the iOS 8.2 release? We have performed some testing in our IT department but our calendars are nowhere near as populated as the people who are experiencing it. Before we put iOS 8.2 forward as the solution we just want to be as sure as we can be that Apple have now resolved this.

Any feedback would be appreciated.

This is easy to reproduce Greeryofoffy. If you have iOS 8.0 or 8.1 (I believe this was not an issue in iOS 6.x or 7.x), then just create a reoccurring meeting from Outlook. Move one of the occurrences and check your phone, it should have the updated time. Move that same meeting again and this should not update on the phone. After you update to iOS 8.2 the meeting will NOT automatically correct itself. You will have to move that meeting to force an update, then it should be updating on your phone. Good luck.

Seems better in 8.2 but I am still having issues.

A recurring appointment for today was canceled by my Admin but it still showed up on my calendar.

If I do the old workaround (disable Calendar then re-enable it in Settings) then all the appointments show correctly after a sync.

Kind of frustrating to have to resort to OWA or this workaround to get an accurate copy of my Exchange calendar.

My calendar entries on iphone are not syncing to my outlook. This may be a different challenge for some of you. Has anyone experienced a fix to this that you can recommend?

In my Exchange 2010 environment an iPhone 6 with iOS 8.1 was having this issue with Exchange calendar items (recurring and non-recurring) not appearing on the iPhone. We updated the iPhone to 8.2 with a very specific process:

Remove the Exchange account from the iPhone 6 with 8.1 still installed. Reboot.
Update the iPhone 6 to iOS 8.2. Reboot.
Add the Exchange account to the iPhone 6 with 8.2 installed.

The problem persists. Reviewing 4 weeks of calendar items from OWA I found 10 appointments that were in Exchange but not on the iPhone.

My next troubleshooting steps will be to add the Exchange account to an iPhone with iOS 8.2 on which the account never appeared before. Then I'll see if this issue persists. Has anyone ever tested this?

Mar 19, 2015 3:42 PM in response to TheGoz

So if you disable the calendar on the phone (Settings - Mail, Contacts, Calendar - Account - slide Calendars to OFF) then re-enable it the calendar still looks different from Exchange?

When I do this on 8.2 the calendar syncs 100% correctly. It is when certain *individual recurring items* are moved/deleted that the problem appears for me.

Following up on my original post about planned Factory Reset, upgrade, adding Exchange Account. This completely resolved the issue of missing calendar items. Since upgrading the device, deleting all iPhone data and factory resetting the device, then setting it up again and adding the Exchange Account we have not had lost and missing calendar items.

To all,

I noticed this issue as well, Exchange 2010 environment, iPhone 5s, iOS 8.3(12F70). I created a recurring appointment 2 weeks ago in Outlook 2013 (well after the iOS 8.3 update), and it disappeared at some point in the last week from my iPhone. Still there in Outlook. I don't know when it disappeared, I just happened to notice it this weekend. It was really annoying because I had just created it recently.

Long story short, the Settings->Mail...Calendar, disable then re-enable process for my Exchange worked for me.

Thanks to all who suggested it, good luck for those still experiencing it, and hopefully Apple and Microsoft commit to resolving it. Doesn't matter whose fault it is, bad business for both companies and it's in everyone's best interest to fix it asap. Let's hope someone is listening.

Best,

Rob

Nice one Netwalker!!! Manual workaround still works (and still required) on 8.4.1. Not sure if fixed in iOS9 although will be upgrading in any case.

Thanks so much. That worked for me too. I only have issues with my iPhone, not my iPad. I'm on IOS 9.0.2 so it still exists on latest version. Come on Apple fix it!

This bug is still not fixed in iOS 9.1

I am the exchange administrator for our company, in my own calendar there was a daily recurring appointment which disappeared from my phone.

Disabling the option to sync the calendar and enabling it again did not resolve the issue.

The appointment in question synced fine to Android, Exchange Server 2010 is fully patched.

To resolve it, i had to delete the recurring appointment from the calendar and recreate it, now it synced to the device without issue.

The issue is that i was not the meeting organizer so i wouldn't get any future updates to the appointment.

There is no indication as to why this appointment would not sync to the device, since it syncs to other mobile devices i'd need to attribute it to a bug in iOS.

It actually worked! Thank you. I guess I'll just have to follow this procedure every time I enter a recurring appointment. Hope Apple fixes it soon.

How the **** is this still a problem? Why has this been allowed to languish and persist for so long?? I've been on board with the iPhone since the 3G model. I just can't imagine that Apple would be so intent on ignoring enterprise oriented bugs like this.
