Is anyone else seeing this issue???

 

About a week ago we started receiving reports from our executive assistants in regards to strange Outlook calendaring behavior where meeting cancellations were being sent out, but not from the meeting organizer, but one of the meeting attendees. A few details:

 

  1. The meeting cancellations from the attendee (let's call this person User B) has confirmed they were not in their Outlook calendar, nor were they modifying any calendar related events from their PC or their iDevice(s).
  2. User A (the original meeting organizer) does not receive the meeting cancellation notice, but all other attendees do.
  3. When the cancellations are mistakenly sent out from User B, MULTIPLE cancellations are sent, meaning there are literally 10-20 cancellations sent for the same meeting.

 

We're running Exchange 2010 SP2 with Outlook 2010.

 

These reports seem to have started with the release date of the iOS6 update.

 

We have not patched Exchange/Outlook recently nor have made any other changes to the environment.

 

I have a case open with MS Support and am waiting for a call back.

 

Anyone else seeing this??? I searched the Apple Support forums but wasn't seeing this exact issue.

    I am having the exact same issues as you decribe and it driving me nuts. We are still running Exchange 2003.  The only thing that I have been able to conlude is that when these meeting cancellations come through it is coming from a recipient and so far all have had iPhone's with iOS 6 and they say the same thing that they didn't even accept or decline the meeting.  This is causing great frustration from our executives and board members.  We need some help with this issue very badly.

     

    I worked on this issue all day Friday with our CEO because the meeting cancellations were coming from him.  He did have his calendar syncing to iCloud along with exchange. I turned off syncing of just his calendar to iCloud and this seemed to help but it I am not 100% sure yet.  But the problem is that we are seing cancellation coming from board members and other meeting recipients outside our orginazation.  I look forward to others commenting on this issue.

    While I cannot help with this issue, I have responded to another post I found earlier today and these two threads may be of help to each other. Try responding to one of the posters on this other thread https://discussions.apple.com/message/19821576#19821576

    Thank you.  I found another thread here as well https://discussions.apple.com/message/19749607#19749607  I think as more users upgrade to iOS 6 this is going to be a huge issue.  Apple better get out in front of this and fast.

    I looked at the email headers of one of the canellations of one of the recipients of the meeting request.  The email came back that he cancelled the meeting even though he was only a recipient.  This was in the header:

     

    Content-Type: text/calendar;

              method=CANCEL;

              name="meeting.ics"

    Content-Transfer-Encoding: 8bit

     

    This may be a clue to what is going on.  The iPhone is sending back a cancel reqest for whatever reason even though the end user had not even looked at the appointment.

    Thanks for the update.  I am just not sure how this is a Microsoft problem since it all started with the iOS 6 upgrade.

    Can I ask what the exact steps are to replicate the issue? I've been trying to reproduce it with no success.

     

    Are you opening the invitation in Calendar or in Mail? Is it invitations sent to individuals or to distribution groups? What version of Exchange is everyone running?

     

    Here is what I'm running:

    • Exchange 2010 SP2 RU3 (v14.2 Build 247.5)
    • iOS 6.0 for iPhone & iPad
  • Jessica Cochran Calculating status...

    We are seeing the same issue in our environment as well. Exchange 2010 Sp1 windows server 2008 R2

     

    We have seen miscellaneous issues when users accept meetings or decline meetings on their IOS devices since we started using them.

     

    If anyone has any suggestions, would really appreciate them.

     

    Thanks

    The ones that are reporting this issue with the decling meetings are running IO6. The large majority of our iPhone/iPad users updated to IOS 6 the day it was released.

     

    Many of them already have iPhone 5's as well.

    Same issue here as well, I replied to the other post linked in this thread, what a mess.
