    I had this problem since upgrading to iOS 6 and recently changed the time zone setting (Settings/Mail,Contacts,Calendars/Calendars...Time Zone Support) which was off by default.


    For some reason invitees has since been available on new calendar entries.


    Hope it works for you.

    That worked for me too. You just have to remember this when traveling, because all your events will show at the time of the time zone you choose in the settings.

    Worked for me too wwwired!  Thanks!  (My wife wasn't very happy with me after updating her phone to iOS6 just for this reason.)

    New IOS 6.0.1 update 11/2/12 fixes this problem. You can set time zone support back off and invitations work fine.

    I have a fix for my situation which may be similar to yours.  My exchange account is my apple id and my default mail/contact/calendar.  Many calendar invitations were not being sent and if they were, I was not receiving responses in the event...  I found a setting for "Automatic Calendar Processing" in the "web access" for my exchange account.  Capture.JPG

    The moment I made the changes shown in the attached picture, my current and previous meeting requests updated.


    Hope this helps someone else...

    My issue is in line with this posting, but with a major variation: Executive Assistants are managing the calendars for both themselves and the executives they support. I'm faced with a primary Exchange email / calendar account on an iPhone 4 AND a secondary Exchange email / calendar account on the same device.  The secretaries manage every block of time for their respective President or Vice President and keep both their own Exchange calendar as well as their fellow's.


    When a Calendar event is created or accepted in Outlook on a Windows 7 PC, it is done by the secretary.  Yet the invitation is still sent to their respective iPhone 5 and iPad devices as unanswered.  Whether accepted or declined, the invitation still shows in their Calendar Invitation "inbox."  This is affecting the devices of everyone involved.  It is as if the invitation activity (Accept, Decline or Tentative) is not being handled or processed by the Apple OS.  On the secretarys' phones, it appears that since their calendar is the default, it handles the invitations properly (with few exceptions).  However, the calendar for the secondary mail account, which is the executive's, is not processing the invitations as handled originally in Outlook (accepted, declined or marked as tentative).  The invitations are still showing on the executives' phones as needing a response though their secretaries booked the event through Outlook.


    I was told that it worked "perfectly" with the iPhone 4 and iOS 5, and suddenly "broke" when going to the iPhone 5 and iOS 6.  I have tried every combination of software switches and setting available on the phone. I did find that if I went to Settings \ Mail, Contacts, Calendars \Exchange account(s) and turned the calendar OFF for the respective account, deleted the Exchange Active Sync information, then turned it back on to re-download the current calendar information for that mail account, they're good until the invitations begin to accumulate to a value that bothers them.


    What I have tried:  made sure the Executive Assistants had the highest permissions on the Outlook accounts for their respective Executive.  I have encouraged them to answer each calendar item with Accept, Decline, Tentative and to make sure they select Send Response Now (perhaps this was the trigger?).  I have removed Exchange mail accounts and recreated Exchange mail accounts on each device.  Each device is updated with the latest iOS. I have turned off New Calendar Alerts on the iOS.  I have turned off Shared Calendar Alerts.  Time Zone Support is off.  We are using Exchange 2010 and Outlook 2010.  I feel like I have scoured support forums for Apple and Exchange / Outlook and came across several with similar situations (mine is the only scenerio I know of where the secretaries are managing the calendars for others).


    As an IT Professional, I am only as good and accomplished as my last solution.  This particular issue has the powers-that-be question my competance (what?!?  You don't know both Server OSes, Windows 7 and Apple?!)  Any suggestions, tips, tricks or prayers would be appreciated.

    I would suggest you complain directly to Apple on behalf of your company. They are being very slow with OS updates to fix these things. There are several threads like this on this site.


    Although I think your situation is a complicated one, I think other companies might have the same setup.


    Just one other suggestion. Don't say "secretaries and their fellows". Sounds kind of 50's and sexist.
