Hi
We've experienced an issue mentioned in KB2563324:
"Issue 1.9 - An appointment does not update when you use Outlook in cached mode and room mailbox is an attendee
The following conditions cause an appointment not to update on an iOS device:
- Organizer is using Outlook in cached mode.
- A room mailbox is listed as an attendee
- Calendar processing for the room mailbox is set to AutoAccept
- Organizer makes a change to in an instance of a recurring meeting"
However our problem is that apart of the event not updating on the iPhone handsets we also see "Not current" event error in the MS Outlook so the recipient cannot accept or dismiss the update from MS Outlook client on the laptop. I believe that it happens because of the original cause from the KB:
"Cause (from KB2563324)
Exchange sends two responses for the appointment on the device that contain an exception for the appointment. The second response contains the updated time for the meeting. However, the time stamp for the appointment is older that the first response."
That would explain the MS Outlook error on the workstation saying "Message out of date" and "Not current" event.
Unfortunately the KB2563324 isn't clear if this issue could also affect the same user account in MS Outlook client.
I've also found that this problem is only affecting users with Outlook Anywhere so I wonder if problem mentioned in paragraph 1.9 in KB2563324 would affect both the iPad calendar and same calendar in MS Outlook 2010 using Outlook Anywhere?
Could you please advise.
