Meeting in attendee’s Calendar loses track of the meeting organizer
Article ID: 2768774 - View products that this article applies to.
Microsoft is aware of an increase in the number of issues that are related to meeting requests. This increase in the number of issues coincided with the release of Apple iOS 6 devices. In these issues, users who are attendees of a meeting may unintentionally become the meeting organizer.
When this issue occurs, the organizer information is not changed when you view the item in Microsoft Outlook and Outlook Web App (OWA). If an attendee takes action on a meeting item by using an Apple iOS 6 device and then synchronizes with Microsoft Exchange Server by using Microsoft Exchange ActiveSync (EAS), the meeting attendee may become the meeting organizer.
Additionally, the Apple iOS 6 device may incorrectly let the device user (attendee) act as the meeting organizer. For example, the attendee can send meeting updates or cancellations to all the original meeting attendees.
This issue can affect users of Microsoft Exchange Server 2010, Microsoft Exchange Server 2007, and Microsoft Exchange Server 2003.
Note This issue has been fixed in Microsoft Exchange Online for Office 365.
This issue was investigated by Microsoft and Apple. Apple recently released the iOS 6.0.1 Software Update. This update is intended to address the issues that were reported by customers.
Note For more information about this iOS 6 update, see the "Resolution" section.
Note This article will be updated with additional information when the information is available.
Note This issue is not the same issue that was fixed in Exchange Server 2007 Service Pack 3 (SP3) Update Rollup 4 (RU4). The issue that was fixed in Exchange Server 2007 SP3 RU4 is documented in the following article in the Microsoft Knowledge Base:

Install the most recent iOS update
Apple has released the iOS 6.0.1 Software Update. This update is intended to fix several issues. This includes a bug that affects Exchange meetings and applies to Microsoft Exchange Server 2010, Microsoft Exchange Server 2007, and Microsoft Exchange Server 2003. However, because of a meeting response issue on the device, we recommend that you install the iOS 6.1.2 Software Update or the most recent update that is available.
If you cannot install Exchange Server 2010 Service Pack 3 or update devices to iOS 6.1.2,, use one or more of the following methods:
