Microsoft is aware of an increase in the number of incidents that are related to meeting requests. This increase coincided with the release of Apple iOS 6 devices. In these incidents, 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 a meeting 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 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 2013, 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 and in Exchange Server 2013 Cumulative Update 1 (CU1).
This issue was investigated by Microsoft and Apple. Apple released the iOS 6.0.1 Software Update that was intended to address the issues that were reported by customers.
