Apple have released an update to iOS which, amongst other things, address an issue with Microsoft Exchange meetings.
The issue revolved around iOS incorrectly assuming an attendee at a meeting was the organiser. The meant any changes the attendee made to a meeting using their iOS device (iPhone, iPad) were automatically accepted, leading to situations where meetings were cancelled automatically for every attendee or times changed without the organiser being aware.
Microsoft published an advisory notice about the issue, listing the symptoms:
“Microsoft is aware of an increase in issues for meeting requests that coincided with the release of Apple iOS 6 devices. When this occurs, users that are attendees of a meeting may inadvertently become the meeting organizer.</p><p>“The organizer information in Microsoft Outlook and Outlook Web App (OWA) is not changed in this scenario. If an attendee takes action on a meeting item using an Apple iOS 6 device, synchronizing with Microsoft Exchange Server using Exchange ActiveSync (EAS), the meeting organizer may be changed and replaced by the attendee.
“As a secondary result, the device may incorrectly assume that the device user (attendee) is the organizer, and can send meeting updates or cancellations to all of the original meeting attendees, as if the mailbox user is the organizer.”
The Apple software update is a recommended download, and is available through your iOS devices General settings option.
