It has been discovered that a bug in iOS 6 affects Microsoft Exchange meeting invitations to such extent that the service becomes completely unreliable. At least one Fortune 500 company has acknowledged the flaw and is now advising employees to stay away from iOS 6.
An “Information Technology Notice” was sent out this week to employees in an unnamed organization listed by Fortune 500 with information regarding a bug that could severely affect operations.
The memo, addressed to “mobile device users who connect personal Apple mobile devices (iPhone, iPad, etc) with company email,” states that “on September 27, IT notified you of an intermittent issue caused when calendar appointments are declined from devices running the latest Apple operating system (iOS 6).”
“Apple and Microsoft are providing IT with daily updates on their progress toward a resolution,” it says.
The company then proceeds to detail the nature of the bug, stating that “When appointments are declined from an Apple mobile device running iOS 6, a cancellation is sometimes sent to all meeting attendees instead of sending a decline notice to the meeting organizer.”
At least two forum threads
on Apple Support Communities
are actively discussing the bug, confirming the issue as widespread.
The memo sent out by the company in question includes a warning against upgrading to the latest version of Apple’s mobile operating system.
“Action to take: Do not upgrade your Apple mobile device to iOS 6. If you have an iPhone 5 or have already upgraded a device to iOS 6, please do not accept or decline calendar appointments from your Apple device until further notice,” reads the snippet.MacRumors reports
that several affected companies are already talking to Apple and Microsoft about the bug, as well as another one causing push delivery of emails to fail.
