Fortune 500 Company Urging Employees Not to Upgrade to iOS 6 Over Exchange Bug - Mac Rumors:
MacRumors has learned that at least one Fortune 500 company is requesting that its employees not upgrade to iOS 6 over a bug with Microsoft Exchange meeting invitations. The issue has also been reported on Apple's support discussion boards.

The issue appears when users decline a meeting invitation from an iOS 6 device. Instead of simply sending a notification to the meeting organizer that the user will not attend, iOS 6 is sending meeting cancellation notices to the entire distribution list, effectively canceling the invitation for all attendees.
