Consider the following scenario. In Microsoft Office Outlook 2007, a delegate accepts a meeting cancellation on behalf of a manager in the delegate's own Inbox. The meeting is removed from the manager's calendar. However, if a second delegate then opens that meeting cancellation in his or her own Inbox, the canceled meeting is added back to the manager's calendar. In this scenario, the subject of the canceled meeting is displayed as "Canceled: subject" in the manager's calendar.
To resolve this problem, follow these steps:
Install the following hotfix package:
