Earlier this week I recieved the cancellation message below for a bi-weekly management meeting a number of us have in our calendar. The intent from the sender was just to cancel the Nov 8 meeting. However, it removed all management meetings (past and future) from my calendar. It didn't do so for the other recipients. I also use an iPhone synced to the Exchange server.
This has happened a few times before and we've had to re-enter the meetings into my calendar. Can you think of any explanation?
