This problem occurs if the following conditions are true:

�	You have a mailbox that is located on a Microsoft Exchange Server 2007 mailbox server.
�	You receive a recurring meeting request from a user who has a mailbox that is located on an Exchange 2003 mailbox server.
�	The user who sent you the recurring meeting request updates the meeting request to remove the recurrence. Then, the user resends the meeting request.

To work around this problem, have the user who sent the meeting request cancel the meeting request. Then, have this user send a new meeting request that has only a single occurrence.
