If a Microsoft Exchange Server 2007 Hub Transport server processes a single occurrence of a recurring meeting that has the AppointmentRecurrenceBlob property set, the EdgeTransport.exe (Microsoft Exchange Transport service) process on the server crashes. The expected behavior is that the Exchange Transport service handles the problem and continues to run.

Additionally, the following events are logged in the Application log:

Time: Time
ID: 10003
Level: Error
Source: MSExchangeTransport
Machine: Computer
Message: The transport process failed during message processing with the following call stack: System.InvalidOperationException: Property AppointmentRecurrenceBlob is not permitted on meeting occurrences.

Time: Time
ID: 4999
Level: Error
Source: MSExchange Common
Machine: Computer
Message: Watson report about to be sent to dw20.exe for process id: Process ID, with parameters: E12, Build Type, Version Number, edgetransport, M.E.D.Storage, M.E.D.S.OccurrencePropertyBag.InternalSetValidatedStoreProperty, System.InvalidOperationException, XXXX, Version Number. ErrorReportingEnabled: False


This issue occurs because single-occurrence meeting requests do not support the AppointmentRecurrenceBlob property. Therefore, an InvalidOperationException exception is thrown that causes the EdgeTransport.exe process to crash.


To resolve this issue, install the following update rollup:
2746157 Description of Update Rollup 9 for Exchange Server 2007 Service Pack 3


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
