The Edgetransport.exe process crashes when it processes meeting requests in Exchange Server 2007

On a Microsoft Exchange Server 2007 server, the Edgetransport.exe process may crash when it processes a meeting request. This problem occurs when the following conditions are true:

• The regional setting of the local computer is set to Arabic.
• The Calendar type of the local computer is set to the UmAlquraCalendar class.
  Note Generally, the default Calendar type is set to the UmAlquraCalendar class.

Additionally, the following event is logged in the Application event log:

This problem occurs if the DateTime property of the meeting request has no year data. In this case, when Exchange Server 2007 processes the meeting request, it sets the DateTime property of the meeting request to "1/1/1600". However, the Arabic regional setting only supports aDateTime range between 04/30/1900 and 05/13/2029. Therefore, the ArgumentOutOfRangeException exception occurs, causing the Microsoft Exchange Transport Service process crash.

To resolve this problem, install the following update rollup:

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