C# Outlook Object Model / Exchange 2003 Event 9646

[fb]

I don't see an Exchange specific newsgroup so I am posting this here

Problem
Exchange Server throwing Event ID: 9646 'exceeded the maximum of 250 objects of type "objtMessage"

Cause
Application using C# Outlook Object Model is enumerating through calendar items to provide synchronization with an external calendar. The items can exceed well over 250 objects

Question:
How do tools like Mailbox Move and ExMerge get around the limitation? Is there a way to create an exception to the rule based upon the user or application (digital signing)?
I have seen kb830836 and others. Modifying the registry to increase the number of objects allowed to be accessed is not desirable. I would prefer to find a way to allow the application to work (as it did with Exchange 2000) without disabling / altering the settings across the board

Thanks!

fb,
Are you calling System.Runtime.InteropServices.Marshal.ReleaseComO bject when
you are done with each COM object?

For a list of articles on using Outlook form .NET see:

Hope this helps
