Microsoft.Office.Interop.Outlook error message

[AvivMalka]

We have .Net COM. It is developed in VB.Net. It's used in an application that stores mails from Outlook 2007 in MS SQL Server Database.​

While using it in an application on WINDOWS Server 2008 R2 we get exception:

This code is working on Widows XP SP3 without any error.
Microsoft.Office.Interop.Outlook RuntimeVersion v1.1.4322.
The code is failing after more then 2 calls.
Last 2 actions in Outlook before calling SetSelectedMailM function are Delete Mail, Activate OutlookExplorer.
We got this problem after migrating to new remote terminal server.
Help me understand what is the problem, please.

Forward event handler is not exist in my code
