I have developed a Exchange 2003 Managed Async sink using the Onsave event.
My problem is that I cannot get the sink to run correctly without Microsoft
visual studio 2003 installed on the Exchange server.

What happens is that the sink is executing as expected without VS 2003 if I
do not open an ADO connection the message. But if I open a connection
anywhere in the code it does not run at all.

public void    OnSave(Exoledb.IExStoreEventInfo pEventInfo, string    bstrURLItem,
int Flags)

{
            log("Start","Start"); /// write a log entry to a file
}
The above works, while this below does not execute at all (But the code is
loaded by com+  as  the dll files are locked as soon as the event is
triggered):

public void    OnSave(Exoledb.IExStoreEventInfo pEventInfo, string    bstrURLItem,
int lFlags)
{
CDO.IMessage Message = new CDO.MessageClass();
             log("Start","Start"); /// Should write  a log entry to a file
but dos not when a ADODB connection is made any where in the code without VS
2003 install.
    System.thread.Sleep(10000); // I added this line to make sure it had the
time to close the log file but no out put at all.
Try
{
    Message.DataSource.Open(bstrURLItem,null,ADODB.ConnectModeEnum.adModeRead,ADODB.RecordCreateOptionsEnum.adFailIfNotExists,ADODB.RecordOpenOptionsEnum.adOpenSource,"","");
}
Catch(Exception e)
{
    Log(“Could not read file”,e.Message); // This is never executed either.
}
}

I have signed all interop assemblies,Sink dll and registered the sink dll as
a com+ service. I do not have to recompile the code or rereg with com on
server just install VS2003 to get it to work.

Any ideas why this is not running without visual studio installed?
