Don't know why it's doing this way, but I might know a solution to your 

problem.. Have you tried putting the working VB code in a Com object and 

then call the function in the Com? 



You wrote that the code ran under a user with access to all mailboxes.. 

a.k.a a superuser.. Could you perhaps help me to create a superuser in 

Exchange 5.5?
