Using the MAPI control in VB6, I can do all the things correctly, however 
there is no 'Sent Date' on the outgoing emails. If I open the Outlook 
client on the machine for that user profile and send an email there is 
a 'Sent Date', it's only when sending through the VB app that I have no 
joy. The other geeks around here, like me, believe that this issue is with 
the MAPI control, not with the Exchange Server or the user Profile. This 
hasn't been a problem (or even known about) until we upgraded the app that 
the emails were being sent to, now it has a wobbly and won't accept the 
emails I'm sending to it... Any help would be greatly appreciated.
