[RESOLVED] Sending emails in Win7 gives me error 48389

[Spajder]

I've got it!

somehow, if I'm sending email with mapi from Outlook to someones email address, his email address loses his E-mail type. If I click into Sent items, search my email, sent from my vb6 application, and make a right click on recipients email address and choose Outlook Properties, I would see his E-mail type like the one in the left picture. And this was wrong!

Here is the example from my solution:

If MAPISession1.SessionID <> 0 Then
   MAPISession1.SignOff
End If
MAPISession1.SignOn
MAPIMessages1.SessionID = MAPISession1.SessionID
MAPIMessages1.Compose

MAPIMessages1.RecipAddress = "smtp: [email protected]"
MAPIMessages1.RecipDisplayName = "smtp: [email protected]"
MAPIMessages1.AddressResolveUI = True

MAPIMessages1.MsgSubject = "My email with attachment"
MAPIMessages1.AttachmentPathName = Path & "\" & name
MAPIMessages1.MsgNoteText = "Hi there. " & Chr(10) _
     & "Here are some pgp files for you!"
MAPIMessages1.send False 
If MAPISession1.SessionID <> 0 Then
   MAPISession1.SignOff
Else
   MsgBox "This email could not be send to recipient!"
End If

I have removed the line with MAPIMessages1.ResolveName and have added "smtp:" to MAPIMessages1.RecipAddress and have done the same with MAPIMessages1.RecipDisplayName. I have also added MAPIMessages1.AddressResolveUI = True

With this code I can send email with attachment without any error!
If I would now check Outlook properties, the email type would be now correct (see the right picture).

So this problem is solved. But now I have another problem (please see the new thread, because this thread is resolved).
Some of recipients emailed back to me, telling me, that email attachments (like file.pgp) are in wrong format or the files are not attached at all. Some of them have had attached this file: Winmail.Dat.

How could this be? Have I missed something??? I suspect Outlook for this weird behavior.
Can someone help me please?

Thank you
