Hi,

i've programmed an addin in VB6 which is sending mail from our CRM
system automatically.

The addin works fine, that means that it's doing what I want it to do.

When the addin is installed on a system with outlook 2000 (SMTP/POP3)
the attachment arrives at the recipient correct but when outlook 2003
(SMTP/POP3) is installed, the attachment is sent as winmail.dat and of
course some systems are not able to open it.

When the addin is installed on a system with outlook 2003 in
combination with Exchange 2000/2003 the attachment is correct again.

Here is an example of my code:
---------------------------------------------------------------------------------------------------------
Set olMsg = m_olApp.CreateItem(olMailItem)
olMsg.Subject = ls_Subject

olMsg.To = ls_Name + "" + ls_Address + ""
olMsg.Body = m_sMailBody + vbNewLine + vbNewLine

If Left(m_olApp.Version, 2) = "11" Then
olMsg.BodyFormat = 1 'PlainText
End If

olMsg.Save
olMsg.Attachments.Add ls_FileName, olByValue, Len(olMsg.Body) - 1

olMsg.Send
---------------------------------------------------------------------------------------------------------

Thanks a lot for your help and answers.
