I tried setting a few properties on this object to send an email with high importance, but nothing seemed to work. Here is what I tried:
objEmail.Importance = 2
objEmail.Configuration.Fields.Item("urn:schemas:mailheader:X-MSMail-Priority") = "High" ' For Outlook 2003
objEmail.Configuration.Fields.Item("urn:schemas:mailheader:X-Priority") = 2 ' For Outlook 2003 also
objEmail.Configuration.Fields.Item("urn:schemas:httpmail:importance") = 2
Function Send(sTo As String, sFrom As String, sSubject As String)
Set objEmail = CreateObject("CDO.Message")
objEmail.From = sFrom
objEmail.To = sTo
objEmail.Subject = sSubject
objEmail.Textbody = emailBody
objEmail.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "my.smtp.server"
objEmail.Configuration.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
// is there a property for high importance, outlook 2007?
objEmail.Configuration.Fields.Update
objEmail.Send
End Function
