NameSpace.AutoDiscoverXml is an XML string that is returned from the auto-discovery service of the Exchange server. The following code sample uses the AutoDiscoverConnectionMode property to show when this XML string is available during a normal Outlook session.

  • When the Application.Startup event occurs, if AutoDiscoverConnectionMode is not equal to olAutoDiscoverConnectionUnknown.

  • When the NameSpace.AutoDiscoverComplete event occurs, if AutoDiscoverConnectionMode is not equal to olAutoDiscoverConnectionUnknown.

Dim WithEvents Session As NameSpace 
Dim LastAutoDiscoverXml As String 
Dim LastAutoDiscoverConnectionMode As OlAutoDiscoverConnectionMode 
Private Sub Application_Startup() 
 Set Session = Application.Session 
 If (Session.AutoDiscoverConnectionMode <> olAutoDiscoverConnectionUnknown) Then 
 LastAutoDiscoverXml = Session.AutoDiscoverXml 
 LastAutoDiscoverConnectionMode = Session.AutoDiscoverConnectionMode 
 End If 
End Sub 
Private Sub Session_AutoDiscoverComplete() 
 LastAutoDiscoverXml = Session.AutoDiscoverXml 
 LastAutoDiscoverConnectionMode = Session.AutoDiscoverConnectionMode 
 If LastAutoDiscoverConnectionMode <> olAutoDiscoverConnectionUnknown Then 
 End If 
End Sub 
Private Sub DoAutoDiscoverBasedWork() 
 ' Do activity requires auto discover information 
 Dim displayName As String 
 Dim posStartTag, posEndTag As Integer 
 posStartTag = InStr(1, LastAutoDiscoverXml, "<DisplayName>") 
 posEndTag = InStr(1, LastAutoDiscoverXml, "</DisplayName>") 
 If (posStartTag > 1 And posEndTag > 1) Then 
 displayName = Mid(LastAutoDiscoverXml, posStartTag + 13, posEndTag - posStartTag - 13) 
 Debug.Print "DisplayName = " & displayName 
 End If 
End Sub
