  • Article

I have recently worked out a VBScript to list delegate of the Outlook Mailbox using CDO 1.2.1 via VBScript and thought of share it with you all, here is the sample code:

 Dim objSession 

 Dim strProfileInfo 

 Dim strServer 

 Dim strMailbox 

 Dim objFolder

 Dim objMessages

 Dim objMessage

 Dim oFields

 Dim oField1

 Dim oField2

 Dim oFBFolder

  

 'TODO:Change Server and Mailbox info

 strServer="Server"

 strMailbox="User"

  

 strProfileInfo = strServer & vbLf & strMailbox

  

 Set objSession = CreateObject("MAPI.Session")

 objSession.Logon , , False, False, , True, strProfileInfo

  

 writelog( "Mailbox")

         

     writelog( "  ==> ")

     writelog( objSession.CurrentUser)

     writelog( vbCrLf)

 Msgbox "Logged On!!!"

  

 ' Reference the root folder by passing ID of ""

 Set oRoot = objSession.GetFolder("")

  

 'Connect to the Freebusy folder

 Set oFBFolder = oRoot.Folders.Item("Freebusy Data")

     Set objMessages = oFBFolder.Messages

  

     For Each objMessage In objMessages

  

         If objMessage.subject = "LocalFreebusy" Then

             'Get the message fields

  

             Set oFields = objMessage.Fields

             

             On Error Resume Next

  

     For i = 0 to UBound(oFields.Item(&H6844101E).Value(0))

   

                 Set oField1 = oFields.Item(&H6844101E)  ' PR_SCHDINFO_DELEGATE_NAMES

                        writelog "DELEGATE NAMES  ==> " & oField1.Value(0)(i)

                     writelog( vbCrLf)

  

                           Set oField2 = oFields.Item(&H686B1003) ' PR_DELEGATE_FLAGS

               writelog "Delegate can see private  ==> " & oField2.Value(0)(i)

                           writelog( vbCrLf)

        Next

     End iF

 Next

  

 objSession.Logoff

  

 Set objSession =Nothing

  

 Set oField1 = Nothing

 Set oField2 = Nothing

 Set oFBFolder = Nothing

 Set oRoot = Nothing

  

 Msgbox "Done!!!"

  

 Sub WriteLog(ByVal strMessage)

     Dim fs

     Set fs = CreateObject("Scripting.FileSystemObject")

     Dim file

     Dim sScriptPath

     sScriptPath = Left(WScript.ScriptFullName, InstrRev(WScript.ScriptFullName, "\"))

     Set file = fs.opentextfile(sScriptPath & "DelegateListLog.txt", 8, True)

     file.Write strMessage

     file.Close

 End Sub

Please refer to the following MAPI properties used in the above sample to list delegates of the mailbox:

-
PidTagScheduleInfoDelegateNames Canonical Property
https://msdn.microsoft.com/en-us/library/cc839497.aspx

Contains the names of the delegates.  
  
  
Associated properties: PR\_SCHDINFO\_DELEGATE\_NAMES, PR\_SCHDINFO\_DELEGATE\_NAMES\_A, PR\_SCHDINFO\_DELEGATE\_NAMES\_W  
  
  
Identifier: 0x6844

If you interested in exploring further details regarding how delegate settings works in Outlook then refer to:

However, if you just targeting Exchange Server 2007, I would highly recommend you to use EWS(Exchange Web Services)
