For just the Inbox or all folders of a mailbox?
Can't you just grap the MAPIFolder object you're querying and grab the UnReadItemCount value?

hi neo,

just for ONE mailbox (exchange server)
The following will work if you want to use the Outlook Object Model and VB. (Information was taken from )

Option Explicit

   Private Sub Main()
      Dim olMAPI As Outlook.NameSpace
      Dim Folder As Outlook.MAPIFolder
      Const FOLDER_TO_OPEN = "Mailbox - John Doe"   'Modify as appropriate

      Set olMAPI = GetObject("", "Outlook.Application") _
      Call PrintFolderNames(olMAPI.Folders(FOLDER_TO_OPEN), "->")
      Set olMAPI = Nothing
   End Sub

   Sub PrintFolderNames(tempfolder As Outlook.MAPIFolder, a$)
      Dim i As Integer
      If tempfolder.Folders.Count Then
         Debug.Print a$ & " " & tempfolder.Name & "  ";
         Debug.Print tempfolder.UnReadItemCount
         For i = 1 To tempfolder.Folders.Count
           Call PrintFolderNames(tempfolder.Folders(i), a$ & "->")
         Next i
         Debug.Print a$ & " " & tempfolder.Name & "  ";
         Debug.Print tempfolder.UnReadItemCount
      End If
   End Sub
