Just to tell you, thru the Microsoft Forum I was told to change the objItem as mailitem to ReportItem and it works so here is the full code that works perfectly....and thanks for your time as usual!!!
Sub MoveSelectedMessagesToFolderUndeliveredEmails()
Dim objFolder As outlook.MAPIFolder, objInbox As outlook.MAPIFolder
Dim objNS As outlook.NameSpace, objItem As outlook.ReportItem
Dim olReport
Dim olMail
Set objNS = Application.GetNamespace("MAPI")
Set objInbox = objNS.GetDefaultFolder(olFolderInbox)
On Error Resume Next
Set objFolder = objInbox.Folders("Undelivered E-Mails")
'Assume this is a mail folder
If objFolder Is Nothing Then
MsgBox "This folder doesn’t exist!", vbOKOnly + vbExclamation, "INVALID FOLDER"
End If
If Application.ActiveExplorer.Selection.Count = 0 Then
'Require that this procedure be called only when a message is selected
Exit Sub
End If
For Each objItem In Application.ActiveExplorer.Selection
objItem.Move objFolder
Next
Set objItem = Nothing
Set objFolder = Nothing
Set objInbox = Nothing
Set objNS = Nothing
End Sub
