Public WithEvents objExplorer As Outlook.Explorer
Public WithEvents objMail As Outlook.MailItem

Private Sub Application_Startup()
    Set objExplorer = Outlook.Application.ActiveExplorer
End Sub

Private Sub objExplorer_SelectionChange()
    On Error Resume Next
    If objExplorer.Selection.Item(1).Class = olMail Then
       Set objMail = objExplorer.Selection.Item(1)
    End If
End Sub

Private Sub objMail_PropertyChange(ByVal Name As String)
    Dim objConversation As Outlook.Conversation
    Dim objStore As Outlook.Store

    If Name = "Categories" Then
       strCategories = objMail.Categories
 
       Set objStore = objMail.parent.Store
 
       If objStore.IsConversationEnabled Then
          'Get the conversation
          Set objConversation = objMail.GetConversation
 
          If Not (objConversation Is Nothing) Then
             'Assign the same color categories to the mails in this conversation
