This is the moment the search for a "serial key" happens. The pressure is on. The IT budget for the quarter is spent, or the procurement process takes weeks. You just need the job done now.

You head to Google, typing in "mapilab duplicate email remover serial key" or "crack".

Here is where the story takes a turn. This search often leads to two destinations, neither of which ends well:

Tech-savvy users can run a simple VBA script inside Outlook to remove duplicates. Here’s a basic example (always back up your PST first):

Sub RemoveDuplicateEmails()
    Dim olFolder As MAPIFolder
    Dim items As Items
    Dim dict As Object
    Dim item As Object
    Set dict = CreateObject("Scripting.Dictionary")
    Set olFolder = Application.ActiveExplorer.CurrentFolder
    Set items = olFolder.items
    For i = items.Count To 1 Step -1
        Set item = items(i)
        If item.Class = olMail Then
            key = item.Subject & item.SentOn & item.SenderEmailAddress
            If dict.exists(key) Then
                item.Delete
            Else
                dict.Add key, Nothing
            End If
        End If
    Next
End Sub

This method requires no serial key but demands caution.

Cracked versions may be modified to disable certain functions. You might think duplicates are removed, but corrupted logic could delete unique emails or leave duplicates intact.
