Hi, I was looking for a macro code which would save attachments and save them with the email subject to a specific folder on my network. I have found this by Graham Major which is excellent and ideal for what I need.
Is it possible that it can be amended to check if the file name already exists and overwrite it with the latest email attachment?

Many Thanks

Sub Test()Dim olMsg As MailItem
    On Error Resume Next
    Set olMsg = ActiveExplorer.Selection.Item(1)
    Save_As_Subject olMsg
lbl_Exit:
    Exit Sub
End Sub


Sub Save_As_Subject(olItem As MailItem)

    For Each olAttach In olItem.Attachments
