We have a departmental public folders and a sink script that informs
all the users in that department when there is a new message in the
public folder.  The script that is triggered when a new mail
notification come through looks like this:

Sub ExStoreEvents_OnSave(pEventInfo, bstrURLItem, lFlags)
    Dim aBRL, aUser
    Dim i
    Dim oShell
    Dim sMBox, sMessage

    Call LogEvent("ExStoreEvents_OnSave","Begin")

    ' a new item has been saved in a public folder, so send out an alert
to all
    ' administrators and ISCs at this location

    ' parse the url to find out what mailbox/folder caused the event
    aBRL = Split(bstrURLItem,"/")
    sMBox = aURL(UBound(aURL)-1)
    Call LogEvent("ExStoreEvents_OnSave","PFolder=" & sMBox)
    Call LogEvent("ExStoreEvents_OnSave","Message=" & aURL(UBound(aURL)))

    ' grab the array of users
    aUser = RetrieveUsersForMBox(sMBox)

    ' create a command shell to send the net send
    Set oShell = CreateObject("WScript.Shell")

    If IsArray(aUser) Then
        ' an array of users was passed back, so net send them that they have
mail
        sMessage = Replace(S_MAIL_ALERT,"<MBox>",sMBox)
        sMessage = Replace(sMessage,"<vbCR>",vbCR)
        For i = 0 To UBound(aUser)
            'WScript.Echo("net send " & aUser(i) & ": " & sMessage)
            Call oShell.Run("net send " & aUser(i) & " " & sMessage)
            Call LogEvent("ExStoreEvents_OnSave","Notify=" & aUser(i))
        Next
    Else
        ' no user is set up for this location, so net send to the sys admin
        sMessage = Replace(S_MAIL_NO_ADMIN,"<MBox>",sMBox)
        sMessage = Replace(sMessage,"<vbCR>",vbCR)
        Call oShell.Run("net send " & S_ADMIN_ALERT_USER & " " & sMessage)
        Call LogEvent("ExStoreEvents_OnSave","NoUsers:Notify=" &
S_ADMIN_ALERT_USER)
    End If

    Set oShell = Nothing
    Call LogEvent("ExStoreEvents_OnSave","End")
    Call LogEvent("","")

End Sub

the time without any new email message in the public folder.  Its
