If using outlook 2007 then:
At the top of thisOutlookSession but after option ... (if present) place the line, (unless itself already present):
Private WithEvents olkMailItem As Outlook.MailItem
Now paste the snippet for Application_ItemLoad ... if the sub already exists then simply make sure the specific line is therein.
Similarly paste the snippet for olkMailItem_Open ... if the sub already exists then simply make sure the specific line is therein.
