Outlook - attachment warnings and folder cleanups

'This second one is trickier but more useful. It converts all mails in a folder to plain text and removes attachments. You have to add a rule to use it
'Enter this one in "ThisOutlookSession" too but add a rule to run when mails arrive and set it to run this script
'DO NOT enable the rule. Run the rule on a need-to basis on your saved emails. You can even opt for subfolders to processed.
'This should drastically reduce your PST file size. You may need to force a "compact now" on your PST file to see the size difference.
'Also, for mails with embedded images you may need to run this more than once since it'll first convert the images to included files (inaccessible from the UI)
