I am using Office 2003 on Windows XP.

I have an Excel form file, that contains macros, uploaded into Public
Folders in Outlook. In 2003, the user is given the opportunity to Save the
file locally or Open it directly.

Perhaps in an "On Open", I need a way to programmatically determine whether
the file has been saved by the user - and then disable the macros (I can do
this part already). i.e. I want the user to only Open the file directly from
the Outlook folder, not save it and then open the saved copy.

How can I programmatically identify if the file has been saved somewhere
else vs. opened directly?

Thanks much for your assistance.
