At some point in the recent past, enveloper quit working with my Outlook address book.
The enveloper option drops down from the "tools" menu, I highlight an address, the enveloper screen comes up with the screen on it, I click "print" and I get an error message:
Run time error "5'
Invalid procedure call or argument

This only happens once. Next time I try it's blank.

How do I fix enveloper so I can use the Outlook address book?
