Could you define "encrypted"?
Have you tried right-clicking the files in Outlook, saving them to your desktop and opening there?
What exactly happens when you try and open one?
ENCRYPTED - It looks like a bunch of garbage - characters, symbols, numbers all run together. I have opened up a *.pdf file and the right clicking does not respond.
Have you affirmed that Reader is opening the file?
It sounds like it's being opened by Word (or some other application).
If that is the case, you need to associate PDF's with Reader. In XP you can right-click on a PDF, choose "Open with>Choose Program, select Adobe Reader and click the box that says "Always use selected program to open this type of file.
Thanks for your suggestion. The "right click" worked. I can open a *.pdf file now.
Glad that worked out for you.
