This was suggested to me and it looks like a reasonable tool, though i haven't tried it myself. Basically it's a wrapper around OpenPGP which is designed to be easier to use and integrate better with MS Outlook. I don't use Outlook so i'm not sure it's right for me, but might be a reasonable solution for some. Comes in free and pay versions.
