You will need a SSL Certificate to setup OWA over HTTPS.
However you don't need neccessarily buy a certificate.
You can use Microsoft's SelfCert utility or if you've got access to your Certificate Server on your domain then you can sign your own certificates. Just do the certificate request and exported it to a file.
Then access your Certificate Server via a browser and sign it yourself.

For the rest of the setup, look at the tutorial above.
Please note: You will still need to publish OWA via firewall like ISA or Forefront to make it safe on the WWW.

When you say "publish", I am assuming you just mean to open a port?

Also, when it comes to any use of things like RWW or OWA over HTTPS using a self-signed certificate, I am assuming that this is safe through encryption - right?

Also, if I am comparing a third-party cert to a self-signed, then the only advantage that a third-party cert has is that it does not need to be distributed before use? I would of thought that if my Server has Certificate Services installed, then it could distribute over the Internet?
