Okay I have ready many documents on how to create a self signed certificate and I think my very novice understanding of how this works is getting in the way so I am trying to see if the experts can help be understand.

I want to be able to allow users to connect to the OWA, Activesync and have non-authenticated users have access to our external web site.  

Well if I understand things correctly the best way to handle the exchange is to use 443 (SSL).  Well we dont have a very big IT budget nor do I have the understanding of how ssl is implemented or works so I was hopping someone had away of explaining to me if I could use a self signed or created certificate from my internal CA?

If this is not possible what do you recommened?

    You can create a self signed Cert from the server or an Internal CA.  It will be just as secure as a purchased certification but users who access the https portion of your website (owa) will recieve a security warning.  I would recommened buying a SSL as they are not as expensive as you might think.  Go-Daddy certs are very resonable, work well, are are easy to install.  They walk you through the process and give installation instructions based on what IIS version you are using.

    Firstly you can get a commercial SSL certificate for less than $60 per year and the amount of time it will save is well worth the money.

    If you go for the self-certified certificate then this will work whilst you are still using ISA2006 - if you move up to Forefront TMG things change and you will really be looking at acquiring a store-bought certificate. When using ISA Server, the certificate needs to be installed twice - once on the server that requested it and secondly on the ISA server so that it can be included within the web listener that you create as part of the ISA publishing rules.

    If you are allowing external users to access your site, again you should go for the certificate issued by a recognised authority. there is nothing more disconcerting then seeing a message that you are advised NOT to visit this site becuase it is deemed as insecure. If someone Googles the error message then they will be advised that this could be a spoof site or that they may be being hi-jacked and redirected to a malicious site - not good for your business.
