We use dreamweaver for our website development. We wish to have users register and log their downloads of pdf's in an access database (web host won't support mysql).

I then want to extract the user info to create new records in exchange public folder or append to a user a note showing what they downloaded (pdf).

My question is this--
Is it best to write code against outlook (local client) or directly to exchange server?
If I go directly to exchange server, will it work in a hosted environment or does the instance of exchange HAVE to run on a local server?

Thanks!
