SQL Contacts to Exchange (Outlook)

After being given the task of making one of our application databases be the source of a public folder contact list in Outlook, I came to find that the task is not as easy as it may seem. There are about a billion different ways to do it and you can see some of them here. The one that was decided to be the best for our purposes was Stephen Toub's Outlook Contact Provider. After implementing some caching on the project, it did exactly what we needed and it works great. This basically mimics a SharePoint web service and uses a custom provider to get the contacts from a database. I ran into a little trouble because of the conversion to ASP.NET 2.0 but after those issues were resolved, it worked like a charm.
