We have a channel in development that pulls down calendar information from Exchange via WebDav. To do this, we created a user Id that has administrator permissions to all mailboxes (we have not found a way to restrict this to calendar information only). Using this ID, we connect to the Exchange servers via the Slide WebDav client and execute a select against the calendar for the current user. The only problem I have run into is timeouts on the Exchange server. From what I can tell, the query is sent without any problem, the connection blocks until the query completes (which can take several seconds), which causes the channel to timeout. We're hoping that we'll have better reliability from WebDav when we move to Exchange 2003, until then, getting the calendar information successfully is hit or miss (I'd say about 60-75% of the time it succeeds).
Microsoft has some articles that explain how to make the query via
WebDav:

Hope this gives you some ideas. Once I get a chance to clean the code up a bit, I'd be happy to share it.

One way to work with OWA is using Simulated Single Signon to login using Form Based Authentication. Note that Form Based Authentication is greyed out on a cluster server because FBA isn't available on a cluster.
