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. Neil C Fritz
