I'm coming across a weird issue when I try to use WebDAV from my .net web
application to open a users Contacts folder in Exchange.
Depending on how I set up the authType in the NetworkCredential I use to
access the Exchange store, I get different results.
The account myDomain\SCM is an enterprise administrator

The request fails when I use Basic as an authType and the virtual directory
has both Anonymous and Integrated security on it

Cmd=contents 80 - 172.31.1.18 - 401 2 2148074254
authType: Basic
Credentials: myDomain\SCM
ExchWeb virtual directory security: Anonymous, and Integrated Windows
authentication

I don't understand this one, the request seems to fail, then it works

Any idea?

Sounds like there is a disconnect between the "client" auth and the server.
Do you pass the credentials beforehand? .NET will sometimes hit the server,
get unauthorized and then pass the credentials which is perhaps what you're
seeing in #1.

Tom,
Since it works fine when you browse directly using IE, I think you're right
about the credentials.

I have a call in to Microsoft Support to try and figure out why Basic works,
but NTLM doesn't.

Thanks!

Fixed, the issue.

Added Integrate Authentication as a permission on the Exchange virtual
directory
