Exchange Authentication dll:

https://red002.mail.emea.microsoftonline.com/owa/auth/owaauth.dll

sending style is:

request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";

And sending following message

destination=https://red002.mail.emea.microsoftonline.com/owa/[email protected]/?ae=Folder&t=IPF.Appointment&[email protected]&password=xxxx

I'm getting this error:

The remote server returned an error: (400) Bad Request.

If I use the path in a webbrowser it is accesable. It is not a bad request indeed. The server is Exchange server 2007 and replaced the path for owa. But it can not auth the path?

.NET WebRequest.PreAuthenticate not quite what it sounds like

as seen on West-Wind - Search for 'West-Wind'
I’ve run into the problem a few times now: How to pre-authenticate .NET WebRequest calls doing an HTTP call to the server – essentially send authentication credentials on the very first request instead of waiting for a server challenge first? At first glance this sound like it should be easy:… >>> More

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
