401 Unauthorized - WebDav to Exchange

401 Unauthorized - WebDav to Exchange

Post by struve » Sat, 21 Jan 2006 06:12:57


I am trying to make a call to the exchange server via web dav and
always get a 401 unauthorized error. I have read all the posting about
this and tried the things mentioned to no avail. I checked the server
running owa and it appears to be set up correctly. I'm making this
call from my c# app. If I navigate directly to the url I'm using in
webdav it works fine. It only returns the 401 error when I try to
access it in my .net app. Any ideas on how to fix this?

Thanks.

2. Biztalk Http Receive 401 Unauthorized Error

Hello,

I am using BizTalk 2004 SP1 on a windows 2003 Server machine. I am
trying to work on a sample that uses Http Receive to receive an XML
into a Receive location. I have developed a sample web application that
sends an XML using BTSHTTPReceive.dll. When I try to post the XML, I
get the following error -

Unable to complete web request. Web Exception error: The remote server
returned an error: (401) Unauthorized.

This is for a sample from chapter 6 of the Biztalk Server 2004
Unleashed book.

Any ideas what I am doing wrong?

Thanks for the help
Ashok
