Hi there,


I'm trying to write a simple program that fetches a users contacts from an Exchange 2003 server, run their number through an address list (i.e. white pages) and saves them again. I managed to fetch the contact info using WebDAV, but when I try to save the info back (using PROPPATCH), I get an 403 error.


I have the following query:
 String url = "https://myserver/exchdav/"; //This is the URL used to fetch the contact info, without problems.

 [...]


 public string updateContact(Contact c)
 {
    String query = ""
    + ""
    + ""
    + ""
    + "urn:content-classes:person"
    + "IPM.Contact"
    + "" + c.address + ""
    + ""
    + ""
    + "";

    //c.href holds the url directly to the contact, i.e. https://myserver/exchdav/myuser/contacts/mycontact.EML
    return this.sendRequest(c.href, query, "PROPPATCH"); ;
 }

   The sendRequest method invokes all the credentials and all seems fine. It even returns an "OK 200" response at first, but when i read the responseStream it says 
 https://myserver/exchdav/myuser/Contacts/mycontact.EML
 HTTP/1.1 403 Forbidden



I do not necessarily need to use WebDAV, if there's an other easier/better/working way of doing this, please let me know.


Any ideas?
Regards
