Creating Folders (WebDAV)

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.To create a folder or collection using the World Wide Web Distributed Authoring and Versioning (WebDAV) protocol

Create a WebDAV MKCOL Method request. The request Uniform Resource Identifier (URI) for the method is the URI to the collection that you are creating.
Optionally, set properties for the new folder by sending an XML body in the request. You can set these properties in this request using the MKCOL Method or you can set these properties in a separate PROPPATCH Method after the folder is created. You format the XML the same way as when sending a PROPPATCH Method. For example:
```
<d:propertyupdate xmlns:d="DAV:">
<d:set>
<d:prop>
<d:displayname>Folder 1</d:displayname>
</d:prop>
</d:set>
</d:propertyupdate>
```
When sending a request body with the MKCOL Method, set the Content-Type header to "text/xml" and set the Content-Length header to the appropriate value.
Send the request.
If successful, the response status will be "201 Created".

See Constructing Exchange Store HTTP URLs and Authentication and Security Using WebDAV for more information.

This topic contains Microsoft® JScript®, Microsoft Visual C++®, Microsoft C#, and Microsoft Visual Basic® .NET code examples.

The following example shows a typical MKCOL Method request:

MKCOL /pub2/folder1/folder2/ HTTP/1.1
Host: hostname
Content-Type: text/xml
Content-Length: XXX

<?xml version="1.0"?>
<g:propertyupdate xmlns:g="DAV:" >
    <g:set>
        <g:prop>
            <g:displayname>value</g:displayname>
        </g:prop>
        <g:prop>
            <f:myprop xmlns:f="urn:schemas-mydomain-tld:">Test</f:myprop>
        </g:prop>
    </g:set>
</g:propertyupdate>

JScript

The following example uses an instance of the Microsoft.XMLHTTP Component Object Model (COM) class to send a MKCOL Method request to an Exchange store server.

// Note: It is recommended that all input parameters be validated when they are
// first obtained from the user or user interface.
function createFolder( urisource, vXML ) {

 // Initialize the XMLHTTP request object.
 var Req = new ActiveXObject("Microsoft.XMLHTTP");

 // Open the request object with the MKCOL method and
 // specify that it will be sent asynchronously.
 Req.open("MKCOL", urisource, false);

 if(vXML != "")
 {
  // Set the Content-Type header to "text/xml".
  Req.setRequestHeader("Content-Type","text/xml");

  // Send the MKCOL method request with the specified
  // XML body.
  Req.send(vXML);
 }
 else
 {
  // Send the MKCOL method request.
  Req.send();
 }

 // An error occurred on the server.
 if(Req.status >= 500)
 {
   this.document.writeln("Status: " + Req.status);
   this.document.writeln("Status text: An error occurred on the server.");
 }

 else
 {
   this.document.writeln("Status: " + Req.status);
   this.document.writeln("Status text: " + Req.statustext);
 }

 return Req;

}

C++

The following example uses the MKCOL Method to create a collection in the Exchange store of type "IPF.Appointment".

#include <stdio.h>
#include <iostream.h>

// If necessary, change the file path to match the location of the msxml.dll file.
#import "c:\windows\system32\msxml.dll"

// To use MSXML 4.0, import msxml4.dll instead of msxml.dll.
// #import "c:\windows\system32\msxml4.dll"
// using namespace MSXML2;

int main(int argc, char* argv[])

   _variant_t vPassword = L"!Password";
   _variant_t vAsync = (bool)FALSE;
   bstr_t sReq ="";
   long lStatus = 0;
   BSTR bstrResp;
   BSTR bstrResponseText;
   HRESULT hr;

   // Initialize the XMLHTTPRequest object pointer.
   hr = ::CoCreateInstance(__uuidof(XMLHTTPRequest),

                          (LPVOID*)&pXMLHttpReq);

   // If you are using MSXML 4.0, use the following to initialize pXMLHttpReq:

   // Check the status of pointer creation.
   if (S_OK != hr)

      cout<< "XMLHttpRequest pointer creation failed." << endl;
      return 1;
   }

   try

      // Create the XML request body and set the folder class to "IPF.Appointment".
      sReq =  "<?xml version='1.0'?>";
      sReq = sReq +

The following example uses the System.Net.HttpWebRequest object to send a MKCOL Method request to an Exchange store server.

         System.Net.CredentialCache MyCredentialCache;
         string strFolderURI = "https://server/public/testfolder/";
         string strUserName = "UserName";
         string strPassword = "!Password";

            Request.Method = "MKCOL";

            // Send the MKCOL method request, get the
            // method response from the server.
            Response = (System.Net.HttpWebResponse)Request.GetResponse();

            // Close the HttpWebResponse object.
            Response.Close();

            Console.WriteLine("Folder created at " + strFolderURI + ".");

         }
         catch(Exception ex)

            // method request on the server will be caught here, also.
            Console.WriteLine(ex.Message);

         }
