Copying Items (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This content is no longer actively maintained.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 copy items using the World Wide Web Distributed Authoring and Versioning (WebDAV)
- Create a WebDAV COPY Method request. The request Uniform Resource Identifier (URI) for the command is the URI to the item that you want to copy.
- Set the HTTP Destination Header to the URI for the copied item.
- Send the request. The body of the request should be empty.
- 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 Basic® Scripting Edition (VBScript), Microsoft Visual C++®, Microsoft C#, and Visual Basic .NET code examples.
The following example shows a typical COPY Method request:
COPY /pub2/folder1/folder2 HTTP/1.1 Destination: /pub2/folder1/folder3 Host: hostname
JScript
The following example uses an instance of the Microsoft.XMLHTTP Component Object Model (COM) class to send a COPY Method request to an Exchange store.
// Note: It is recommended that all input parameters be validated when they are
// first obtained from the user or user interface.
function copyItem( urisource, urito ) {
// Initialize the XMLHTTP request object.
var Req = new ActiveXObject("Microsoft.XMLHTTP");
// Open the request object with the COPY method and
// specify that it will be sent asynchronously.
Req.open("COPY", urisource, false);
// Set the Destination header to the destination URL.
Req.setRequestHeader("Destination",urito);
// Send the COPY 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;
}
VBScript
The following example uses the COPY Method to copy test.eml from TestFolder1 to TestFolder2.
Option Explicit
' Variables.
dim strSrcURL
dim strDestURL
dim strUserName
dim strPassword
Dim req
strSrcURL = "https://server/public/TestFolder1/test.eml"
strDestURL = "https://server/public/TestFolder2/test.eml"
strUserName = "Domain\Username"
strPassword = "!Password"
' Initialize the XMLHTTP request object.
Set req = CreateObject("Microsoft.xmlhttp")
' Open the request object with the COPY method and
' specify that it will be sent asynchronously.
req.open "COPY", strSrcURL, False, strUserName, strPassword
' Set the Destination header to the destination URL.
req.setRequestHeader "Destination", strDestURL
'Send the COPY method request.
req.send
' An error occurred on the server.
If req.status >= 500 Then
wscript.echo "Status: " & req.status
wscript.echo "Status text: An error occurred on the server."
Else
wscript.echo "Status: " & req.status
wscript.echo "Status text: " & req.statustext
End If

C#
The following example uses the System.Net.HttpWebRequest object to send a COPY Method request to an Exchange store.

using System.Net;

[STAThread]
static void Main(string[] args)

System.Net.WebResponse Response;
System.Net.CredentialCache MyCredentialCache;
string strSourceURI = "https://server/public/TestFolder1/test.txt";
string strDestURI = "https://server/public/TestFolder2/test.txt";
string strUserName = "UserName";
string strPassword = "!Password";
string strDomain = "Domain";
try
{
// Create a new CredentialCache object and fill it with the network
// credentials required to access the server.
MyCredentialCache = new System.Net.CredentialCache();
MyCredentialCache.Add( new System.Uri(strSourceURI),
"NTLM",
new System.Net.NetworkCredential(strUserName, strPassword, strDomain)
);
// Create the HttpWebRequest object.
Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(strSourceURI);
// Add the network credentials to the request.
Request.Credentials = MyCredentialCache;
// Specify the COPY method.
Request.Method = "COPY";
// Specify the destination URI.
Request.Headers.Add("Destination", strDestURI);
// Specify that if a resource already exists at the
// destination URI, it will not be overwritten. The
// server would return a 412 Precondition Failed status code.
Request.Headers.Add("Overwrite", "F");
// Send the COPY method request.
Response = (System.Net.HttpWebResponse)Request.GetResponse();
// Close the HttpWebResponse object.
Response.Close();
Console.WriteLine("Item successfully copied.");
}
catch(Exception ex)
{
// Catch any exceptions. Any error codes from the COPY
