Copying Items (WebDAV)

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;

}

The following example uses the COPY Method to copy test.eml from TestFolder1 to TestFolder2.

Option Explicit

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
