Showing Error: HTTP/1.1 403 (Forbidden) while creating an appointm

[Atul Saxena]

While creating an appointment, I am getting Error: HTTP/1.1 403 (Forbidden)
error.

My code is:

<?xml version='1.0'?><aropertyupdate xmlns:a='DAV:'

oXMLHttp = CreateObject("Microsoft.XMLHTTP")
oXMLHttp.open ("PROPPATCH",
"http://192.168.111.10/Exchange/[email protected]/Calendar/", False,
Me.UserNameAlias, Me.Password)
' Set up request headers.
oXMLHttp.setRequestHeader("Content-Type", "text/xml")

' Send the query.
oXMLHttp.send(sQuery)

Response is:

<?xml version="1.0"?><a:multistatus
xmlns:b="http://schemas.microsoft.com/exchange/"
xmlns:a="DAV:"><a:response><a:href>http://192.168.111.10/Exchange/[email protected]/Calendar</a:href><aropstat><a:status>HTTP/1.1

This error is not coming when I am updating any appointment but at the time
of creation this response is coming. Please tell me the solution of this.

Thanks in advance.
