Ok finally I have solved this issue .

Let me tell you how you can do so .

Two thing you need for this is.

1) Your exchange server url

You can get that by this approach . For exchange server url , credit goes to this URL .

https://support.neuxpower.com/hc/en-us/articles/202482832-Determining-the-Exchange-Web-Services-EWS-URL

I am adding step also

2. Use Microsoft Outlook (2007 and later) that connects to the same Exchange EWS Connector.

Hold the Ctrl key and right click on the Outlook Icon in the system tray
Select “Test E-mail Auto Configuration” from the menu
Type in an email address located on the desired Exchange server
Click Test
The URL is listed as 'Availability Service URL'

After you have url do this .

2) Send POST text\xml request

url https://--your-exchange-url--/EWS/Exchange.asmx

and the xml body from here
