Kindly guide me for the same.Thank You in advance.
Error to the Solution Deepu provided.

The Error above was because the form was on my system. I published it on a sharepoint site and it works fine there, but i want a custom form in Outlook to be published on Exchange server (Outlook clients accessing the Exchange server using MAPI or RPC/HTTPS). How do i go about it?
I created a custom form using http://www.techrepublic.com/blog/10things/10-easy-steps-to-customizing-an-outlook-2010-form/2635 and when i mail the form to the recipient, the template used in the begining (e.g Meeting) is sent to the recepient and the Custom form created has to be viewed seperately(which makes no sense). Well, I know this is totally confusing. In short the thing is Custom forms in Outlook i am not able to Publish in Exchange server and also i want to know proper way to create a custom outlook form.
My actual requirement is a a user should use the custom form for Leave Request.
