Hi Abhay,

This is the forum to discuss questions and feedback for Microsoft Office client. There is not so much about Office 365 deployment/server aspects here, I would suggest you to post in the dedicated forum of Office 365 Community, where you can get more experienced responses:

http://community.office365.com/en-us/f/default.aspx

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
