building web application like outlook web access [closed]

[metallicr]

I'm trying to develop a web application like outlook Web Access with advanced functionality.my basic goal is to migrate mails from exchange server to my custom Mail app.Now I'm using EWS managed api to connect to exchange server (2010) and works fine but it doesn't give full functionality (e.g. I can't get account information like user name and language, I can't get Folders icons... etc )I'm using C# asp.net with visual studio 2012, and dotnetnuke framework.any suggested ideas?Thank you in advance
