.Net integrating outlook in Web application

How can I integrating an outlook calendar in开发者_StackOverflow中文版 my web application for managing employees so that I can assign tasks to only those employees not on leave?

Since you're doing this from the server side, you will need to connect to the Exchange Server rather than integrate directly with an Outlook Calendar.

I have not done this myself but using Exchange Web Services it shouldn't cause too much trouble; check out the Exchange Web Services Reference.
