exchange emails within asp.net application

Inside my ASP.NET application, I would like to add an iframe where I can display the emails from our exchange server for the logged in user. The web application uses forms authentication with custom authentication (passwords are hashed and stored in db).

Is there a way to show OWA within my web app without prompting the user for password (OWA uses windows auth开发者_如何学Pythonentication)? Can I use impersonation in some fashion or establish a trust between my IIS server and the server running OWA?

Has anyone tried this before?

If you are using an iframe for that, then it is a separate process in terms of authentication. Requests from the iframe are sent to OWA server just as you had opened the page in full screen.

However, it is possible to configure your Exchange server to allow windows authentication, see here: http://support.microsoft.com/kb/300656

This way you will authenticate with windows forms authentication to your web application and with windows auth to the OWA server.

I think you would have to have the Windows authentication be the authentication source for the website - or at least map accounts in the website to accounts in OWA

DNN does something a little like this with its Active Directory security provider. Might look at the source of that for some ideas - http://dnnauthad.codeplex.com/
