Exchange Server Integration

Hi, everyone:

My company recently adopted the WordPress platform for our intranet; this is the in-house CMS. So far, so good. One question: would there be any way to link with our Exchange 2007 server and create a page where a user can type in a name to access that individual’s e-mail, phone extension, etc? If I am sitting in front of my computer and need to quickly dial Coworker X, I want to merely open our intranet and type in his/her name to see the number. Is there any way to accomplish this using WordPress?

Thank you very much!
