Outlook 2007 Won't Open and I Can't Find the Server

Outlook and Exchange are interrelated.

The Outlook 2007 email program works with the Microsoft Exchange server to transfer data. Usually, Outlook connects to Exchange automatically, but errors can occur between the two programs. You may receive an error message when you try to open Outlook 2007 or Exchange. You might see a window that says "The action cannot be completed," "Your Microsoft Exchange Server is unavailable" or "Cannot start Office Outlook 2007." The solution is to get the two programs to connect to each other again.
