How do I set up an account for an Exchange server?

I have set up my personal email account using eM. It is an IMAP account, no problems. But I want to set up an account for my work email, which is also IMAP, but is based on an exchange server. I have previously setup accounts to access this email system without problems on my iPhone and on Apple mail. This machine is a PC running Windows 7.

The info I put into my iPhone to set up the account was minimal. Setting up the Apple Mail account resulted in a bit more info, but I think that the two systems talked to each other or something - there is a path shown for when connecting to the Exchange server.

With what I have done, eM makes the connection with the Exchange server, but times out. There must be a special way to configure the data to make it work?

Any help appreciated!

what error message does it display?
