Outlook Web Access email on Mail app

As the name "Outlook Web Access" says, this Exchange Server feature is meant to access a postbox using the web. So you do not need a mail client, but a web browser to use it.

If you wish to connect to the Exchange Server using Mail, you need to enable the SMTP- und IMAP-connector on the Exchange Server. After having done this, you can set up your Exchange account just like any other IMAP-mailaccount.

...which is kind of a bummer since Entourage uses webdav to connect to exchange using webmail, instead of pop or imap...just that mail can't do it, doesn't mean that something else can't...
