Go -> Connect to Server and put in cifs://aaa.bbb.ccc.ddd - it's the same as smb
Setting up Entourage 2008 with an Exchange server:
When Entourage first opens up, it asks you what kind of server you are on. Cancel out of that. You are not able to get through that without entering a valid LDAP server that you can log on to.
Instead, go to Tools -> Accounts and create a new Exchange account.
Account ID, domain, and password are self explanatory and the only other field that is required is the Exchange server field, where you can use the URL for webmail (including the HTTPS and the /exchange at the end).
