Entourage 'Unknown Error (170)'
If you're like me and spend a lot of time roadwarrioring outside your corporate Exchange network, as well as spend as much time as possible working on non-MS machines, you might find this cropping up in your Entourage one day when you try to get mail. I don't know what, precisely, 'Unknown Error (170)' means or why MS thinks that's helpful, but I can tell you this: in my case, it meant my domain password had expired, and I hadn't been online on a Windows box (or other piece of software capable of handling the password change) recently enough to get the expiration warning.
Logging in to my corporate VPN using Parallels provided me with a password change dialog, and once that new password was entered into Entourage it became all happy again. I had to quit/restart it after entering the p/w in order to force it to refresh the mailboxes properly, but it did so fine after the restart.
