Proxy settings for MS Outlook?

I have managed to set up a LAN network and have internet for both PCs through a Proxy using proxy+ (give me a break - first timer :p). I cant make MS Outlook to work though, no matter what i do.

All other apps that have to use the net have some proxy seting option somewhere so that i can give them the host and the port, but not with Outlook. Any ideas?

claims to work for OE, maybe it works for outlook as well?
