Proxy Settings for Outlook in WP 8

[gudnuf4u]

Hi,
I'm trying to convince my friend to get a WP8 and he asks if he can connect to his Outlook work email to sync with his contacts and calendar. I told him yes but his work also has a requirement to connect via proxy settings ...I'm not to familiar with proxy settings on Outlook as I tried to look on my wife's L920 and all I found was Advance settings, Doman Name and User credentials settings...I don't see anything for proxy

anybody familiar with proxy settings to connect to work Outlook? Let me know

thanks
