HI guys,
I'm trying to set up outlook for a client on their mac.
the version of outlook is 2011 for mac. it is with an exchange server. I am setting this up on an internal network. (using a VPN with VPN Tracker 6)
I have internet connectivity though the VPN and can Ping the mail server's URL.

However,
whenever I try to send/receive with outlook, I get error -17199

what am i missing?
