Exchange 2007/Outlook 2007 - OWA and Outlook Anywhere are configured and using a commercial SAN cert.
Issue - When a user opens Outlook remotely it takes between 30 - 90 seconds before the log in box comes up and prompts for username and password. In Account Settings - Micsosoft Exchange proxy Settings - I only have "On slow networks, connect using HTTP first, then connect using TCP/IP" checked -However when I also check "On fast networks, connect using HTTP first, then connect using TCP/IP" - the log in box pops up as soon as you open Outlook outside the network - which is my goal.
Bad News - Then when your back on the network you always get prompted for username & password.
I was thinking of trying to set up a GPO or a site policy that disables "On fast network...." when connect to the corporate LAN - but I am not sure how to accomplish this or if this is the best solution to my issue.
