Mudi2:

I'd like to do the same for my office. Can you give me some pointers on how to do this? Which ports to blocks, restrictions, etc.

Thx.

i solved the problems by reading these articles;

for outlook:

tutorials/Making_Outlook_Express_Work_with_ISA_Server_Quick_Start_Guide.html

for messengers
--------------

http://www.isaserver.org/

tutorials/How_to_Block_Dangerous_Instant_Messengers_Using_ISA_Server.html

p.s for blocking instant messengers, there are two ways .. both are being discussed in the above article. if you install firewall client on each of client system then u can block messengers easily by giving ISA server the .exe file name of each messenger .. but if you don't install firewall client on each of client PC, then you have to block the IP addresses and ports that these messengers use to communicate

let me know if you stil face some problem
thanx

Nice, but a little pricy. How has your experinace been with it?
I have setup some of the users in question with fwclient and added them to the ALL ACCESS, ALL IP group and they connect fine, the issue is finding out when I added them to a group that had ICQ and 5050 ports opened to them, why they couldn't go out. (the im web sites aren't blocked)
What do you think?
