Hi
As it seem .. and even if he dont have Firewall Client installed, he should install it
I have Such a problem where client in my network have a problem can not connect to a POP3 Server using MS Outlook
I had Create a Rule that allow POP3 and also a Rule to Allow ALLOUTBOUND TRAFFIC From Internal To External To All Users, But as it seem that ISA Server is configured to Block the Connection for Outlook what ever the Portocol that is being sent to the external as its in ISA Server (( OutLook disable   1))
Anyway
As Qaisar Naseem says ((Even I created a firewall rule to allow all outbound traffic to external, but unable to solve the problem)), so it seem that enabling so will help
Anyway .. do you have a Better method for enabling this and Allowing the outlook to connect to the external without having to change it from ISA
Thanks alot

A couple of things:
One, you don't know that he is running a firewall client.  Secondly it is never recommended to just enable full access to an overall application when you can more finely restrict access based on protocol.   The client may simply be using POP3 -- it would be silly to just "allow Outlook" as an application to all of your firewall clients when you can just allow POP3 (or whatever it is) to only the clients that need it.

HI
This is normal for ISA and you can fix this by going to:
 
Open the ISA Server Console and expand the Configuration, and select General, and then Click on "Define Firewall Client Settings", You will have a new Window for the "Firewall Client Settings"
Click on the Application Tab and from the list select Outlook
You will notice that its like this:
Outlook  Disable  1
change the value to be
Outlook  Disable  0
and on the Firewall client on the user PC  make sure that you click on Detect Now Or simply restart your Computer
This work for me perfect
Have a nice time
 
 
Note that if the value is not present .. then  simply create it

What protocols are you using to connect to the server?  I'm assuming you are talking about an internal Outlook client connecting to an external server.  What kind of ISA client is the host?  Are you using SNAT or FWC?   A little infoz, please.

Hi,

 

I am using Windows server 2003 network with ISA 2004 as proxy. I am having problem in passing MS outlook requests. Even I created a firewall rule to allow all outbound traffic to external, but unable to solve the problem. Outlook configuration is quite OK as when I by pass proxy, it works fine.
