Dear Sir, I have one pear to pear network (workgroup) with isa 2004 server. My mail server is hosted by third party firm. Now I am able to access my mails through web access. I want to access my mails behind my isa 2004 server with outlook express but it's seem that isa is blocking my outlook express communication. So please help me how to configure my isa 2004 server to be able to access my mails through outlook express client. Warm Regards Mahendra Patil
