Problem 1 solution
since it is a self-signed certificate it will have to be imported into each computers trusted root providers.
Problem 2: the subject name is an ip addess which unless the outlook users are accessing the site VIA the ip address you will get an error. as the name 192.x.x.x doesn't match the servers fully qualified domain name

it has nothing to do with the sonicwall

Hi David,

Im not an expert,

My outlook anywhere cert is purchased from godaddy, is not a self signed cert. As for the IP, i dont think users will access the page through IP as he is not a computer expert as well.

i wanted to know why this cert will prompt out? Sorry, your english migh be too deep for me. Might need you to explain in a simple english.. Thanks
