I'm trying to change from a self signed cert on the exchange WAF rule to a CA cert, and I'm able to successfully add the CA to the sophos as well as add the cert, but, I do not get it on the drop down list of available certs to select.
What I've done is download the IIS cert from Godaddy, and upload it as a .p7b cert - I've tried googling this and various openssl commands to change cert formats in an attempt to troubleshoot, but I can't seem to figure this out.
If anyone has any insight I'd greatly appreciate some pointers here.....cert warnings for everyone using their email is no fun.
