All, I recently configured a VPS for my website and email. Once I got things working, I created a MS Outlook account to send/receive email from the server. However, when I did this, I had only a self-signed security certificate on the server and I received the message, "The server you are connected to is using a security certificate that cannot be verified." To work around the problem, I clicked 'View Certificate", then installed it. I now have a proper security certificate on the server and it works properly (confirmed when I set up a MS Outlook account on another machine). Question: How do I locate and remove the certificate (associated with the self-signed certificate)? I imagine that I need to use the Certificate Manager, but I looked through everything listed there and did not find anything that seemed correct. The Outlook Trust Center also did not seem to have anything useful. Thanks.
