Hello Everyone,

I just started in a new place and one of the issues I am facing is that on all computers, when I go to a website, it says that there is a certificate error. This is the output:

The security certificate presented by this website was not issued by a trusted certificate authority.

Firefox: uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)

It's something that I haven't seen before so I don't even know where to start. According to the techs here, it started almost right after they upgraded Exchange.

Has anyone seen this before?
