outlook 2007 client issues a certificate error on startup

we have a small network based on sbs2011 with exchange, and outlook 2007 clients.

one (only) of our workstations has a problem starting outlook 2007 where a certificate error is issued.

our ssl certificate is installed and working on our server and is fine for all other users.

the error states :-

the security certificate has expired or is not yet valid

the name on the security certificate is invalid or does not match the name of the site

when we view the certificate path it is looking at the totally wrong certificate.

given that all of the other users are ok, how do we correct this windows 10 / outlook 2007 client to use the correct certificate?

any assistance much appreciated.

many thanks
