we have a small network based on sbs2011 with exchange, and outlook 2007 clients.<br />
<br />
one (only) of our workstations has a problem starting outlook 2007 where a certificate error is issued.<br />
<br />
our ssl certificate is installed and working on our server and is fine for all other users.<br />
<br />
the error states :-<br />
<br />
the security certificate has expired or is not yet valid<br />
<br />
the name on the security certificate is invalid or does not match the name of the site<br />
<br />
when we view the certificate path it is looking at the totally wrong certificate.<br />
<br />
given that all of the other users are ok, how do we correct this windows 10 / outlook 2007 client to use the correct certificate?<br />
<br />
any assistance much appreciated.<br />
<br />
many thanks
