You can try installing the certificate by itself. &nbsp;Just open the file, and select &quot;Install...&quot;, then instead of automatically selecting the location, Browse the stores, check the box for &quot;Show Physical Stores&quot;, and under Trusted Root Certificate Authorities, put the cert in Local Computer. &nbsp;Then try browsing the site through OWA, and see if you get a certificate error. &nbsp;<br />
