<p class="MsoNormal">Hi all, <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In regards to the question of Microsoft requirements for OCSP URLs in S/MIME certificates, I had to do quite a bit of digging around the various teams across Microsoft. However, I can confirm that OCSP can be optional for any non-TLS certificate
types. This includes S/MIME. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">OCSP is not optional for TLS at this time. Thus, we will be changing our policy to : “All non-TLS end-entity certificates must contain an AIA extension with a valid OCSP URL”. We will continue to investigate OCSP for TLS.
