    Lync features yes but the users will be prompted to trust the existing certificate since their domain isn't included in the certificate. For Exchange EWS to work you need to set up autodiscover.

    You only need to add to the edge certificate the sip domains not all the smtp domains.

    Hi,

    In the "old OCS days" you need to have the same, now you can have smtp different from sip domain. You will need to configure all autodiscover URLs for all smtp domains.

    In Lync you can point _sip._tls.<sip domain> to sip.<sip domain> and install the certificate including sip.<new sip domain>, this will prevent popup in Lync Client asking to trust the certificate. Check the following URL is for OCS 2007 R2 but the dns record concept also applies to Lync:

    The dns Srv record method will work without having to purchase new certificates. What I want to know is will all the lync feature work for the remote clients using dns Srv record method?

    That's just it, I won't to avoid changing my current certificate. I was under the assumption that I wouldn't have to when using the DNS Srv method?

    That isn't related to the difference between SIP and SMTP domains. Is related to the additional sip domains, all your users in those domains will be prompted to trust Front End/Edge certificate. Is highly recommended to add the sip.<new sip domain> to the cert in the EDGE external interface.
