Our SAN certificate for Exchange will expire middle of next month. Since it has been 3 years since I did a Exchange certificate I have questions. As we have both versions of Exchange in house and Office 365 Hybrid can I use just one certificate for both Exchange versions. Do I create a certificate CSR from Exchange 2013 or Exchange 2010 or both. What are the current best partices for what goes in a SAN for Exchange. Namely to I add server names or just Webmail and Autodiscover. Thanks in advance.
