After saw that let’s Encrypt work flawless with our webs (all on linux) i want to start using it for our mail server, in this case Exchange 2013 over windows 2012 R2.
Is a standalone server since we a small (30 users) company, we have both front and back end on the same server, as well as all services. Right now we are using self certificate from our Domain CA and you know what issues that brings, not trusted by externals.
There is any guide to setup up this for OWA/Activesync and local outlook clients on a standalone exchange?
Thanks in advance
