SAN Certificates for Exchange/Office 365 Labs


Can anybody give me clear stesp on how I would generate the SAN certs for my Exchange servuers? They’re running on Azure VMs, so I can get static IPs if they are necessary.

Not sure what to use to request them, where I should request them from, and where to find them if I was successful.
