Nathan Y said: "The past few major releases seem to have been tinkering around the edges rather than fixing the things that matter. Other than making things like ActiveSync and EWS work well perhaps features that would allow for scalability and availability. Let's have the capability to separate IMAP/POP/SMTP and Webmail into separate servers and multiple of each."
Add Calendars to this "scheme" and I'm in full agreement. Indeed, perhaps all ancillary features should be separate services that can be added as needed.
But ST has doubled-down on pushing v16, while many suffering email admins continue to scratch their heads, and users continue to howl.
