Got that syncing feeling? Cloud's client-side email problem
https://www.theregister.co.uk/2017/08/04/cloud_syncing_feeling/
Despite predictions of its demise, we've been happily using email in business since it first became widespread more than two decades ago. In many ways it's defined the way we compose, reply or send digital messages. A number of technologies have consolidated and extended it to something that became called "collaboration".
Windows for Workgroups or Novell Netware server brought file share. We've been creating, saving and attaching files pretty much the same way ever since. VPN work remotely as if at our desk – albeit a hell of a lot slower, unless we had Citrix or Terminal Services remote desktops.
