All in all if someone is looking for an alternative for Microsoft Outlook that doesn't have all of the extra bells and whistles, but is still usable, I would highly recommend Mailbird. It is a great email client that has a lot of compatibility and the user interface keeps things simple and pleasing on the eyes. It doesn't have a ton of features, but it makes up for that by having some extra plug-ins to put useful services directly into the client. For example, I have my Google Calendar implemented with my Gmail account in Mailbird to be able to see all of my upcoming appointments from within the app. As a Project Fi subscriber, I am also able to access Hangouts from within the app which lets me make calls and texts directly from Mailbird.
