As a tech professional, Windows 10 is probably the worst OS for a professional environment. With the privacy concerns, self promotion, the force fed apps (especially for gaming… yes Pro version), and the fact that whenever a user logs into a workstation forcing the apps to AUTOMATICALLY download (sucking up bandwidth and making the machine unuseable for 10 minutes). Microsoft has dropped the ball here and most tech users agree. My point of posting this here is because of the native Mail debacle. This is important for professional users, as well as the average user. Of course Microsoft said the work around is to have the user use their iOS app, quite frankly I think it's terrible. https://www.macrumors.com/2017/09/20/apple-microsoft-email-server-issue-mail-app-ios-11/amp/ I would like to believe Apple tried to fix this issue, but Microsoft is with holding information in order to force users of their mail to use the iOS app. I use Outlook for my personal email (over a decade) and Office 365 for business and I can tell you that it evolved into an uncontrollable mess. It's literally nothing but pointless add-ins and a far reach from professional (not to mention slow to load on any browser including Edge). Sorry, just had to vent!
