three key 8.1 app features missing from 10 email app

* Select all . I think I know why this happened (converging the desktop and mobile interfaces, and reflecting the bias against select all in mobile email apps) -- but it still dramatically impairs app functionality. Mystifying that MS would not recognize this as a permitted variance between desktop and mobile, given that it forces people who have to manage large amounts of email (i.e., everyone) back to browser interfaces.

* Ability to switch the replying account / email address of an email to that of a different account from the one to which sent. This is a powerful feature of Outlook and was a welcome addition to 8.1 mail app; no idea why it went away. (Very useful for shifting conversation threads that are non-business to personal account, and vice versa).

* One step switch between accounts

The important ability to set up folders for in-coming emais. We get many emails daily that we need to keep.

Agree 100% with all of the above and I'll add the most important for me... Get the Win 10 mail app to actually sync with exchange servers. It worked on 8.1 and it works with every other mail app I've tested except for this one. (And I've tried every suggested fix I can find on the internet—nothing works.)

Outlook 2010 works fine on this system so that's what I'm forced to use.
