If these companies would have the users' best interest in mind this would have a simple democratic solution. Take a simple poll on how many people not only want, but NEED, to have these features that have been stripped away. It's one thing to request a new feature addition, it is a totally different issue (with Google, Microsoft, etc.) when we are forced onto a new design for an existing product that removes features we are used to and are integral to our workflow. Having to re-train / re-learn and change methods each time a company decides it wants to do a UI update is beyond frustrating. There are only so many workarounds, none of which are effective in the long run.
Microsoft, this is a simple ask. Return the folder email counts please. Leave it up to a vote.
