MicrosoftJust a couple comments on the desktop version of Outlook (apologies if any if this is covered above; I didn't see it, if it was).
1) For Insiders, the search box was moved to the new location around two months ago, though I've noticed that it sometimes relocates itself back to the traditional location from run-to-run. Was moving it in advance of "Coming Soon" unintentional?
2) I strongly suggest that you ultimately provide an option for people to stick with the traditional location. Many prefer that. I'm not speaking of "Coming Soon" here but later on, when it's rolled out to everyone. If you don't, then this will inevitably become a top request.
3) I hope the "Coming Soon" button is more consistently available for Insiders. At least here, most of the time last year during the window of time when it was widely available to Insiders (this was months before it was intended to go away) that the button disappeared from the UI after a few weeks and therefore none of the UI elements were available for testing. And, unfortunately, there was no way to get it back for those who wanted it, even via Registry (this is not to be confused with the Registry entry that you provided to make it go away).
