Gabe_Bratton You posted convincing reasons to switch my Office installation to the "Insider" version of "Current Channel (Preview)." Next questions regarding doing that: For better or worse, I am subscribed to and using the "Microsoft 365 Family" (formerly the "Office 365 Home" subscription). Therefore, if I switch to that Insider build, will I still be able to "submit an In-App ticket," or not? If so, then would you say that the "Current Channel (Preview)" for such a Home-type 365 plan are as (relatively) stable as the Business-type 365 builds are (which are the ones that you said most people inside Microsoft use)? If the answer is yes to both of those questions, then I won't hesitate to switch to those builds, so that I can hopefully help you guys at Microsoft (even in the smallest way) solve this (recurring) Outlook search problem for us. Thanks again for all your help with this problem!
