How to set Outlook 2016 til recent 365 to search All Outlook Items by default

Question

We need a way to set Outlook 2016's/19's/365's Instant Search to search "All Outlook Items" by default.

This has been asked many times. (like Outlook 2016 - Instant Search - How to set it to search All Outlook Items by default)

Telephone support, just told us that we have to contact the programmers. So we do here.

Search worked fine in Outlook 2013. And even it is out of support, many business partners think about turning back to 2013 because only of that search problems.
So please do something. Or tell us how to set it up correctly.
