Allow compound search operators to work as on desktop AND allow them to be saved as "Smart searches" as on desktop Outlook
In Outlook 365, a VERY useful search like "received:Today AND read:false" does not deliver the expected search results.
On desktop Outlook, this works perfectly as expected.
I also would like to be able to Save a search as a "Smart search" as on desktop Outlook (or in Gmail).
Agree that Advanced Search on Desktop app is far superior to the search capabilities in Outlook 365. I used it all the time when I had the desktop app installed.
