The new outlook lost all these capabilities - I was stunned to find out that I couldn't search through my emails while being offline
My only explanation is that local search is inherently cross-team and integration-heavy. Consequently, if there's no higher-org prioritization it just molds and breaks over time, as unaddressed integration bugs pile up that cannot be fixed by a single team.
Companies shipping their dysfunctional org chart.
Still, I never thought I'd say that I could do things with the built-in search 20 years ago that I can't today.
