alt Hacker NewsOutlook should be illegal. My biggest pet peeve is that its search doesn't work properly and it misses showing emails. I cannot count how many times I had relative crying calling me that someone is deleting her emails. The emails were there, just incredibly hard to find. Oh and the "Focused" mode that has zero sense.
I don't know how businesses operate using this garbage.
I once got abuse from an Income Tax official for claiming that an email with the details they requested had been sent to them, as the official opened Outlook and searched for it in front of me and couldn't find it! Had to convince the guy to try multiple different keywords before it luckily emerged in the search results.
