I literally cannot understand how Outlook is so awful and unpleasant to use. Constant pauses, regular freezes and a search that will show a document I sent to myself five years ago regardless of search terms but won't surface the perfect match I received yesterday, in the world's most prominent email client.

The only worse software I have to interact with on a daily basis is Adobe's PDF reader, which gives me five popups within one minute of opening it and takes over a minute to do a text search in a five page document.
