Outlook. Good God do I hate Outlook. Since I started working at my current company, I always wondered why searching through like 2GB of mail in Outlook was slower than searching through +15GB of mail in Gmail. Drove me insane. I have recently set up mbsync and notmuch, along with emacs integration, and now I have practically instantaneous full-text email search. I still use Outlook to read and write mail but don't worry, we will fix that soon. I could go on (plugins are broken on macOS, inflexible UI, etc) but it was mostly the search.
