Office 365 is crap too. Outlook web app is significantly slower than Gmail. Outlook doesn't even support labels natively, and their filters are miserable. Outlook web app still is far from feature parity with their desktop app and their desktop app doesn't work on Linux.
Outlook calendar automatically deletes the entire series when you try removing past events. I had a manager that left recently and therefore they cancelled a series. Rather than keep the previous events so that I could go back and see what I was doing on a particular day, it just removed the entire past series from everyone's calendar like they never attended.
