This is a proof that Microsoft and Linux are friends now.

Visual Studio & Visual Studio Code.

Outlook is quite bad. There's no way to enable week numbers in the week view. And once you accidentally decline an occurrence of an recurrent event, there's no way to get it back, without having to trouble the meeting organizer to resend the request, or create the event manually yourself. In addition, Outlook is ugly and I strongly dislike how the calendar and inbox are combined in the same application. To me, e-mail and calendar are two completely different things, and there should be a way to open the calendar separately, without the distraction of any incoming e-mail.
