Outlook is kind of clever. It will find phrases in emails and offer to do sensible things with them. If it sees "11:00 next Tuesday" it will offer the option to make an appointment for that date.
Thing is, if you get the email on a Monday a human knows that "next Tuesday" is a week tomorrow, not tomorrow. Since if it was tomorrow the sender would have said "tomorrow" rather than "next Tuesday".
If you see what I mean.
Unfortunately Outlook doesn't. Which is why I had some minor palpitations when something I thought was comfortably distant in the future appeared a lot sooner than I was expecting....
