Remembering today's date is not my forte. In order to set up an appointment/meeting for tomorrow, I used to check the date by double-clicking on the Windows desktop clock or check my cell phone, and enter the date in the Start time and End time fields. Now I enter “tomorrow“, “day after tomorrow“, “two days after tomorrow“, etc in the Start time and End time fields, and Outlook converts them appropriately. That is very cool.
I found the feature by being a malicious tester. I wanted to crash Outlook by invalid dates, and entered “tomorrow/yesterday/day after tomorrow“, etc as test strings. Voila! Instead a new productivity tip was found.
