The time for the meeting is sometimes not shown on the top when I create a meeting.
What is displayed in the calendar depends on how much space is available. If the event is very short, e.g. 30 minutes, there is usually only one line of free space which is used for displaying the event name. If you’d like to see the time for short events as well, you can zoom in using Ctrl + mouse roll which makes space for also displaying the time.
You nailed it, Maurice! Thank you!
