Several users had a complaint: the appointments on their monthly Outlook calendar disappeared and were replaced by 3 dots. (Using the classic Calendar in Office 365 business accounts, users will see a number, not dots.)
I am no longer able to see events that I've saved to my Outlook calendar. No matter how many times I create and save an event, when I return to the calendar screen, all I see under the date is three dots. When I go back to February and January, I see all my events under the dates on which they occurred. Why can't I see them now?
This is caused by the number of calendar weeks March needs and the screen is too small to show everything. March covers 6 weeks, beginning on a Friday and ends on a Sunday. February needed 5 calendar weeks, so the cells are taller, leaving more room for events to display.
The height of the browser window also has an effect. If your monitor or window is larger, you'll see the events, if its smaller or you don't have the window full screen, you'll see the dots.
Setting the calendar week to start on Monday will solve the problem for March (and June), and only 2 months going forward will be affected: they start on Sunday and end on Tuesday.
Lowering the browser zoom % will also solve the problem.
Outlook desktop should show at least one event each day, unless your screen is really small (under 600 pixels high).
