Microsoft has fixed a bug in Outlook where selecting multiple calendars would display incorrect meetings and timeslots. Microsoft says that this issue could possibly be caused by low screen DPI or dot density, among others.
After a user selects multiple calendars in the calendar pane, they may find that the wrong timeslot/meeting is selected when they click on a meeting while viewing multiple calendars. Calendars where the user has full access (which are not automated) may display incorrectly.
Possible causes include:
- Low Screen DPI, or Outlook is not optimized and the window is relatively small in size.
- A calendar was added or selected in the Calendar pane.
- Both non-working hours and working hours are displayed in the same view.
