All members of Illinois State University have the ability to manage their Microsoft (Formerly Office) 365 calendars.  By default, Microsoft 365 calendars are set to view “Free/Busy” time.  Free/Busy is being aware that another person has an appointment at a certain day and time.  Please know that each user has the ability to control the amount of detail displayed on their calendar.

Users may manage their calendar settings in the Microsoft 365 portal, or in the Outlook email client. Instructions for each are below:
