Set up Calendar Sharing in Microsoft 365
There are a few ways to share your calendar information using Outlook online and Outlook desktop. The option you choose depends on who you want to see the information and how much you want to show them.
Checking a calendar before you schedule a meeting.
See when someone is free before you schedule the meeting
Did you know that you can see someone's basic availability (i.e., free, busy, tentative) when sending a meeting request?
To do this, create an appointment, add your intended recipients, and click Scheduling Assistant. You will then see a set of bars on the timeline which will show all everyone's availability. This is the easiest way to share calendar information because in Microsoft 365, it's already all set up.
