To share your calendar
Sign in to your Microsoft 365 account using a web browser. Select Calendar > Share.
Type the name or email address of the person you want to share your calendar with in the Share with box. This box works just like the To box in an email message. You can add more than one person to share your calendar with.
After you've added who you want to share your calendar with, select how much information you want them to see. Full details will show the time, subject, location, and other details of all items in your calendar. Limited details will show the time, subject, and location, but no other information. Availability only will show only the time of items on your calendar.
You can edit the Subject if you want.
By default, your primary calendar will be shared. If you have created other calendars, you can select one of them to share instead.
After you've finished adding people to share with, setting their access levels, and choosing which calendar to share with them, select Send. If you decide not to share your calendar right now, select Discard.
Each person in your organisation that you shared your calendar with will receive an email message telling them that you've shared your calendar with them. People inside your organisation will have two buttons on the invitation - one to add your calendar to their calendar view, and another to share their calendar with you. The email will also include a URL that can be used to access the calendar.
The calendar will display under PEOPLE'S CALENDARS.
