Share a calendar with others in new Outlook for Windows

1       From the navigation pane, select   Calendar.


2       On the Home tab, select Share calendar, and if you have more than one calendar, select which calendar you want to share.


3       Type whom to share with in the Enter an email address or contact name box. If the person's name appears in a list, select it, otherwise press Enter.


4       After you've added the person you want to manage your calendar, select the drop-down list next to their name, and choose the level of access you want them to have.

                Select Can view when I'm busy to give them permission to see only when you are busy, but not the details of items on your calendar.

                Select Can view titles and locations to give them permission to see when you're busy, plus the titles and locations of items on your calendar.

                Select Can view all details to give them permission to see all details of items on your calendar. This option allows others to view your calendar but not make changes to it.
Note: If you want to grant permissions that allow a user to edit your calendar, or can respond to meeting requests on your behalf, see Calendar delegation in Outlook.

6       The person you're sharing a calendar with will receive an email invitation to share their calendar. Once they accept, they can add your calendar to their own view.
