Use the shared calendar
One of the great things about using a shared mailbox is that anyone who has access to the shared mailbox also has full access to the calendar. You can create, edit, and delete events in the calendar. Use the shared calendar just as you would use your own calendar. Here's a short list of things you can do with the shared mailbox calendar:
Let your team know when you're going on vacation or when you’ll be out of the office.
Create a team meeting.
Edit a calendar event that someone else created.
Cancel a meeting that someone else created.
To access the shared calendar, do the following:
Sign in to your mailbox using Outlook on the web, and then select Calendar.
Right-click Other Calendars, and then click Open calendar.
In From directory, search for the shared calendar you want to open. Select the shared mailbox you want to open, and then click Open.
The shared calendar displays in your Calendar folder list.
