When you are at the Mailbox in GroupWise, go to the menu of folders on the left side. Right click
on Calendar and select New Calendar. You can then name the calendar whatever you want to
call it. To allow others to access the calendar, open the calendar, go to File>Sharing and you
can add people you want to be able to access the calendar by clicking on the button for Shared
with. Then you simply add their names to the list. They will get an email telling them they have
access to the calendar. Once you add them, then you can change what extra rights they have
(add, edit, delete).
