The calendar sharing feature introduced in Outlook Web App 2010 (OWA) allows a user to grant access to their calendar to another user.
To access the option, click on the Shareoption when in the Calendar and then on Share This Calendar. You’ll then be able to select the user(s) that you want to share your calendar with and define the level of information you want the recipient to be able to see in your calendar.
The recipients see a message as shown below. To access the calendar, they simply click on the Add This Calendar link. OWA will then add the calendar to the list of available calendars and the user can then access your calendar whenever they want by simply clicking on the calendar’s entry to instruct OWA to open it.
Set-MailboxFolderPermission -Identity alias:\Calendar -User UsertoGetRights -AccessRights Editor
For example, if my alias is “TRedmond” and I want to grant access to the user “Redmond, Eoin”, the command is:
Set-MailboxFolderPermission -Identity TRedmond:\Calendar -User ‘Redmond, Eoin’ -AccessRights Editor
Once a user has been granted Editor permission, they can edit or add items to a calendar. Note the “Notify” checkbox. If set, the user who owns the calendar will receive an “Appointment Created Notification” as a new message in their inbox to provide them with details of the new event.

Calendaring sharing is a nice feature of OWA 2010. It’s just a pity that the developers left out the ability to grant editor access to a calendar – but now you know how to do it behind the scenes!
