You can allow other Exchange users to view or edit your Outlook folders by the "Delegate Access" feature in Outlook, including the default calendar folder.

1. Click "File" > "Info" > "Account Settings" > "Delegate Access".

2. In the opening Delegates dialog box, click the "Add" button.

3. In the Add Users dialog box, add the Exchange users you want to allow to view or edit the default calendar items into the "Add" box, and click the "OK" button.

4. In the Delegate Permissions dialog box, select a permission level from the "Calendar" drop-down list, select "None" for other drop-down lists, and click the "OK" buttons successively to close both dialog boxes.
