Here's the procedure on how to assign permission to a calendar.

 

For example, sharing your own calendar.

• Open Outlook.
•  In the left side column, click the Calendar
• The right side column, will change to your month calendar schedules. In January 30 - February 05, 2011 right click, then select Properties. This will open the Calendar Properties.
• In Calendar Properties, click Permissions tab.
• Click Add to select a user. Click Add, then OK
• In Permission Level pull down menu, select the permission you want to assign to the user. For example, Reviewer (read only), Editor (power user), etc.
• Click OK to complete.

If you gave permission to John Doe to see your calendar schedules. Here's how to add your calendar to John Doe's Outlook profile.
