Calendar Permissions

The new calendar inherits permissions from the parent site and will be accessible by anyone already having permission to the site. 

To create unique permissions to the calendar (different from the site permissions), use the following directions:

1. Choose Settings - - > List Settings - - > Permissions for this List
2. Choose Actions - - > Edit Permissions  (to stop inheriting permissions from parent)
3. Choose New - - > Add Users (to specify users and permissions to the calendar)
    
   

Connect the Calendar to Outlook

From the top menu select:  Actions - - > Connect to Outlook

Using the SharePoint Calendar from Outlook

1. Open Outlook
2. Choose Calendar from the left navigation pane
3. Check the box next to the appropriate calendar
