If you want to disconnect the SharePoint calendar from Outlook, here's what you would do:
Right-click the entry for the calendar under Other Calendars
On the shortcut menu, click Delete "SharePoint Calendar Name"
(where SharePoint Calendar Name is the name of the shared calendar).
This will remove the copy of the calendar from Outlook and from your own computer. It will not affect the calendar on the SharePoint site. If you change your mind and want to reconnect, you can always do that by starting from the SharePoint site again.
Tip If your aim is to temporarily hide the SharePoint calendar from view, simply clear the check box next to the name of the SharePoint calendar (in the Navigation Pane under Other Calendars).
Not sure you'll remember all of this? Don't worry, we're not expecting you to. The Quick Reference Card at the end of this course includes summary steps for everything we've talked about in the course.
