Properties of calendars, and events are the same when you view or edit them as when you create them.
Just as you can edit several objects at the same time, you can edit multiple events at once. When editing multiple events, however, only the Info, and Permission tabs are available.
When editing events, the following rules apply:
For a recurring event, the entire series is always edited.
For an exception to a recurring event, only the exception is changed.
Collaborative services cannot create exceptions to recurring events, but can display exceptions that another application or import creates. Such exceptions can be edited.
If you view or edit a calendar event, and you select the Send email when I finish checkbox, notification email is sent to event participants when you click Finish.
