What is the difference between sharing folders, such as Calendar, in Outlook and delegating access?

There are two ways to work with another person's Outlook folders, such as Calendar, — folder sharing and Delegate Access.

Folder Sharing enables another person to access one of your folders, perhaps while you are on vacation. However, it does not include permissions for one to act on behalf of the other. For example, a person who can access your folders can’t reply to email messages or respond to meeting requests for you.

Delegate Access is an Outlook feature that enables one person to act on behalf of another Outlook user. The most common scenario in which this feature is used is a manager and his or her assistant. The assistant might be responsible for maintaining the manager's schedule, such as creating and responding to meeting requests. Some assistants might also monitor a manager's Inbox and send email on behalf of the manager.
