There are two ways to work with another person's Microsoft Outlook folders -- folder sharing and Delegate Access.
Note: A Microsoft Exchange Server account is required.
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 cannot reply to email messages or respond to meeting requests for you.
If you'd like someone else to be able to perform these tasks, then you should use the Delegate Access feature. 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, including creating and responding to meeting requests. Some assistants might also monitor a manager's Inbox.
You can find out how to set up Delegate Access.
