There are two ways to work with another person’s Outlook folders — sharing folders and entrusting someone to act on your behalf (delegate).
- Folder sharing lets other people access one or more folders. However, it does not include permissions for them to act on your behalf. For example, a person who can access your folders can’t reply to email messages or respond to meeting requests for you.
- Using Delegate Access , you can give someone permission to act on your behalf. For example, you might have an assistant that you want to create and respond to meeting requests for you. Some assistants might also monitor a manager’s Inbox and send email on behalf his or her behalf.
