When an executive or senior manager wants her administrative assistant to screen her email and handle routine items, she can use Outlook to delegate access to her inbox and calendar. Or a user might go on vacation and want some other user to monitor his messages.

To make yourself a delegate of a user’s mailbox, open the Active Directory Users and Computers snap-in, and then follow these steps:

• Right-click the organization domain name, point to View, and then click Advanced Features.
• Click the Users container (or the organizational unit where the user is located).
• Right-click the user account, and then select Properties.
• Click the Exchange Advanced tab.
• Click the Mailbox Rights button.
• In the Permission window, click the Add button to add yourself to the list of those whose are allowed to access this mailbox.
• In the next Permission window, click to select the Allow check box under Full Mailbox Access, and then click Apply to implement the changes.
