4. Click the Identity tab, and then make a note of the user name.

   3. In the Access Control Settings for Mailbox Store dialog box, click Add.
   4. In the Select User, Computer, or Group dialog box, select the user name that you made a note of earlier, and then click OK.
      
      The Permission Entry for Mailbox Store dialog box appears.
   5. Click to select the Allow check box for Receive As permission.
   6. Click OK until all of the dialog boxes are closed.
