In Exchange 2013 there might come a time when you need to grant full access to a users mailbox. A PA might need access to his/her managers mailbox or another user needs access to a mailbox.

- Once you have the properties window open for the user, the general page will show.
- Click on the mailbox delegation tab on the bottom right.
- Now click the + button under Full Access.
- Once you click the + button the window above will show.
- Select the user that you want to have full access and either double click the user account or select it and then click on the add -> button. this will insert the account into the text box highlighted.
