As a user with access to other user's mailboxes, you can use your IMAP account to view the shared mailboxes you have access to. To do this, you need to configure a new account for each shared mailbox. Follow the instructions on how to create a new IMAP client account in the email client of your choice, however, as a username, type your username in the following format: YourUserName|SharedMailboxUserName using your own password.
Dynamically generated configuration steps for the supported IMAP clients can be found via the web interface under:

- GFI MailArchiver 2013 or 2012: Email Client Access > Configure IMAP Access
