I am using Outlook 2010, but I am unable to find a way to search through all the sub-folders of a shared mailbox. I believe this may be a limitation of the software, but I sincerely hope I am wrong.
Open the advanced find (Ctrl+Shift+F) and, using the browse option button, select the shared mailbox and then check the check box below
