We sold our business, so I wanted an exact copy of all of the existing emails in our Zoho mail account before turning it over to the new owners.  I opened a new Zoho account and imported all the emails over with file folders intact.  My new Zoho mailbox looks identical to the old one -- including all the messages -- but the Search function is not working.  The exact same search in the original Zoho mail account works just fine.  What went wrong?
