BB Curve :: Email Accounts Deleted By Mistake In 9300

i deleted my three personal email accounts by mistake in Bb curve 9300 O6( update) network independent.i actaully just activated blackberry internet service account and suddenly all three accounts were gone.Though i never made any account in blackbery internet service. now all emails recieved till date from those three accounts are appearing together in Message box along .i again created those three accounts again.they are working well but i can not get earlier mails ,now in message box , back into the newly created email accounts.So to look for ols mails,i need to go back to message box.
