Migrated a number of users from 2007 to 2013. All OK apart from one user (who had the largest mailbox). Know he can recieve newly created emails but
no-one can reply to an email otherwise this error occurs. Tried moving back to 2007 but, worryingly, this does not seem to work.
Delivery has failed to these recipients or groups:
