# -- Convert mailboxes to mix format for every user
#
# -- Author: Bob Atkins, DigiLink Network Services
#
# -- First Release : 2/16/08
#
# -- Revised:
#	8/25/09 - Added options to convert a single user. Added checks for already
#		converted mix format boxes so that they are not re-converted.
#	9/9/09 -  Create user INBOX after the conversion if it doesn't already exist.
