I'm trying to find information on moving a mailbox from (gasp)
Exchange 2010 to Exchange 2003. Same domain, forest (afaik), same
everything just 2 servers. Lets call them Exchange2010 and
Exchange2003.

The destination database is on Exchange2003 and is just the default
priv1.edb, "Mailbox Store." I can't figure out the shell command
syntax. Help?
