Hi Jeff, be sure Mail is quit on both computers, then...
On Mail these 2 folders...
(Could be a different folder here if you chose such in Mail Prefs)
... only the plist is separate.
I have a similar Mailboxes transfer problem, except I'm trying to transfer PPC Mailboxes on a G4 running Tiger Mac OS X 10.4.11 to Mailboxes on an Intel PowerBook Pro running Mac OS X 10.6.8. Do I use the same copying/replacing files you recommended above, or do I copy and replace different plist files?
Thanks for your help.
