Company B is a new company starting out from resources/personnel in company A. Company B has it's own DC and exchange. How can i go about moving the e-mails for the users in company A to their new e-mails in company B? Some time tomorrow a site to site vpn will be stood up between the companies, but then i'm not sure how that would work afterward since both companies domains arent connected in anyway. Thanks for your time guys.
P.s I can't ask all users to do a PST import.
