i am not very experienced in exchange so pardon my ignorance. i have two domains: one is a .local domain used on the LAN and second one is a .com domain that's located in the datacenter. domain in the datacenter has an exchange server running. now if i want to add users i have to add them to the local domain, not create a mailbox there and than add the same user on the .com domain and this time create a mailbox. is there a way i can limit this to only single step? thanks in advace...
