Previous environment: x1 Exchange 2000 Server on Windows 2000 Server SP4
Current environment: x1 Exchange Server 2003 SP2 on Windows Server 2003 R2 - OWA, Outlook RPC over HTTPS, mailbox server, etc.
The Exchange 2000 server has been brought out of semi-retirement, shipped to the USA, brand new mailbox stores and storage groups were created, and users from a different Exchange ORG and AD forest have been migrated to this server. Is it possible for remote users on this server to access their mailboxes via OWA? Or is a Front-End Exchange server mandatory?
