An organization that has been using OWA(for its remote offices) now intends to use Microsoft Office Outlook to send and receive intra and inter mails on the same domain.
They are- at the moment- configured thus:
1. The HQ uses a live IP address on its server; so that remote offices can point to the server
2. Suffice to say that remote offices only requires internet access to access their mails through
OWA. And their mailboxes reside at the HQ
I need to know the upgrade required
What are the changes required on their domain?
How do i go about installation/configuration to achieve this?
