In a test environment I wan't to install a new Exchange 2010 as a "host" for multiple email domains where the users will connect externally via Outlook/OWA.
My server domain is named ICACELL.LAN
I have 5 different domain names each with approx. 10 different users.
Do I have to create all these approx 50 users as users in ICACELL or is it somehow possible to create these only for Exchange?
It would be really need if I could create groups corresponding to the emain domains and then just create users within these.
I am a Microsoft Technet subscriber so I have access to most of the Exchange versions.
I would appreciate any input :-)
