Hello, I am new to Exchange Server and Active Directory so please bear with me as my terminology may be confused. Platform: I have successfully performed a new install of Exchange 2003 on Windows Server 2003. The Domain Controller promotion and Exchnage install went well and I now need some help with the initial configuration. Requirements: I have ~10 domains, with 20-30 email addresses associated with each. All users need to be able to login through the protocol of their choice: POP, IMAP, or Web Outlook and I would like to enable the mobile and calendar features for our users and have a public folder for each domain/organization. Questions: (1) The POP3, NNTP, and IMAP services were disabled by the Exchange Server installation. I have set these to automatic to send and recieve email, but does anyone know why they were disabled? (2) What is the correct hirarchy in Active Directory for users/mailbox setup (ie. should each domain have an 'Organizational Unit,' 'Group,' or 'Shared Folder' to contain/be associated with users)? (3) When creating users, does every user have a different name? And if so, how does one resolve the problem of common user names or aliases like info@, sales@ etc.? (4) How do I correctly configure recipient policies for my setup (do I need one policy for each domain etc.)? (5) When I created a new user, they automatically get email addresses at all of my domains (I think this is due to my recipient policy configuration). I am not given the choice of domains to associate the user with. Every user is set to my primary domain by default. How do I change this, so that with the creation of each new user I am given the choice of domains to associate that user with? (6) In Exchange System manager should I create a different store for each domain/organization? Are there any pros/cons I should know about? (7) How do I check mailboxes like 'System Attendant' and 'System Mailbox'? (8) How do I create aliases and virtual users? Is there a central location/flat file where I can edit all users? I realize this is a lot to ask, and answers to any of my questions would be much appreciated. Please CC my email address in your response (info@xxxxxxxxxx). Thank you in advance, Tyrone
