I am looking to HOST exchange services for my customers to cut there cost implementing MS Exchange server, as you know Exchange is not cheap but the CALS are...
Does anyone know of a good way to do this?
I know how to host multiple SMTP domains, but cannot get my head round hoe to configure the clients etc..
For example 2 companys ABC.COM / 123.COM ... I can configure exchange to accept mails from these domains, no problems. I want to configure MS Outlook to retrieve their messages only. If i configure a signle AD domain i.e. MAILHOSTING.COM and then create the users with specific UPN's for their logins... How can i restrict the GAL not to show the other company's Accounts? and restrict them to only their own GAL?
Is this the right way to configure the server ?
Thanks in advance!!
