I am the IT person for a small company that is about to purchase a server. They want the server not only for file sharing and backup purposes but to share their MS Outlook 2003 contacts and calendars. However, they are using an external POP3 e-mail provider and do not wish to have the server do anything with e-mail. I need to tell them whether a server running MS Small Business Server 2003 with Exchange will allow them to do these things, and, if so, what are the specific steps for configuring SBS/Exchange to do this (I know how to create domains and users)? Also, a quick question: They will be having a total of 15 Client Access Licenses (CALs)--does the licensing for SBS allow Outlook 2003 to be installed on up to those 15 users' systems, if they don't already have it installed? Thank you very much for your time and whatever assistance you can provide.
