I have walked into a SBS2003 std install that was never completed. The customer is not using exchange now and is using Outlook 2010 to do pop3 email at an ISP for their domain name email. No computers have been added to SBS2003 so no authentication is taking place.
My question is:
Can I use Exchange for public folders shared calendars/contacts when an ISP is hosting the email and they don't want the email content within exhange? I would like to avoid an extra inbox tree and just get public folders going if possible.
