We have a Small Business Server (SBS) Windows 2003, and we need to setup a shared outlook calendar using exchange (comes with the SBS), however my client does not want to use exchange mail. In other words, they would like to use Outlook to send an receive emails using some hosted web mail service (using POP) but have the Outlook calendar shared among users using exchange on local SBS server. All users have domain accounts configured. Is this possible to do?
