Microsoft Outlook 'Calendar Sharing Service` benefits, drawbacks and alternatives?

Question

I have users who want to share their calendar with external users. What is the best way to approach this?

Outlook2003 has the Calendar Sharing Service, but I don't know if it's updated or replaced by something better in Exchange 2010 / Outlook 2010

Answer 1

There is a new Exchange 2010 feature in SP1 that's great. Called Internet Shared Calendars. Your OWA servers can allow anonymous access to a sub-folder where you can access Calendars via webpage or .ics syncing. Admin has policy control over what details are allowed and user can enable/disable their public calendar and a few other options. Users get a button in Outlook 2010 Calendar View that takes them to the web page to change options.
