Via the bugzilla entry mentioned earlier in the thread, I've learned that you can access a free-busy weekly calendar with blocked-out busy time via
http(s):// server.domain.com/home/username?view=week&fmt=freebusy
(Substitute day for week if you like.)
This is close to ideal. But I wonder if I can
1) Require authentication to access http:// server.domain.com/home/username?fmt=freebusy
It would be acceptable (minimally) if the authentication were via a single username/password set at the server.
2) Give users the ability to selectively provide access to outside parties.
In other words right now when I share a calendar with an External Guest, it seems I can't keep them from viewing the details of my calendar. I want to have the same level of control that's offered by right-click/Share Calendar, while sharing only my FB info as a web page.
3) Do the same as (2) but provide my FB in a format that's accessible to Outlook's Internet Free/Busy Feature.
See
How to use the Internet Free/Busy feature in Outlook 2007 and in Outlook 2003 under
How to set the free/busy search path for a specific contact. In other words I want to make it possible for external Outlook users to access my FB when they propose a meeting with me, but I don't want to let them see the details of my Calendar.
Doable? Should I file an RFE?
