Getting freebusy information from a URL in iCal format

[diegows]

Hi,
Is it possible to configure Zimbra to get freebusy information for non-local users from an external server? This server provides the information via HTTP in iCal format. The users belong to the same domain.

Regards,
Diego

Looks like the answer is "that's impossible" ... :P

Oh, no... some hacking again

I don't think this is what you're looking for but just in case: Bug 36322 – Ability to generate ics freebusy feed as VEVENTs instead of VFREEBUSYs

I think this is what you want: Bug 35304 – Allow access to external users' internet free-busy, similar to Outlook

Note that there are different ways of publishing freebusy. The "normal" way is to use VFREEBUSY objects, which is how Outlook reads internet free/busy. It's also what Zimbra currently publishes. (As a quirk, Outlook/MS call this .vfb whereas Zimbra uses .ifb, but this has no effect on interoperability.)

Bug 35304 is about getting ZWC to subscribe to .ifb/.vfb feeds.

Bug 36322 has to do with the "alternate" way of publishing freebusy--it just uses "scrubbed" VEVENT objects to show when you're busy, without divulging any other information. With this method, any client that can read iCalendar can display the published f/b time as a calendar. E.g. Zimbra or Mac iCal. In Zimbra you subscribe to a published .ics by creating a calendar and then ticking the box (in the properties) that says "Synchronize appointments from remote calendar", with the URL of the calendar.

Yes, that's what I want. So, I'll have to wait
