    Default Thunderbird/Lightning: CalDAV vs. ICS

    Now that Zimbra 5.0 supports CalDAV, is there any functional difference if one configures Lightning for CalDAV rather than ICS?

    More generally, if you have a choice of one or the other, is there a best practice recommendation?

    Thanks.

    - Saul

    I'm also wondering the same thing, so I'm replying to hopefully get this floated up top and an opinion from someone.

    isn't the main difference that ics is a protocol for read-only subscribing to a calendar, while caldav is a read/write calendar sharing protocol?

    I don't know the technical differences. I can tell you I have been using the CalDAV functionality of version 6.0.x from Thunderbird/Lightening very successfully.

    There is a major gotcha to watch out for though. Lightening does not prompt for an updated password if authentication fails - it simply tells you there is a problem (and the Error Console suggests it is just temporary.) See

    for details.

    The major difference for me is functionally - ICS works great until you try and delete an appointment - it only deletes locally, so when the calendar reloads, it "comes back".

    CalDAV does not have this issue.
