Google Calendar App with my Zimbra

Postby cjm51213 » Fri Jun 12, 2015 12:45 pm

Hi Folks,


I seek to register my Zimbra calendar for use with Google Calendar. This is done by adding the Zimbra calendar "by URL". I have determined through calendar properties that my URL must be https://<server:port>/home/<email address>/Calendar but that will not work in the Google Calendar application. Google accepts it as a good effort, but never actually receives any data from Zimbra. If I enter that URL in the browser address bar, I get 404: Problem accessing /service/home/<email address>/Calendar. Reason:  no such item


For clarification "<email address>" is a token and not the literal string I used, as is "<server:port>".


Is this:



  • My lack of understanding, meaning I'm just entering nonsense

  • Configuration failure, meaning the Zimbra server has not been instructed to share the calendar

  • A bug


Thanks for the help,


Chris.

Update: I have a URL, which when manually pasted into the browser address bar prompts the return of "Calendar.ics". and that is a step forward. So, I now believe that I have no configuration problems, but it is still not clear why the Google Calendar app responds with "loading..." and then nothing... Perhaps, I simply need to be more patient. Maybe tomorrow? That's not very promising...

From my experiments, it looks like Google Calendar expects to not need authentication to access the calendar - which is probably the root of your problem. Nor can Google Calendar work as a CalDAV client from what I can see. https://code.google.com/p/google-caldav-issues/issues/detail?id=89 and https://productforums.google.com/forum/#!topic/calendar/8Et0DrmzYqQ

Hi Gren,



Those two references are spot on, and lead me to believe that I won't be able to do what I want. Damn shame. Even if I share with an "external user", meaning read-only, no need for credentials, there is no display, although it almost looks like it is going to work.



But, what is happening here; This looks suspiciously like CalDAV sync: https://support.google.com/calendar/answer/99358?hl=en



So this raises the question, who is actually not CalDAV compliant? Google Calendar or Zimbra?
