Hi,

i am running Zimbra 5.0.18 on Ubuntu8.04 amd64.
having Thunderbird 2.0.0.22 with Lightning 0.9 clients.

the Urls are connected via https Apache Reverse Proxy.

Read/write works with ics and caldav for the own calendar.

There aren't any write's possible to a shared Calendar, it had fist a space included with %20 which i removed.

Read's are possible on the shared calendar, but when modify i get:
MODIFICATION_FAILED

But the Calendar has write permission, as it works within the Webui.

in Lightning i removed currently the private Calendar as there seems to be an bug within TB, when using HTTPS and more than one Calendar to the same server?

but still no write permission.

any ideas?
