Hello,
I believe I'm having the same problem as you are.
We use SugarCRM internally and some appointments are made on Sugar's calendar. This worked great together with Mozilla's Sunbird extension (calendar extension for Thunderbird), and with Apple's iCal application also.
The problem is that now that we moved to Zimbra, we cannot subscribe to SugarCRM calendars anymore.
Whenever we subscribe to a SugarCRM (using Sugar's iCal patch) such as:
http://SUGARHOST/sugar/ical_server.p...=USER&key=PASS
Zimbra returns this error to the user:
"Appointments could not be retrieved. Make sure the following URL is a valid ICAL feed: http://SUGARHOST/sugar/ical_server.php?type=ics&user_name=USER&key=PASS"
Looking at the logs in /opt/zimbra/log/mailbox.log, we can see:
