Lightning is an Add-On for thunderbird to show remote calendars e.g. of our Zimbra Mailserver. Open Thunderbird and switch to the Calendar view (lower left corner): lighning02.png Move the mouse over the still existing local Thunderbird calendar Home, press the right mouse button and choose New Calendar. Follow the next screenshots. lighning03.png lighning04.png Replace the username in the URL with your own. lighning05.png lighning06.png

You can configure more than one calendar. To find out the right URL: Switch to Firefox and call . Choose tab Calendar. Move the mouse over the calendar name on the left side. Right mouse click, choose "Share Calendar". Copy/paste the Calendar URL (highlighted in the screenshot). lighning10.png

If you want to delete an appointment, best do this via web interface in Firefox. If you really want to delete appointments in Thunderbird, you have to: Open the event Choose: Option > Status > Canceled > Save and close. Delete the event with: right mouse click > delete. If you delete the appointment without prior canceling, the appointment will be deleted in Thunderbird, but not in Zimbra. Calendar gets out of sync: From time to time it happens that Thunderbird/Lightning don't show any new appointments or changes. Delete the calendar in Thunderbird (you only delete the connection, not the calendar itself). reconnect the calendar. Reminder If you create a new appointment in Tunderbird, the default is not to remind you. If you create a new appointment in the Zimbra webinterface, the default is to remind you - take care about many unwanted reminders which will appear in Thunderbird suddenly!!!
