Zimbra and Thunderbird with Lightning
I use Thunderbird for my email client. It's quite speedy and nice. Coming from various places of employment that used Outlook and Exchange, I miss being able to schedule appointments via my email client (of course, with Zimbra, I'm able to do this via the web interface..but I like using Thunderbird for its ability to sort and handle my email).
Enter Lightning, the sunbird-like extension for Thunderbird. So how does one integrate lightning with say, Zimbra? It was rather simple and easy to do so. I'm posting what I did to get this up and running so that others won't fumble through the Zimbra forums trying to piece various posts together finally arriving at a solution after banging heads against the wall repeatedly. Note that I'm assuming you use Zimbra/Thunderbird with IMAP.
Zimbra and Thunderbird Preparation
To get things rolling, install Lightning, the extension from Mozilla AND install the Provider Add on Extension for Thunderbird as well. This Provider Add on Extension also works for Google Calendar (or so it is blogged about often). I'm assuming that you know how to install Thunderbird extensions (which is different than Firefox ones) and that you've been able to install both of those plugins in the order listed.
(Note from p24t: As of 5.0RC1w/L0.5 or L0.7RC1 I did not need the Provider Addon.) (this might similarly apply to sunbird) (it might have been one of those things needed w/ L0.3)
Open Zimbra and browse to your calendar. Right click it and choose "share calendar". You don't need to actually share your calendar because you'll need to provide your login and password initially when connecting...so you'll be able to login as yourself through Thunderbird/Lightening...you just need to copy the URL at the bottom of the pop-up window that appears when you choose share calendar. So copy that URL and switch back to your Thunderbird email client.
After restarting when you installed the extensions above, you'll see the lightening calendar bar in your default view. Click on Calendars and you'll see there is one called 'home'. This is your default one. Let's add a calendar...click on 'New'. Choose "On The Network" for your location.
Next, choose icalendar (ICS) and input the URL you copied from the previous step in the blank and click Next. Give the calendar a unique name and pick a color (I'm partial to green), click next, then click finish. It should prompt you for a login and password...make sure you use your Zimbra Login and Password.
(note from p24t: As of 5.0RC1 and earlier, Calendar events cannot be 'deleted' from Tbird. They must be marked as 'Status: Canceled' through the properties dialog 'More' section (lightning 0.5) or from the menu Options -> Status -> Canceled (lightning 0.7RC1) )

(note from bjquinn: For at least ZCS 4.5.8, there's also a problem in Lightning with appointments created or changed on Zimbra. Once Zimbra changes an appointment, or was the original creator of an appointment, Lightning can no longer update that appointment. Changes in time, etc., revert back to what Zimbra last set it to upon reloading the calendar in Lightning, and the attempted change is never reflected on the Zimbra calendar.)
(note from cedric_galletti : For ZCS 4.5.9, same problem in lightning with appointments... why ? )
- (note: For ZCS 5.0.6 and Sunbird 0.8, I do not seem to have this issue. I created an appointment in Zimbra. I then went into Sunbird and was able to change its title and its date. I then told Sunbird to update its calendars. I then went back to Zimbra and told it to update its calendars. Zimbra applied this change fine. However, if I set a reminder on an appointment in Zimbra, then disable the reminder in Sunbird, the reminder doesn't get removed from Zimbra. Instead Sunbird adds it again from Zimbra during its next update.) --Dslehman 01:52, 16 June 2008 (UTC)
None needed...everything is ready to go.
Tidbits of Handy Information? There is one downside I've found so far. When you create an appointment in Lightning, it creates it as an ICS attached email...so it's not completely integrated. You'll need to send out your appointments like this.
Integrate the ReminderFox extension with Thunderbird to give you reminder pop-ups for all your appointments and tasks :-)
I hooked into my google calendar so I could view my personal appointments (go to DMV, pay bill, etc) as well as my work appointments. Instructions for hooking into google calendar are here.
If you have problems connecting your Zimbra calendar, look at NAT for the problems. Think about opening up the right ports in your firewalls to allow access to IMAP and think of the proper FQDN for your server. You may have to use IP address instead if things are in a DMZ/orange zone.
