Background: Since version 38 the Lightning calendar extension is bundled with Thunderbird, meaning the Lightning extension comes with Thunderbird and you do not need to download the extension. For versions prior to Thunderbird 38 you will want to download the extension from Calendar versions. E-Mail: This is the email address Thunderbird uses to send invitations for events. Refresh Calendar: This is how frequent Thunderbird will check for changes on the calendar details. Read Only: If checked, this makes the calendar not editable by default. This is very nice for shared office calendars that you don't want to edit by accident.

  • 6.1To view your Zimbra Calendar using Lightning and CalDAV

With Zimbra Collaboration Server, you are able to access your email using the Mozilla Thunderbird messaging and collaboration client. Optionally, you can view your Zimbra Calendar using the separate Lightning Add-on for Thunderbird.

This guide shows you how to access to your Zimbra Mail and Calendar using Thunderbird 2 with the Lightning 0.5 Add-On.

This guide assumes that you have already installed Thunderbird and, optionally, have already installed the Lightning Add-on. For more information on downloading and installing this software, go to Mozilla's Thunderbird page, http://www.mozilla.com/en-US/thunderbird/ .

To access your email, you must have the following information:

• Your Zimbra email address and password.
• Incoming mail server. This is usually in the form of mail.domain.com.
• Outgoing mail server (SMTP). This is usually in the form of smtp.domain.com.

Your system administrator will be able to give you this information if you do not already have it.

To access your Zimbra Mail, you must first create an account in Thunderbird. The following steps guide you through setting up a new account in Thunderbird.

To create a new account in Thunderbird

1.- Go to File > New > Account. This will open the Account Wizard.If you have just opened Thunderbird for the first time, the Account Wizard will automatically open. Enter the name you want to appear in the From field of your outgoing emails in the Your Name field. Enter your Zimbra email address into the Email Address field. Click Next.

2.- Thunderbird will try to get the Autodiscover information using some different technologies, after a few seconds Thunderbird will prompt with some Autodiscover information, if the data is not what you expect, you mus click in the Manual config button:

3.- Select IMAP o POP3 for the Incoming Email, you must be change the Server Hostname with your correct information. Introduce the SMTP Server Hostname as well. Zimbra recommends always use secure channels, so you can select SSL for both, IMAP/POP3 and SMTP.Note:' By default, Thunderbird will use a secure connection for your incoming and outgoing servers using TLS. If your servers require a secure connection, such as SSL, you must set this after you exit the Account Wizard. To change your secure connection setting

4.- Verify that the information displayed is correct. If any information is incorrect, update the information. When the account information is correct, click Done.

Your settings are saved, and the Account Wizard closes. You are now able to access your Zimbra Mail.

If your incoming server and outgoing server use not secure connections, you will need to configure this before you are able to access your mail. Additionally, if you did not specify an outgoing server when you were setting up your Zimbra email account, you will not be able to send outgoing messages yet. See the next section in order to change your server settings.

If your incoming server and outgoing server doesn't use secure connections, you will need to configure this before you are able to access your mail. Additionally, if your Outgoing Server (SMTP) is not set to the correct server, you will not be able to send outgoing messages. Use the following directions to change your server settings.

The following steps show you how to read your Zimbra Calendar with Thunderbird using the Lightning Add-on. These instructions assume that you have already installed Lightning 0.5 at least, Thunderbird comes with Lightning since the version 38.

To view your Zimbra Calendar using Lightning and CalDAV

The recommended way to connect your Zimbra Calendar and Thunderbird is using Lightning and CalDAV. You will be able to do all the typical actions in a Calendar, and you will synchronize with your Zimbra Server, as follows:

• Create appointments
• Edit appointments created from the Web Client or another device
• Delete appointments
• Move appointments
• Dismiss appointments
• etc.

Zimbra Calendar and requirements

Since Zimbra Collaboration 6, you don't need any additional step or configuration in your server. You need to know the Calendar name that you want to use in the CalDAV client. The final URL to use in the CalDAV client would be:

You can also add your credentials into the URL. Note that this includes your password, which may not be recommended.

For example, this uses Calendar2:

Thunderbird instructions

• 1. Click on the Calendars tab, in the top left of your Thunderbird application.

• 2. Click right-click New. A Create New Calendar dialog will display.

• 3. Select On the Network. Click Next.

• 4. Select CalDAV. In the Location field, enter the URL of your Zimbra Calendar, and click Next.

• 5. Enter a name for your Zimbra Calendar in the Name field. Select a color for your Calendar, and click Next.

• 6. Enter your username and password, if prompted.

• 7. You will be able to see all the Appointments in your Zimbra Web Client, and you will be able to edit them, delete them, etc.

Shared Calendar & Tasks in Thunderbird

You can use as well all the Zimbra sharing power with Thunderbird and CalDAV, for example: Imagine that you are the Responsible Person for one Department and you want to create a Calendar per each Technician, and a Tasks List, like in the next diagram:

The Responsible must create each Calendar or Tasks List and share with the rest of Technicians, giving them the read-only or read-write permission. You must be careful with the location of the Calendars, or Tasks List, for example if you create the Tasks List called Technician Bob, inside your own Task List, the URL to share will be > https://zimbra.example.com/dav/RESPONSIBLEUSERNAME/Tasks/Technician%20Bob You can see here an example:

In this example, the Responsible creates a Tasks List for Technician Bob, is the same procedure for Calendars as well. Go to the Responsible Tasks, and right-click > New Task List

Then, write the name for the Tasks List, in this case Technician Bob, you will need later the %20 in the URL, if you can, it's much better to use - or _ instead space.

Edit then the new Tasks List with right-click > Properties and select Add share

In the email field, select the Bob's emails address, and select the role you want for Bob, read-only or read-write.

Now, you can tell to Bob the URL that he must use to connect to the shared resources, Calendar, Tasks, etc. The URL will be the Responsible one, like https://zimbra.example.com/dav/RESPONSABLEUSERNAME/Tasks/Technician%20Bob even if the URL points to the Responsible, because Bob has access to that concrete resource, Bob just need to write his credentials when Thunderbird asks about them.

Log trace when sync

When the appointments are pulled from the Zimbra Server to the CalDAV client, you will be able to see the next log traces in the /opt/zimbra/logs/mailbox.log. You can see that these came from Thunderbird with Lightning:

Read-Only, not recommended - To view your Zimbra Calendar using Lightning and ICS

8. Enter a name for your Zimbra Calendar in the Name field. Then, select a color for your Calendar. Click Next.

9. Enter your username and password, if prompted.

Note: If you are not prompted, and access to the calendar fails, a workaround that I found is using a Calendar URL in this scheme - not elegant to put a password inside this URL; but the only way that worked for me (HenningSprang):

10. Click Finish.

If you have used the Zimbra Web Client, note that the following features are different when using Thunderbird as a client.

• To view mail folders that you have created using the Zimbra Web Client, you must subscribe to them.
• Thunderbird may not always expunge deleted items or old drafts. These messages will be visible if you access your mail using Zimbra Web Client.
• Lightning does not use notifications for upcoming events and meetings.
• The Lightning Add-On may not automatically refresh your Zimbra Calendar. To see the most recent version of your Calendar, right-click and select Reload Remote Calendars .
• Lightning only records a single set of authentication information for all remote calendars. If you have already set up access to another remote calendar using Lightning, you may encounter authentication errors when attempting to view your Zimbra calendar.
