With the Zimbra Collaboration Suite, you are able to access your email using 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.

Before You Begin

This guide assumes that you have already installed Thunderbird 2 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.

Accessing your Zimbra Mail with Thunderbird

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.

2. Select Email account in the New Account Setup dialog. Click Next.

3. 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.

4. Select IMAP. Enter the name of your incoming server in the Incoming Server field. If this is your first time using Thunderbird, type the name of your outgoing server in the Outgoing Server (SMTP) field. Click Next.

Note: By default, Thunderbird will not use a secure connection for your incoming and outgoing servers. If your servers require a secure connection, such as TLS or SSL, you must set this after you exit the Account Wizard. To change your secure connection setting, see Changing Your Server Settings.

Note: If you have an existing outgoing server already set as a default, the Account Wizard will automatically use this information. You can change this after you have created your account. To change this setting to the correct outgoing server, see Changing Your Server Settings.

5. Enter your incoming user name from your email address into the Incoming User Name field. If this is your first time using Thunderbird, enter your outgoing user name in the Outgoing User Name field. This is the first part of your Zimbra email address. For example, if your email address is john.doe@example.com, your incoming user name is john.doe.

6. Enter the name you want to call this account in the Account Name field.

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 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.

Changing Your Server Settings

If your incoming server and outgoing server 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.

To change the secure connection settings for your incoming mail server

1. In Thunderbird, go to Tools>Account Settings.

2. Select Server Settings, which is located under your Zimbra email account profile, listed on the left. Your Server Settings are displayed.

3. Under Security Settings, select whether to use TLS if available, TLS, or SSL. Select Never if you do not want to use a secure connection. Select whether to use secure authentication.

4. Click OK to save your settings.

To change the secure connection settings for your outgoing mail server

1. In Thunderbird, go to Tools>Account Settings.

2. Select Outgoing Server (SMTP), which is located at the bottom of the Settings list on the left. Your Outgoing Server (SMTP) Settings are displayed.

  • Description. Enter a name for your outgoing server.

Viewing your Zimbra Calendar using Lightning

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.

To view your Zimbra Calendar using Lightning

Note: These instructions will allow you to view your calendar using Thunderbird with the Lightning Add-on. You will not be able to create or edit appointments, meetings, or events.

1. Open the Zimbra Web Client, and click on the Calendar tab.

2. Right click on Calendar in the Calendar List pane and select Share Calendar from the right-click menu.

The URL of your Calendar is located at the bottom of the Share Properties dialog. Write down or copy this URL.

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 you are 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):

webcal://<USERNAME>:<PASSWORD>@zimbrahost.example.com/home/<USERNAME>/Calendar

10. Click Finish.

Accessing your Zimbra Calendar using Lightning with CalDAV (Only works with ZCS 5.0+ and Lightning 0.8+)

As of some recent build of Lightning (v0.8+), and a recent build of Zimbra (v5.0+) you can also use CalDAV to connect. This appears to fix some problems with deleting events as well.

To use CalDAV, just follow the above steps but use a CalDAV URL of the below form:

http://<USERNAME>:<PASSWORD>@zimbrahost.example.com/dav/<USERNAME>/Calendar
  • (note from alfa_sw33: (ZCS 5.0.10) I use the URL without password:
    https://zimbrahost.example.com/dav/USERNAME/KalendarName
    so you won't have to save your password in cleartext...

Feature Differences When Using Thunderbird

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.
