Configuring a shared address book in Roundcube webmail
Learn how to enable a shared (global) address book in Roundcube so contacts can be shared across multiple e-mail accounts in your organization.

This article explains how to set up a shared address book in Roundcube. For example, you can add a user@example.com entry in the shared address book, and all e-mail users will be able to access it from their own accounts.

Configuring a shared address book
To set up a shared address book in Roundcube, follow these steps:

1. Install Roundcube either manually or using Softaculous.
   Note: For instructions on installing Roundcube with Softaculous, see this article.

2. Enable the PHP ldap extension:

   • Log in to cPanel.

   • In the SOFTWARE section, click Select PHP Version.

   • Under PHP Extensions, check ldap.

3. Log in via SSH and navigate to the Roundcube installation directory, for example:

   cd ~/public_html/roundcube

    

4. Install the shared address book plugin:

   composer require johndoh/globaladdressbook

5. Configure the plugin by editing plugins/globaladdressbook/config.inc.php and adjusting the following options:

   • name: The name of the shared address book as it appears in users' contact lists. Default is Shared Contacts.

   • perms: By default, read-only; only admin users can modify contacts. Change to allow regular users if desired.

   • groups: Enable groups in the shared address book by setting to true.

   • admin: Define the admin user, e.g., 'admin' = 'admin@example.com'.

   • autocomplete: Set to true to enable addresses to appear automatically when composing messages.

   • visibility: Controls which users can see the shared address book; default is all users.

6. Access the shared address book:
   Log in to Roundcube with a valid account, click Contacts in the left sidebar, and you will see the Shared Contacts entry (or the custom name you set). From here, you can manage contacts in the shared address book.
