summary
You can install a number of webmail software packages on your Plesk server and make them available to users. You can also redirect users to an external webmail service.
In this topic, you will learn what webmail software is supported in Plesk. You will also learn how to register an external webmail service, and also how to make certain webmail services unavailable to users.
## Supported Webmail Software
**Plesk for Linux**
- *Roundcube* (included in the “Recommended” preset)
- SOGo Webmail (can be installed as a Plesk extension)
**Plesk for Windows**
- *MailEnable Web Client*, *SmarterMail Web Client*, and *IceWarp (Merak) Mail Server Web Client* (come with the corresponding mail servers)
Note
If you offer Roundcube to your customers, keep in mind that Plesk backups do not include backups of the Roundcube database. This means that Roundcube data such as customers’ calendars and contacts is not restored upon restoration of selected subscriptions or the entire server.
## External Webmail Services
To register an external webmail service:
1. Go to **Tools & Settings** \> **Webmail** (in the **Mail** group).
2. Click **Register Webmail**.
3. Specify the following:
1. **Webmail service name**.
2. **Webmail service URL**. Specify an address that begins with the `http://` or `https://` prefix.
3. Leave the **Available** checkbox selected to make the registered webmail service available for selection in hosting plan settings.
4. Click **OK**.
To change the properties of an external webmail record:
1. Go to **Tools & Settings** \> **Webmail** (in the **Mail** group).
2. Click the appropriate link in the **Name** column.
3. Make the required changes and click **OK**.
To make a webmail service unavailable for inclusion into hosting plans:
1. Go to **Tools & Settings** \> **Webmail** (in the **Mail** group).
2. Do either of the following:
- To make a service temporarily unavailable without actually removing it, select the corresponding checkbox and click **Disable**.
This works for installed webmail software packages and for links to external webmail services.
- To permanently remove a service record, select the corresponding checkbox and click **Remove**.
This way you can remove only links to external webmail services. Installed software packages can be removed only by means of Plesk Installer (**Tools & Settings** \> **Updates**).
