Plesk currently has two different email managers, these are Roundcube and Horde.

In this tutorial we will explain how to easily and quickly change the manager.

First, it is necessary to access your Plesk panel and go to the subscription in which you want to change the email manager.

Once inside, click on Mail in the top menu bar.

In the next window we will have to click on Mail settings

In the next window we will see the domains that we have in that subscription, in our case we only have one, so we will only see that one.

We must click on the domain.

In the next window, in the Webmail field we can select the manager from the dropdown and click on Apply.
