Everything that users store within CrossBox is counted against their cPanel hosting package quotas.

Password Change Syncing
When a user changes its e-mail password via cPanel, user's CrossBox password is also changed, and vice versa.

Hosting Account Suspension
When a cPanel hosting account is suspended, CrossBox users of that hosting account are also suspended and automatically logged out of the application.

Email Account Suspension
When a cPanel email account is suspended, CrossBox for that email address is also suspended and the user automatically logged out of the application.

Hosting Account Termination
When a hosting account gets terminated, CrossBox for that account is also deleted, including users' CrossBox data.

Done automatically by cPanel's native Backup System. You can also use any other backup solution for cPanel and it will work out of the box.

WHM Feature Manager
After the installation, CrossBox is available as an option in WHM's feature list. This gives you total control over who has access to CrossBox. For example, you may enable it for everyone or only for customers that use a more expensive hosting package.
