MBOX is a widely used file format supported by several email clients to store email messages. On the other hand, Horde is a web-based email application offered by many webs hosting providers, featuring tools for email management, contacts, calendars, and more.

However, Horde does not support direct importing of .mbox files. To move your emails into Horde, you’ll need to follow a few additional steps. In this guide, we’ll explore practical methods to help you successfully import MBOX files into Horde webmail.

Let’s dive into the solutions in detail.
