Transferring Horde email to Gmail can be accomplished manually, but it involves several steps that can be challenging. First, you need to export your Horde emails as an MBOX file. This process typically requires accessing the Horde webmail interface, selecting the emails you want to transfer, and using the export option. Once you have the MBOX file, you can import it into Gmail using Google’s Import feature. However, this method can be time-consuming, especially if you have a large volume of emails, and you may encounter formatting issues or data loss during the transfer.

To simplify the process, consider using the Cigati IMAP Backup Tool. This software streamlines the migration by allowing you to transfer Horde emails directly to your Gmail account without the need for intermediate file formats. It supports bulk email transfers and ensures that all your data remains intact, making it a more efficient and user-friendly solution for migrating emails.
