How to Directly Import MBOX to cPanel –Simplified Guide

Andrew Watson

Introduction: Migrating MBOX emails into cPanel is a risky task for any user. Firstly, users need to understand the MBOX format that holds all mailboxes in a single file. On the other side, cPanel is a web hosting control panel that gives you a simple GUI and automation tools that make email management simple for all users. With the right steps, users can easily import MBOX to cPanel account within minutes. Users just need to focus purely on the migration process so that they can easily complete this procedure.

Why Import MBOX to cPanel Account?

Moving MBOX emails into cPanel account can be useful because many email clients, such as Thunderbird, Apple Mail, Eudora, and others, store emails in MBOX format. While cPanel’s Webmail can easily open, access, or manage emails directly on the server.

  • If anyone is moving from a desktop email client to cPanel, then users can access or open old email online without relying on email clients.
  • Once users import MBOX files into a Roundcube webmail account, they can access their email anytime, anywhere, not unlike the MBOX format.
  • When users switch email to hosting providers, then access or manage MBOX files, it becomes better in cPanel.
  • MBOX files can be easily searched online, and users can easily manage them within cPanel’s webmail applications.

After knowing the valid reasons to import MBOX emails into a cPanel account, users now want to know the simple and best tricks to export MBOX files. This blog gives you two methods to import MBOX files: the first one is manual, aka the free method, and the second one is the professional method with zero hassles.

Manual Method to Import MBOX to cPanel Webmail

In this method, users need to follow multiple steps that make the migration process complex. I suggest you follow all steps, and please don’t miss any single step while importing MBOX files. Let’s follow the migration process.

Step 1: Configure cPanel Email in MBOX-supportive Email Client

  • Open the used email client that can open MBOX files in a preferred email client such as Thunderbird.
  • Open Thunderbird.
  • Go to Account Settings and then choose the “Add Mail Account”.
  • Enter cPanel email address, password, and server details (IMAP/SMTP).
    • IMAP Server: mail.yourdomain.com
    • Port: 993 (SSL)
    • SMTP Server: mail.yourdomain.com (Port 465 or 587)
  • This step connects Thunderbird with the cPanel mailbox.

Step 2: Use ImportExportTools NG & Move Emails in cPanel Mailbox

  • Once logged in, users now need to go to “Add-ons → Extensions.”
  • Search and install ImportExportTools NG in Thunderbird.
  • Once installed, restart Thunderbird.
  • Right-click on Local Folders in Thunderbird.
  • Go with ImportExportTools NG and use the option “Import MBOX File.”
  • Choose a local MBOX file and import it into Thunderbird.
  • All emails from the MBOX file will show under “Local Folders.”
  • Choose all emails by using [Ctrl + A] in Thunderbird.
  • Drag and drop them into your IMAP-connected cPanel email folders.
  • Thunderbird will sync and upload these emails to the cPanel server.
  • Check all emails and intact attachments.

Note: This method cannot import corrupted or damaged MBOX files into a cPanel account. When users are using this method, make sure they have the best internet connection. If the internet is lagging, then users can lose all previous data. Sometimes this method also takes time when users are trying to import large MBOX folders into cPanel accounts.
