Migrate Emails from cPanel to O365: Admin Migration Guide in 2026
Query: Hi everyone,
What’s the most straightforward way to migrate emails from cPanel to O365, bearing in mind that we’ll be using different emails and domains (and the cPanel emails will mostly be used for reference and archive)?
Summary: This article explains the two best methods to migrate cPanel email to Office 365 in easy steps. Here, we will discuss the step-by-step procedure that allows you to migrate all the mailbox emails from cPanel to an Office 365 account. Moreover, you can also try the Aryson IMAP Email Backup Tool, which will enable users to perform email migration from multiple cPanel accounts to Office 365 efficiently.
Why Migrate Emails from cPanel to O365?
There are various advantages of Office 365 that compel users to move cPanel emails to Microsoft 365 accounts, including:-
- Outlook 365 has a monthly or user-based subscription to access the mailbox data.
- It could work on the cloud, PC, and mobile devices.
- O365 offers an interactive interface for better workflow.
- The advanced filters and Search option help users operate quickly.
- Microsoft 365 offers multiple built-in applications to store the data.
Well, now we know what cPanel and Office 365 are and the main reasons for migrating cPanel mailbox emails to Microsoft Office 365. So, now it is time to move on to the solution to overcome or eliminate the issue.
02 Best Ways to Migrate cPanel Email to Office 365
In this section, we will discuss the right approach to perform mailbox migration from cPanel to Microsoft 365. So, let’s read the steps of the method.
Method 1: Manual Two-Step Migration (MBOX Download + Import)
This approach works if you don’t have admin access to the Exchange Admin Center or if you’re migrating a small number of accounts manually. It’s a two-step process: first export mailbox data from cPanel as MBOX files, then import those files into Microsoft 365.
Step 1: Export Emails from cPanel as MBOX
- Log in to your cPanel account.
- Go to Email Accounts and click on the account you want to migrate.
- Click Check Email to open the webmail client.
- Select Horde and click Open.
- In the webmail interface, right-click on any folder you want to export and select Export.
- Choose Download into an MBOX file >> click OK.
- Save the file locally. It’ll download as a .zip—extract it to get the .mbox file.
Follow the same process to migrate each folder you want (Inbox, Sent, Drafts, etc.).
Step 2: Manually Import MBOX Data into Microsoft 365
- Install Mozilla Thunderbird >> use the ImportExportTools NG add-on to export.
- Cross-check whether all emails, folders, & attachments are accessible.
- Connect your O365 account to MS Outlook via IMAP or Exchange settings.
- Use Outlook or any compatible tool to import the Thunderbird mailbox to PST format.
- Import the PST file into Outlook connected to Microsoft 365, or upload it using Microsoft 365 import services.
- Allow synchronization to complete and verify that all mailbox data appears in Microsoft 365.
Best for: Users who migrate a small number of mailboxes and prefer to use a manual method and have sufficient time to validate the migrated data.
Drawbacks of Manual Methods
- It becomes complicated and slow to export large folders one after another.
- MBOX files not directly compatible with Microsoft 365.
- No bulk export; each account is handled one at a time.
- Risk of data loss if ZIP extraction or export fails midway.
- Attachments may get dropped silently during MBOX conversion.
- No progress tracking or logs were generated during migration.
Method 2: How to Migrate Emails from cPanel to O365 Professionally
