Multiple Ways to Import MBOX Files into ProtonMail

Moving MBOX files into a web-based email service like ProtonMail can seem challenging, especially for users who aren’t tech-savvy. Fortunately, MacArmy is here to simplify the process by offering multiple methods to help you import MBOX files into your ProtonMail account. Read on to explore the different ways to complete this transfer smoothly.
Understanding MBOX and ProtonMail – A Quick Overview
MBOX is a widely-used file format designed to store collections of email messages in one place. It is supported by several desktop email clients like Apple Mail, Eudora, Thunderbird, and even some cloud-based platforms like Gmail. Since MBOX stores data in a plain-text structure, it’s versatile and can be accessed on various systems without much hassle.
In contrast, ProtonMail is a secure, web-based email platform known for its strong focus on privacy. It offers features like end-to-end encryption, a zero-access framework, and a robust commitment to data protection. These qualities make ProtonMail an excellent choice for managing sensitive communications, and a trusted destination for storing email archives like those in MBOX format.
In the next section, we’ll explore why users choose to move their MBOX files into ProtonMail, followed by the best methods to get it done.

How to Import MBOX to ProtonMail? – Discover Multiple Methods
There are several ways to move MBOX files into a ProtonMail account, depending on your needs and technical comfort level. Below are the most effective methods you can use:
- Via the ProtonMail Import-Export App
- Through ProtonMail Bridge
- With the Help of Thunderbird
- Using a Direct Automated Solution
Let’s break down each method step-by-step in the following sections so you can choose the one that fits you best.
Method 1: Import MBOX to ProtonMail Using the Import-Export App
If you’re using a ProtonMail paid plan, you get access to two official tools for importing MBOX files: the Import-Export App and ProtonMail Bridge. Let’s begin with the Import-Export App method:
Steps to Use the Import-Export App:
- Download & Install the Import-Export App from the official ProtonMail website.
- Launch the application and sign in with your ProtonMail credentials.
- Click the “Import” button in the interface.
- Browse and select the MBOX files saved on your computer.
- Choose the target folder in your ProtonMail account where you want the emails to be stored.
- Click “Start Import” to begin transferring your MBOX emails.
This process will upload your selected MBOX emails directly into ProtonMail, maintaining folder structure and message integrity.
Method 2: Move MBOX to ProtonMail Using ProtonMail Bridge
This method uses Thunderbird along with ProtonMail Bridge and is ideal when you need to import multiple MBOX files into ProtonMail at once.
Steps to Transfer MBOX to ProtonMail via Bridge:
- Import MBOX Files into Thunderbird using the ImportExportTools NG add-on.
- Download and install ProtonMail Bridge from ProtonMail’s official site.
- If you’re working with large MBOX files, it’s recommended to increase Thunderbird’s timeout settings:
- Go to Thunderbird Settings > General > Config Editor…
- Search for mailnews.tcptimeout
- Increase the value (e.g., set it to 1000) to allow more time for large file transfers.
- Locate the folder in Thunderbird that contains the imported MBOX emails.
- Select all emails, right-click, and choose Copy To.
- Then, select your ProtonMail account and the target folder where you want to store the emails.
Note: Both the Import-Export App and ProtonMail Bridge are only available with ProtonMail’s paid plans. If you’re using a free account, continue to the next method below.
Method 3: Import MBOX Files into ProtonMail Using Thunderbird (For Free Account Users)
This approach is best suited for those using a free ProtonMail account, as it doesn’t rely on the paid tools. You’ll need to configure ProtonMail in Mozilla Thunderbird and then move your MBOX emails manually.
Steps to Import MBOX to ProtonMail via Thunderbird:
- Open Thunderbird and go to Account Settings.
- Click on Account Actions and choose Add Mail Account.
- Enter your ProtonMail credentials including name, email address, and password.
- Select IMAP as the account type and complete the configuration.
- Once your ProtonMail account is added, right-click the account in the sidebar.
- Use the ImportExportTools NG extension to load your MBOX files:
- You can choose to import files one at a time or import multiple files using a directory.
- After the MBOX files are loaded into Thunderbird, manually drag or copy the emails into your ProtonMail folders.
Note: This method is entirely manual and requires time, especially when dealing with large MBOX files. However, it works well for free users without access to ProtonMail’s paid features.
Limitations of the Manual Methods
While manual approaches are accessible, especially for users with free ProtonMail accounts, they come with several challenges:
- Some users may face authentication or connection issues while setting up ProtonMail Bridge.
- If your MBOX file contains damaged headers or formatting errors, it can lead to failed imports or even data loss.
- Importing large MBOX files manually can be time-consuming and may disrupt the folder structure within your ProtonMail account.
- Manual steps involve multiple tools and configurations, which may be difficult for beginners or non-technical users to follow.
- The process depends entirely on Thunderbird, meaning additional installation and setup is necessary before you can begin.

The most straightforward method to import MBOX files into ProtonMail is by using the MacArmy Mac MBOX Converter Tool. This reliable application enables users to transfer both individual and multiple MBOX files to ProtonMail in a single operation. It’s designed to be user-friendly, secure, and highly efficient.
