Overview

ProntonMail is a privacy-first email service that is mainly used by users who prioritize security and data protection. Whereas Outlook is a well-recognized email service among people, its user-friendly, easy-to-use, integrated email management capabilities make it more suitable for users. However, ProtonMail is an end-to-end encrypted email service and does not support standard services like IMAP/SMTP. Thus, moving emails from ProtonMail to Outlook will not be as simple as entering the credentials. Users need to follow the steps properly to ensure that ProtonMail emails to Outlook are transferred smoothly and correctly.

Reasons to Forward ProtonMail to Outlook

  • Manage Multiple Email Accounts Together: Since Outlook is a multi-client platform, adding your emails helps you easily access them with other accounts like Gmail and Roundcube. On the other hand, ProtonMail doesn’t offer any facility to add non-ProtonMail accounts, once again highlighting Outlook’s prominence as the preferred multi-email client.
  • Enhanced Productivity Features: Outlook has access to Microsoft 365 applications like Teams, OneNote, and Yammer which help people collaborate on projects professionally. There are no such applications for ProtonMail users, signaling a gap in productivity features between these two email clients.
  • Comfortable Account Storage: Outlook has 15 GB of email storage, expandable up to 1.5 TB with the Microsoft 365 auto-archiving policy. On the contrary, ProtonMail’s email storage is limited to 1 GB for free accounts, extending to 15 and 100 GB for the premium plans. This limitation in email storage justifies the urgency to add ProtonMail to Outlook.

Requirements to Import ProtonMail Emails to Outlook

We will discuss the requirements for setting up a data transfer process without problems. For ProtonMail Premium subscribers, the following should be completed beforehand:

ProtonMail Bridge: It is an app to link ProtonMail accounts with external email clients like Outlook or Thunderbird by shifting the IMAP configuration.

  • The bridge creates a secure connection between the account and the email client via a TLS connection. Users must have access to their Single Remote Password for this method to work.
  • Once installed and set, users don’t need to operate it themselves as it is designed to work in the background, utilizing only minimal resources of the machine.

In case you don’t have access to the premium version, you need to do the following:

ProtonMail Import-Export: This is an application for getting a copy of the email data on the local machine. Install this app on your computer.

Manual Methods to Add ProtonMail Emails to Outlook

There are a few manual ways to transfer ProtonMail emails to Outlook. Let us move forward to explore the methods.

Method 1: Set Up Forwarding to Add ProtonMail to Outlook

You can forward ProtonMail emails to Outlook manually by following the following steps:

  1. Access ProtonMail Settings and enable Email Forwarding.
  2. Open the Outlook app >> File option >> Add Account.
  3. Type ProtonMail email ID, select the manual setup, and click Connect.
  4. Provide IMAP server details and click Next.
  5. To complete the setup, type the account password and hit Connect.
Note: This method requires ProtonMail Bridge setup, and it is available only for premium (Mail Plus and Proton Unlimited) users.

Method 2: Import-Export App to Migrate ProtonMail Emails to Outlook

Users then have to convert the files into Outlook-acceptable format, and only then can they import ProtonMail emails to Outlook.

The steps for the application are as follows:

  1. Open the ProtonMail Import Export App and select the ‘Add Account’ option.
    Launch Proton Import Export
  2. Afterward, log in using your Proton Mail credentials and click the ‘Next’ button.
    Enter Credentials
  3. When the STATUS indicates ‘connected,’ proceed by selecting the ‘Export All’ option.
    Export All
  4. Now, continue by clicking the ‘Export’ button.

  5. Choose the folders, apply a date filter, and opt for the MBOX format. Designate a location to save the email data and click the ‘Export’ button.
    Configure Settings
  6. After the export process concludes, click the ‘Okay’ button.
    Click Okay
  7. You can now access and confirm your MBOX files at the location you designated.
    Locate MBOX

Note: The task is not done yet; as explained previously, Outlook can’t use MBOX files directly. So you need to import MBOX file to Outlook before using it.

Drawbacks of the Manual Method

While using the manual methods, configurations are possible, but they often come with significant limitations:

  • Not for all users: ProtonMail Bridge is not for Free Accounts. Only users who have a ProtonMail subscription can access the Bridge.
  • Technical Experience: Manual solutions require technical knowledge and can be a complex task for beginners or for users who do not have any technical knowledge.
  • No Full Sync: Maybe a portion of the email data is exported, such as the inbox or selected single emails only.
  • No Batch export: The manual technique allows users to drag & drop each email. This can not be a useful solution for those who want to migrate data in bulk.
  • Risk of Data Loss: In some cases, during the process, there is a risk of data loss of email items, such as attachments or metadata.
  • Time-Consuming: Using the manual method, the user requires various apps and wants to repeat the steps, which can be time-consuming.
