How to Migrate from Hotmail to Proton Mail: Complete Step-by-Step Guide (2026)

As concerns about online privacy continue to grow, many people are reconsidering the email service they use every day. While Hotmail offers a familiar interface and works well with Microsoft applications, it doesn’t provide the same level of privacy as Proton Mail. Known for its strong encryption and security-first approach, Proton Mail has become a preferred choice for users who want greater control over their personal and professional communications.
If you’re planning to migrate from Hotmail to Proton Mail, it’s important to understand the available options before getting started. In this guide, we’ll compare both email services, explain why users are making the switch, and walk you through the best ways to transfer your emails without losing important data. We’ll also discuss the benefits and limitations of each method so you can choose the one that works best for you.
Why Are Users Switching from Hotmail to Proton Mail?
Hotmail has been a trusted email service for years, especially for users who rely on Microsoft products like Outlook, OneDrive, and Office. However, as online privacy becomes a bigger concern, many users are choosing Proton Mail because it offers stronger security and greater control over personal data.
Unlike traditional email providers, Proton Mail is designed with privacy at its core. It uses advanced encryption technologies to ensure that emails remain accessible only to the sender and the intended recipient. Here are two key security features that make Proton Mail a preferred choice:
Zero-Access Encryption
With zero-access encryption, your mailbox is encrypted in a way that prevents anyone except you from viewing its contents. Even Proton Mail cannot read your emails, contacts, or other stored data because it does not have access to your encryption keys. This ensures that your private information stays completely confidential.
End-to-End Encryption
Proton Mail also protects emails with end-to-end encryption. Before an email leaves the sender’s device, it is encrypted, and it remains unreadable while traveling across the internet. The message is decrypted only after it reaches the recipient’s mailbox, ensuring that no third party can intercept or access the email during transmission.
Things to Check Before Migrating Hotmail to Proton Mail
Before you start transferring your mailbox, it’s a good idea to prepare your Hotmail account. A little preparation can help you avoid migration errors and make the process much smoother.
- Remove unwanted emails, spam, and deleted items to reduce the amount of data being transferred.
- Review your mailbox size and decide which folders or emails actually need to be migrated.
- Organize important emails into separate folders so they are easier to locate after the migration.
- Delete outdated contacts, calendars, or emails that you no longer need to minimize transfer time.
- Make sure IMAP is enabled in your Hotmail account and verify that you can sign in successfully using an email client.
- If required, temporarily disable additional security restrictions or generate an app password to avoid authentication issues during the migration.
Manual Methods to Migrate Hotmail to Proton Mail
If you only need to move a limited number of emails, you can use one of Proton Mail’s built-in migration options.
Method 1: Forward Emails from Hotmail to Proton Mail
You can automatically forward incoming emails from your Hotmail account to Proton Mail by following these steps:
- Sign in to your Hotmail account.
- Open Settings and select View all Outlook settings.
- Navigate to Mail > Forwarding.
- Enable email forwarding.
- Enter your Proton Mail email address.
- Save the changes.
- Open Proton Mail and confirm the forwarding request if prompted.
Method 2: Import Emails Using IMAP
Proton Mail also allows users to import emails directly through IMAP.
- Log in to your Proton Mail account.
- Open Settings and select Import via IMAP.
- Choose Hotmail/Outlook as the source account.
- Enter your Hotmail login credentials.
- Use the following IMAP settings:

- Select the folders you want to import.
- Start the import process and wait until it finishes.
Limitations of Manual Migration Methods
Although manual methods are free and useful for basic migration, they come with several drawbacks, especially when transferring large mailboxes.
- Forwarding only transfers future emails and does not move your existing mailbox.
- IMAP imports emails only and usually does not migrate contacts, calendars, or other mailbox items.
- Large mailboxes can take several hours or even days to complete.
- Email properties such as metadata, folder hierarchy, or read/unread status may not always be preserved.
- Manual methods are not suitable for bulk or enterprise-level migrations.
- The setup process can be confusing for users with limited technical knowledge.
- Authentication issues, network interruptions, or third-party email clients may increase the risk of incomplete migration or data loss.
