Installation on macOS

Proton Mail Bridge is an open-source application that allows you to fully integrate your Proton Mail account with any program that supports IMAP and SMTP. This includes Microsoft Outlook, Mozilla Thunderbird, and Apple Mail.

It runs in the background on your computer and seamlessly encrypts and decrypts your mail as it enters and leaves your computer.

Before you configure Outlook to use Proton Mail, you must first sign up for a paid Proton Mail plan and download and install Proton Mail Bridge on your computer.

Once you’ve installed and added your account(s) to Proton Mail Bridge, you’ll need to configure your email client. Proton Mail Bridge works with most email clients and applications that support IMAP/SMTP connections.

In this guide, we provide step-by-step instructions to configure the new Outlook app to use Proton Mail Bridge on your Mac. If you have an older version of Outlook installed, take a look at our instructions for Outlook 2019, Outlook 2016, or Outlook 2011.
