ProtonMail Bridge Microsoft Outlook 2011 for macOS setup guide

ProtonMail Bridge is an open-source application that allows you to fully integrate your ProtonMail 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 ProtonMail, you must first sign up for a ProtonMail account and download and install the ProtonMail Bridge on your computer.

Once you’ve installed and added your account(s) to ProtonMail Bridge, you will need to configure your email client. ProtonMail Bridge works with most email clients and applications that support IMAP / SMTP connections. In this guide, we provide step-by-step instructions for configuring Outlook 2011 for use with ProtonMail Bridge on your Mac.
