Learn how to configure your email client for Proton Mail Bridge
Every email client implements the IMAP standard slightly differently. Proton Mail Bridge should work with other email clients, but we can’t guarantee everything will work as expected, and support may be limited.
If you use Bridge with an unsupported client, you may experience crashes or other bugs.
