How to Set Up "ProtonMail" with Third-Party Apps via Bridge
To use ProtonMail with third-party applications like Outlook, Thunderbird, or Regzion tools, ProtonMail Bridge is required. It acts as a local email gateway that securely translates your encrypted mailbox into IMAP/SMTP access.
Stage 1: Download and Install ProtonMail Bridge
1 ) Visit proton.me/mail/bridge and download the correct version for your OS (Windows, macOS, Linux).
2 ) Install the application following the installer prompts.
3 ) Launch ProtonMail Bridge and log in using your ProtonMail credentials.
Stage 2: Configure ProtonMail Bridge
1 ) Setup up ProtonMail Account in the Bridge interface.
2 ) Once added, click on the account to view local IMAP/SMTP credentials (usually 127.0.0.1 with unique ports).
Stage 3: Connect ProtonMail to Regzion Software
1 ) Open Regzion Software and visit to screen of Email Account Settings or Migration/Backup Configuration.
2 ) Open your ProtonMail Bridge app and select the account. Copy the following details:
- IMAP Server: 127.0.0.1
- IMAP Port: e.g., 1143 (check your Bridge app)
- SMTP Server: 127.0.0.1
- SMTP Port: e.g., 1025 (check your Bridge app)
- Username: Shown in Bridge (usually your email)
- Password: Copy the Bridge-generated password
3 ) In Regzion software, paste these credentials into the appropriate fields for IMAP and SMTP.
4 ) Test the connection. If the test passes, you are now ready to perfom migration and back up operations with ProtonMail account.
Note: ProtonMail Bridge must remain running in the background while Regzion accesses the account.
