How to set up o2 Poczta in a mail app

  2. Enter your full o2 Poczta email address and password.
  3. Pick IMAP for incoming mail and enter the server, port and security from the table above.
  4. Enter the SMTP server for outgoing mail (poczta.o2.pl, port 465) and enable authentication with the same login.

o2 Poczta email settings: FAQ

What is the o2 Poczta SMTP server?

The outgoing (SMTP) server of o2 Poczta is poczta.o2.pl, port 465 with SSL/TLS. Log in with your part before the @.

What are the o2 Poczta IMAP settings?

Incoming mail (IMAP): server poczta.o2.pl, port 993, security SSL/TLS, user name: your part before the @.

Should I use IMAP or POP3?

Use IMAP if you read your email on more than one device: messages and folders stay in sync on the server. POP3 downloads messages to one device and is only useful for offline archives on a single computer.

Why does my o2 Poczta login fail in a mail app?

Most providers block plain password logins from mail apps when two-step verification is on. Create an app-specific password in your account's security settings, or use an app that supports OAuth sign-in. Also check that IMAP or POP access is enabled in the webmail settings.
