Set up O2
in any email app.
The correct IMAP, POP3 and SMTP settings for O2. Use these with BlueMail, Outlook, Apple Mail, Thunderbird or any other mail client.
Instead of using O2's webmail interface, you can use a mobile or desktop email app like BlueMail, Outlook, Apple Mail or Mozilla Thunderbird. Desktop email apps offer more features, faster access and offline reading. Your messages are right there even without a connection.
How to set up O2 in BlueMail
- Get BlueMail. Install BlueMail free on iOS, Android, Mac, Windows or Linux, or open web.bluemail.me in your browser.
- Add your account. Open BlueMail and tap Add Account, then choose Email.
- Sign in with your O2 address. Enter your full O2 email address and password.
- Let BlueMail find the settings. BlueMail detects the correct O2 servers automatically. If you're asked to enter them manually, use the settings below: incoming mail.o2.co.uk and outgoing smtp.o2.co.uk exactly as listed.
- Done. Your O2 inbox appears and stays in sync on every device you sign in on.
O2 email no longer exists
O2 UK closed its consumer email service years ago. The last o2.co.uk mailboxes were deleted in 2016 and mail sent to those addresses bounces, so no app or webmail can sign in to an o2.co.uk address today. If you're setting up a different address, BlueMail will detect its settings automatically.
