- Add your account. Open BlueMail and tap Add Account, then choose Email.
- Sign in with your t-online.de address. Enter your full t-online.de email address and password.
- Let BlueMail find the settings. BlueMail detects the correct t-online.de servers automatically. If you're asked to enter them manually, use the settings below: incoming secureimap.t-online.de and outgoing securesmtp.t-online.de exactly as listed.
- Done. Your t-online.de inbox appears and stays in sync on every device you sign in on.
First, create a Telekom password for email apps
Telekom requires a dedicated password for email programs. Your Telekom login password won't work in apps, which is the most common reason sign-in fails. Log in at email.t-online.de, open Menü, then Einstellungen, choose Passwörter and set the E-Mail-Passwort für E-Mail-Programme. Use that password in BlueMail with your full t-online.de address.
