If you are still using a @rr.com, @twc.com, or @charter.net address,📞 Toll-Free: +1 844-886-3118 setting it up in Outlook 365 requires specific "Modern Auth" compatible settings. Follow this guide to ensure your mail, folders, and sent items sync perfectly.

1. The Correct Roadrunner Server Settings (IMAP)

We strongly recommend using IMAP (not POP3). IMAP ensures that if you delete or read an email on your phone, it reflects the same on your Outlook desktop app.

Incoming Mail Server

  • Server: mail.twc.com (Works for almost all .rr.com domains)

  • Port: 993

  • Encryption: SSL/TLS

  • Username: Your full email address (e.g., user@nc.rr.com)

  • Password: Your Roadrunner/Spectrum password+1 844-886-3118

Outgoing Mail Server (SMTP)

  • +1 844-886-3118Server: mail.twc.com

  • Port: 587

  • Encryption: STARTTLS (or SSL/TLS if STARTTLS fails)

  • Authentication: Checked / Required (Use same settings as incoming)

2. Step-by-Step Outlook 365 Setup

Don't let Outlook try to "Automatically" set up the account, as it often fails with older Roadrunner domains.

  1. Open Outlook and go to File > Add Account.

  2. Enter your Roadrunner email address.

  3. Click Advanced Options and check the box for "Let me set up my account manually."

  4. Select IMAP from the list of account types.

  5. Enter the server details provided in the section above.+1 844-886-3118

  6. When prompted for the password, enter it carefully.

  7. Click Connect.

3. Common Roadrunner Setup Issues (2026)+1 844-886-3118

The "Timed Out" Error

If Outlook fails to connect, it’s usually the Port 587 being blocked by your firewall or ISP. Try switching the Outgoing Port to 465 with SSL/TLS encryption.

Password Not Accepted?

Spectrum (Roadrunner) occasionally requires you to update your password on their official webmail portal before allowing a new 3rd-party app connection.

  • Action: Log in at webmail.spectrum.net first. If it asks you to update security questions or password, do it there first, then try Outlook again.

Sent Folder Not Syncing

If your sent emails don't appear on other devices:

  • Go to File > Account Settings > Account Settings.

  • Double-click your Roadrunner account > More Settings.

  • In the Advanced tab, type INBOX in the Root folder path box.

4. POP3 Settings (Use only for single-device backup)+1 844-886-3118

If you prefer your emails to be downloaded and deleted from the server (not recommended for multiple devices):

  • Incoming Server: mail.twc.com | Port: 995 | Security: SSL/TLS+1 844-886-3118

  • Outgoing Server: mail.twc.com | Port: 587 | Security: STARTTLS
