How to RoadRunner Email Not Working? Fixes and Settings
Written by Justin Cener, Technical Executive and Staff Writer at Corbett Software. Justin covers email data formats and migration workflows.
RoadRunner email suddenly not working? The most common reason is not a fault at all, it is that RoadRunner is now Spectrum, and the old login and server settings no longer fit. Get those right and it usually works again straight away. Here is what changed and how to fix it.
Summary: RoadRunner email is now run by Spectrum. Your @roadrunner.com or @rr.com address still works, but you sign in at Spectrum and your email app needs Spectrum’s current server settings, which use the charter.net domain. Most RoadRunner not working problems come down to the wrong settings, an old login or a password that needs resetting. The correct settings and steps are below.
First, RoadRunner Is Now Spectrum
Before troubleshooting, one fact explains most of these problems. RoadRunner was Time Warner Cable’s email service. Charter Communications bought Time Warner Cable and folded RoadRunner into Spectrum. The RoadRunner brand is gone, but the email addresses live on.
That means your old @roadrunner.com, @rr.com, @twc.com or @charter.net address still sends and receives mail. What changed is where you sign in and the settings your email app needs. You now log in at Spectrum’s webmail rather than any RoadRunner site, and email apps need Spectrum’s current server settings. Once you know that, most not working issues are quick to fix.
Why Your RoadRunner Email Stopped Working
A short list of causes covers nearly every case. Knowing which one you have tells you which fix to try.
- Wrong server settings. The most common cause. Apps set up years ago use outdated servers, or people enter spectrum.net when the servers actually use the charter.net domain.
- Signing in at the wrong place. There is no RoadRunner login any more. You sign in through Spectrum.
- A password that needs resetting after a security update, which then has to be updated in every email app.
- A Spectrum server outage, which is out of your hands and just needs time.
- A deactivated account. Spectrum has been closing some long unused legacy accounts.
Fix It in This Order
Work from the quickest and most likely fix down. This order clears most cases before the later steps.
RoadRunner Email Not Working: Fix Order
Work top to bottom. Most cases are the first two.
Sign in at Spectrum webmail. Confirm the account works at webmail.spectrum.net before touching the app.
Fix the server settings. Use Spectrum’s charter.net servers, IMAP 993 and SMTP 587. See the table below.
Reset the password. Reset it on the Spectrum site, then update it in every email app.
Remove and re-add the account. A clean re-add clears lingering config errors on a phone.
The Correct RoadRunner Server Settings
This is the fix that solves most cases, so it is worth getting exact. If your email app cannot send or receive, wrong server settings are almost always why. Enter these in your app’s account settings. Note the servers use the charter.net domain, not spectrum.net, which is the detail that catches most people out.
| Setting | Incoming (IMAP) | Outgoing (SMTP) |
|---|---|---|
| Server | mobile.charter.net | mobile.charter.net |
| Port | 993 | 587 |
| Security | SSL or TLS on | SSL or TLS on |
| Authentication | Required | Required |
| Username | Your full email address | Your full email address |
Set the outgoing server to require authentication and to use the same sign in as incoming. If your address is on an older regional domain, Spectrum’s webmail settings page lists the exact server for it, but the ports and security above stay the same.
Reset Your Password the Current Way
If the problem is a sign in failure, reset the password through Spectrum, not any old RoadRunner page.
- Go to Spectrum.net and choose the sign in option, then Forgot password.
- Enter your email address or username and verify your identity as prompted.
- Set a new strong password.
- Update that new password everywhere the account is set up, on your phone, your computer and any mail app, or they will keep failing to connect.
Fix Sending and Sync on Your Phone
If webmail works but your phone will not send or update, the account on the device needs refreshing.
- Check the server settings on the phone against the table above, paying attention to the outgoing server and port 587.
- Make sure the outgoing server has authentication switched on, since mail stuck in the outbox is nearly always this.
- If it still fails, delete the account from the phone, which only removes it from the device and not from the server, then add it back with the correct settings.
- Confirm sync is turned on for the account so new mail comes through.
Keep Your RoadRunner Emails Safe
There is one precaution worth taking once your email is working again. RoadRunner accounts are tied to a Spectrum subscription, and Spectrum has been closing some long unused legacy accounts. If your account ever lapses, or you cancel the service, you can lose access to years of mail. Keeping a local copy, or moving the mailbox to an account you fully control, protects against that. The Corbett IMAP Migration Tool connects to your RoadRunner account over IMAP and copies the mailbox to another provider such as Gmail or Outlook, or saves it to your PC, with the folder structure kept. It previews the mail first, filters by date or sender, and a free demo edition lets you try it. It runs on all editions of Windows.
People Also Ask
Q1: Why is my RoadRunner email not working?
A1: Most often because RoadRunner is now Spectrum and your app has outdated server settings, or you are trying an old RoadRunner login. Sign in at Spectrum webmail to confirm the account works, then update your app to Spectrum’s current settings.
Q2: Is RoadRunner email still active in 2026?
A2: Yes, existing addresses still work through Spectrum, though Spectrum has closed some long unused accounts. You cannot create a new RoadRunner address, but @roadrunner.com and @rr.com addresses continue to send and receive.
Q3: What are the correct RoadRunner email server settings?
A3: Use Spectrum’s servers on the charter.net domain, with IMAP on port 993 and SMTP on port 587, both with SSL or TLS on and authentication required. Enter your full email address as the username.
Q4: How do I reset my RoadRunner email password?
A4: Reset it through the Spectrum website, not an old RoadRunner page. Choose Forgot password, verify your identity, set a new one, then update that password in every app where the account is set up.
Q5: Why can I receive but not send RoadRunner email?
A5: That is an outgoing server problem. Check that SMTP is set to port 587 with authentication turned on and SSL or TLS enabled. Mail stuck in the outbox is nearly always the outgoing authentication setting.
Conclusion
RoadRunner email not working almost always traces back to one thing, it is Spectrum now, so the old login and settings no longer fit. Sign in at Spectrum webmail to confirm the account, then set your app to Spectrum’s current servers on the charter.net domain with IMAP 993 and SMTP 587. Reset the password through Spectrum if sign in fails, and re-add the account on your phone if sending still will not work. Since these addresses depend on a Spectrum subscription, keeping a backup of your mail is a sensible safeguard. What is your RoadRunner email doing, failing to send, or not letting you sign in at all?
