## **Introduction to Charter Outgoing Mail Server Issues**

The most common reasons include:

* Incorrect SMTP port
* Wrong outgoing mail server
* authentication disabled
SSL not enabled
* Password Recently Changed
* Device with old credentials stored
The connection might be blocked by a firewall or a VPN.
* Spectrum server outage
SmtpException: * Too many emails being sent at once (rate limit)

* Certificate or SSL handshake errors

Signs Your SMTP Server Isn't Working

You may see:
* “Cannot send mail”
* “SMTP server not responding”
* “Authentication failed”
* “Relaying denied”
* Emails stuck in Outbox

* Error Code 0x800CCC0E / 0x80042109

# Charter outgoing mail server not working: Step-by-Step Fixes

Follow these steps in order for best results.

---

## Step 1: Verify Email Password and Account Login

Before you troubleshoot your outgoing email, make sure your Charter/Spectrum password is working.

Log into:

**[https://www.spectrum.net/login](https://www.spectrum.net/login)**
If the login fails, SMTP will NOT work.
How to Reset Spectrum/Charter Email Password

1. Click **Forgot Username or Password**

2. Verify with phone/email

3. Set a strong new password

4. Update password on ALL devices and apps

If *any device* has an old password saved, it can trigger a lockout.

---

## Step 2: Check Your SMTP Settings Carefully

Incorrect SMTP settings are the #1 cause of **Charter outgoing mail server not working.
Correct Charter SMTP Server & Port Settings
Use these EXACT settings:
**Outgoing Mail (SMTP):**
* Server: **smtp.charter.net**
* Port: **587** (recommended)

* Alternate Port: **465

* SSL: **ON

* Authentication: **Required**

* Username: FULL Charter email

* Password: Your email password

If authentication is OFF, email sending will fail immediately.

---
## Step 3: Fix Authentication & SSL Errors
Spectrum requires encrypted connections.

**SSL Requirements for Outgoing Mail

Make sure:

* SSL is enabled

* SMTP authentication is ON
* Username = full email address

* Password matches Spectrum login

On iPhone and iPad:

Settings → Mail → Accounts → Charter Email → Account → SMTP → select the server → make sure **Use SSL** is ON and Port = 587.

On Outlook:

File → Account Settings → More Settings → Outgoing Server → Check:
✔ “My outgoing server requires authentication”

✔ Use same settings as incoming mail

---
## Step 4: Remove and Re-add Your Email Account

Sending will break if old SMTP data is cached.

Outlook Fix
* Remove Charter account

* Restart Outlook

* Re-add using IMAP + correct SMTP
Apple Mail Fix

Delete email account

* Restart Mac

* Add account manually (Other Mail Account)

iPHONE/IPAD FIX

* Settings → Mail → Accounts → Delete Account

* Restart iPhone

* Add manually using “Other”
ANDROID FIX ***
* Clear app cache
* Delete email account

* Re-add with manual setup

This solves 80% of all persistent SMTP errors.
---

## Step 5: Troubleshoot Network Issues Affecting SMTP

Your outgoing server might not work because of your Internet connection.

**Firewalls, VPNs & ISP Restrictions

Temporarily disable the following:

* VPN

* Proxy server

* Firewall rules

Antivirus email scanning

* Public Wi-Fi blocks

Spectrum SMTP ports such as 587 and 465 are normally blocked on public or hotel Wi-Fi.

To test:

Try sending email over mobile hotspot.

If it works → your network is blocking SMTP.

---
## Step 6: Fix Errors in Webmail vs Email Apps
If Webmail works but apps don’t:

* Incorrect SMTP settings

* Send limit exceeded

If Webmail *also* fails to send:

* Your account may be restricted

* The Spectrum server could be down.
