How to Fix Charter Email Sending Errors in New Outlook
Product
New Outlook
Device & OS
not provided
Scenario
Attempting to send an email using a Charter/Spectrum IMAP account configured in the new Outlook application.
Observed behavior
The application returns a 'You do not have permission to perform this action' error when trying to send outbound emails, even though incoming mail works fine and classic Outlook has no issues.
Before you start

Ensure you have your correct Spectrum or Charter email address and password on hand, and verify that your internet connection is stable before modifying your server configurations.

Solution 1Recommended

Configure Correct Charter IMAP and SMTP Settings

Manually verify and update your outgoing SMTP server settings to ensure New Outlook has the proper authorization to send emails through Spectrum's network.

The new Outlook application sometimes fails to automatically detect the exact security and port settings required for legacy or specific ISP email accounts like Charter/Spectrum. Manually entering the Other IMAP configuration fixes most outbound permission errors.

1
Open account settings

Click the gear icon in the top right corner of New Outlook to open Settings, then navigate to Accounts > Email accounts.

2
Manage your Charter account

Locate your Charter/Spectrum email account in the list and click 'Manage', then select 'Update account' or view the server settings.

3
Verify incoming server settings

Ensure the Incoming server is set to mobile.charter.net, the port is 993, and the security type is set to SSL/TLS.

4
Update outgoing SMTP server settings

Check that the Outgoing server is mobile.charter.net, the port is exactly 587, and security is SSL/TLS. Crucially, ensure 'Password authentication' is enabled and your SMTP username matches your full email address.

5
Save and restart

Save your configuration changes and restart the New Outlook application, then attempt to send a test email.

Configure Correct Charter IMAP and SMTP Settings
Authentication Tip: Make sure you retype your password in the outgoing server configuration if prompted, as missing SMTP credentials are the primary cause of the 'permission' error.

Frequently Asked Questions

Why can I receive emails but not send them in New Outlook with my Charter account?

This usually happens when your incoming IMAP server settings are correct, but your outgoing SMTP server settings are misconfigured, missing a password, or blocked by the New Outlook's security protocols.

What are the correct SMTP outgoing server settings for Charter/Spectrum?

The outgoing server should be set to mobile.charter.net, using port 587, with SSL/TLS security enabled. You must also ensure that outgoing server authentication is turned on and uses your full email address and password.

How do I fix the 'You do not have permission to perform this action' error?

To fix this, go to your email account settings in New Outlook, navigate to the Outgoing (SMTP) settings, and ensure that 'Password authentication' is checked and that your credentials are entered correctly. If it still fails, temporarily disable your antivirus software to check for port blocking.
