4. Check your account settings: Verify your outgoing mail server (SMTP) settings. Ensure that the server address, port number, and authentication settings are correctly configured.

5. Disable antivirus or firewall: Temporarily disable any antivirus or firewall software on your computer, as they can sometimes interfere with email sending. If the issue is resolved, adjust your software settings accordingly.
