Question

b) Perform a DNS server health check
c) Test internal firewall configurations
d) Verify Outlook client settings

Answer 1

To troubleshoot the issue of receiving internal but not external emails, check MX records, perform a DNS server health check, test firewall configurations, and verify Outlook client settings to ensure proper email delivery and reception.

Step-by-step explanation:

If internal email is functioning but no external emails can be received, you should consider conducting several troubleshooting tests. First, check MX records and SMTP relay settings to ensure that your domain's mail exchange records are correctly pointing to your email server and that the server is configured to receive emails from outside the organization.

Secondly, you can perform a DNS server health check to ascertain that your domain name system server is operating correctly, as issues here can prevent external emails from reaching your system. Additionally, testing internal firewall configurations may reveal if incoming emails are being blocked. Lastly, although less likely to impact external emails only, verifying Outlook client settings can confirm if there's a user-side configuration issue preventing the emails from appearing in the inbox.
