I am able to receive emails from a gsuite email id but not able to send back to the gsuite email . can anyone help?

If you are able to receive emails from G Suite but cannot send emails back, there could be several potential causes for this issue. Here are some troubleshooting steps you can consider:

1. Check Email Client Configuration: Ensure that your email client is configured correctly for sending emails. Verify the SMTP server settings, including the port number (usually 587 for TLS) and authentication settings.
2. Firewall or Security Software: Sometimes, firewall or email security software can block outgoing emails. Check if there are any rules or settings that might be preventing emails from being sent to G Suite addresses.
3. IP Address Reputation: If your sending IP address has a poor reputation, it may be blocked by G Suite. You can check your IP's reputation using various online tools. If the IP is new, it may not have established a reputation yet.
4. Email Authentication: Ensure that your SPF, DKIM, and DMARC records are correctly set up. Even if the G Suite team has checked these, it's worth verifying that your domain's records are configured to allow sending emails to G Suite addresses.
5. Check for Bounce Messages: If your emails are bouncing back, check the bounce messages for any specific error codes or messages that can provide insight into why the emails are not being delivered.
6. Contact Your Email Provider: If the issue persists, consider reaching out to your email service provider for further assistance. They may have logs or additional insights into why the emails are not being sent successfully.

By following these steps, you may be able to identify and resolve the issue preventing you from sending emails to G Suite addresses.

Hi @Vikas Gupta 1

Thank you for posting your question in Microsoft Q&A. 

To better assist you, could you please provide additional details for the following question: 

Just to clarify, is the affected account managed via Exchange Online, Exchange On-Premises, or another mail hosting service? If it’s managed through Exchange Online, could you try using the Message Trace feature to verify the mail status after sending, you can refer more via: Message trace in the new EAC in Exchange Online | Microsoft Learn 

Have you received any NDR (Non-Delivery Report) or bounce-back messages after sending the email?

Does this issue occur only with email from GSuite or does it also affect messages with other providers? 

I will be waiting for your response. If you need further assistance, please  let us know.
