Not receiving mail

Question

Hello Microsoft Outlook Support Team,

I am facing an issue with my domain email account configured on Microsoft Outlook (Microsoft 365).

Issue description:

• I am able to successfully send emails from my domain email address to external email IDs (Gmail, Outlook, etc.).

However, when someone sends an email from a normal email account to my domain email address, they receive an error message stating “address not found”.

As a result, I am not receiving any incoming emails on my domain email account.

Additional details:

The mailbox exists and login to Outlook Web/App is working.

Outgoing emails are functioning normally.

The issue is only with incoming emails.

I request you to please:

Check whether the mailbox is properly provisioned and active on Microsoft 365.

Verify why incoming emails are being rejected with an “address not found” error.

Resolve this issue at the earliest, as it is affecting my business communication.

Thank you for your support.

Best regards,
SS AGRO INDUSTRIES

Hello.

give your user the onmicrosoft.com alias and then email that alias instead. If it works then the issue is 100% mx record issue. Use this document to make sure it’s set up correctly.

To address the issue of not receiving incoming emails on your domain email account configured in Microsoft Outlook, consider the following steps:

1. Verify Domain and MX Records: Ensure that your domain is properly verified in the Microsoft 365 portal and that the MX records are correctly configured to point to the Microsoft 365 mail servers. Incorrect MX records can lead to incoming emails being rejected.
2. Check for Email Forwarding or Rules: Sometimes, rules in Outlook or forwarding settings can divert incoming emails. Make sure there are no rules set that might be causing emails to be redirected or deleted.
3. Check Mailbox Provisioning: Confirm that the mailbox is active and properly provisioned in Microsoft 365. You can check this by logging into the Microsoft 365 admin center.
4. Use Outlook on the Web: Sign in to Outlook on the web to see if emails are being received there. This can help determine if the issue is with the Outlook application on your device.
5. Run Support and Recovery Assistant: Download and run the Microsoft Support and Recovery Assistant, which can help identify and fix issues related to Outlook and Microsoft 365.

If the problem persists after these checks, you may need to reach out to Microsoft support for further assistance.
