Hi DONNA,

Thank you for reaching out. Based on what you shared, the symptoms are not identical to the OP issue. In your case, even a self-sent test email failed, and this may indicate a broader mailbox or synchronization problem.

Please check if the missing emails appear in the web version of Outlook, confirm that your mailbox and cloud storage are not full, and try sending an email from an external account. If you are using a business account, please contact your school or company's Microsoft 365 administrator and ask them to check the Microsoft 365 service health status. You can also ask the administrator to perform a message trace to help identify the issue.

If you are unsure who your IT administrator is, you can refer to this official Microsoft guide for assistance: How do I find my Microsoft 365 admin? - Microsoft Support.

Answer 1

Since the self-sent test email was delivered successfully, the mailbox can still receive at least some mail. The next checks are the Outlook.com mailbox-side settings and message placement checks:

In Outlook on the web, check the Other tab if Focused Inbox is enabled. Messages can be delivered there instead of Inbox.
Check Filter > Sort > Date to make sure messages are not just appearing out of order.
Check Junk Email settings and the Junk Email folder again. If a message is there by mistake, mark it as not junk.
Check whether email forwarding is enabled.
Check again that there are no email rules affecting delivery or moving messages.
Check mailbox and Microsoft cloud storage. If storage is full, Outlook.com cannot send or receive email, and messages sent while storage was full are bounced back and are unrecoverable.
Ask one of the affected senders whether they received a non-delivery report. If they did, the error details can help identify why the message was not accepted.

If those checks do not find the missing mail, use Outlook.com support from within the web app:

Sign in to Outlook.com.
Select the Help icon in the upper-right corner.
Search for cannot receive emails.
Scroll to Still need help? and select Yes.
Choose Chat with a support agent in your web browser.
Provide the date the issue started and examples of affected senders.

Hi Kanto,

Since a self-sent message was delivered, your mailbox is still active, but messages from external senders may be blocked, rejected, redirected, or not synchronized with the current Outlook client.

For the best assistance in this case, please ask your son whether he received a bounce-back or non-delivery report, and share with me the full wording of the error message if one exists. This will help determine whether this is an Outlook synchronization issue or a mailbox delivery issue.

Thank you for your cooperation and understanding. Hope to hear from you soon.
