Cannot receive email Office 365

All of a sudden a client of mine doesn't receive email.  He is a single Office 365 user.  Invoices are current, etc.

He can send email from both the portal and Outlook... doesn't receive email at either location.

The only email that he can receive is email he sends to himself.

Did you check his MX record? Any NDRs or any other type of error messages? What does a message trace show? https://docs.microsoft.com/en-us/exchange/monitoring/trace-an-email-message/run-a-message-trace-and-view-results

You can also test by sending message to the user@domain.onmicrosoft.com alias, does this work?
