My Outlook.com doesn't receive NDR (non delivery report)

Hi,

 

I have a personal email on outlook.com (with Microsoft 365 Familly).

I always use the web client from https://outlook.live.com.

 

If I send an Email to a non existant address, I never receive any NDR.

I have check my spam folder, there is nothing.

I have no rules, no Email transfert, no IMAP configuration, no POP configuration, ...

 

That seems useless, but some time I wait some answer from people, and I discover after weeks that I have made a small error in their Email.

I already miss important business because off that. And I can't call my client each time I send an Email to be sure they get it.

 

How can I receive the NDR ?

 

Thanks for your help.

      Hi,

      It seems to have no restriction in https://account.microsoft.com/security.

      I have no Email rules and I receive nothing in the Junk EMail.

       

      "You may check by using a 'known' invalid address to see whether it goes"

      => That's what I do, and the Email goes nowhere, and there is no error, that's the whole problem.

      Thanks,
