Few days ago, I created an Office 365 group. I can't receive any e-mails on that group's e-mail address. When I send something from my private e-mail I get response from postmaster@airly.eu which says that my message can't be delivered. The group is visible under groups tab in the Admin center. I tried to recreate the group, however, I couldn't even delete the group. It reappears after deletion. I waited more than 24 hours. Nothing. I'd like to ask for help here. I created a ticket but got no response. I tried to call support but that was without success either. I waited 12 minutes on the line just to hear a greetings from the second consultant that I was redirected to and then got disconnected.

Thank you for your answers. The problem has been solved with help from Microsoft Support.For anyone experiencing the same, execute these commands in Windows Azure Active Directory:Set-ExecutionPolicy Unrestricted -Force $User = Get-Credential Connect-MsolService -Credential $User Get-MsolGroup Remove-MsolGroup -ObjectID d7e7f7g7-a6a6-4444-b9c9-h1g2f3e4d5c6Where d7e7f7g7-a6a6-4444-b9c9-h1g2f3e4d5c6 is just an example of ObjectID of the bugged group shown on the list from the previous command.

I can't receive any e-mails on Office 365 group's e-mail address and can't even delete the group

I assume that email is accepted for other recipients in the tenant?

If so, can you check the email addresses assigned to the group and make sure that you are using the right one. It's easy to make a mistake:

[PS] C:\> Get-UnifiedGroup -Id GroupAlias | Format-List EmailAddresses

When you are sure that you are using the right address (any of those listed should work), you can post the NDR here and we will look at it to see if any clues exist.

No e-mails are delivered to any of the users assigned to the group.
I re-checked group id on Admin center. It matches the one I'm trying to send an e-mail.
I'd like to add that other groups are working fine.

The NDR:

The error says that Azure Active Directory cannot find any recipient with that email address (contact@airly.eu) in your tenant. That's why I asked you to run the PowerShell command to verify what email addresses are assigned to the group. There's no doubt that the address is invalid... so given that email is working properly for other recipients in the tenant, it's likely that you are using an incorrect address for the group. We need to go back to basics and find what address is assigned and test using that...
