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 email@example.com 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.

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 error says that Azure Active Directory cannot find any recipient with that email address (email@example.com) 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...

Sorry for the misunderstanding. I'm new to Microsoft's eco-system.
Here's the result of the command you provided:

If I try to create the group:

I'm assigned to 'contact' group in Admin center but I can't see that group in OWA:
I'm assigned to 'apirequest' group as well which works OK.
Here's a screenshot from Admin center:
Here you can see bugged 'contact' group.
And here is 'apirequest' group which works fine:

OK, and you're testing with a Gmail account - which means that the group properties have to allow it to accept email from another domain. I can't send email to firstname.lastname@example.org either because your tenant won't accept the message.You should check the value of the group's RequireSenderAuthenticationEnabled property. If it is True, it means that only authenticated senders can send messages to the group. If False, anyone from any domain (including Gmail) can. It could be as simple as that...
Get-UnifiedGroup -Id Contact | Fl RequireSenderAuthenticationEnabled
Sep 06 2017 05:04 AM
Sometimes it takes a little while for OWA to display a new group. Because you can see it in Office 365 Admin, the group does exist in the directory, so that's fine.

Result of the provided command:
PS C:\Windows\system32> Get-UnifiedGroup -Id Contact | Fl RequireSenderAuthenticationEnabled The operation couldn't be performed because object 'Contact' couldn't be found on 'DB6P195A002DC03.EURP195A002.PROD.OUT LOOK.COM'. + CategoryInfo : NotSpecified: (:) [Get-UnifiedGroup], ManagementObjectNotFoundException + FullyQualifiedErrorId : [Server=HE1P195MB0123,RequestId=38412ee6-7254-4781-9894-9b645839ed5e,TimeStamp=2017-09-0 6 12:05:18] [FailureCategory=Cmdlet-ManagementObjectNotFoundException] 1050376C,Microsoft.Exchange.Management.Reci pientTasks.GetUnifiedGroup + PSComputerName : outlook.office365.com
I tried with lowercase 'contact' either. The same error.
'contact' group settings in Admin center:
And please bear in mind that I'm not able to delete the group (it reappears) as well as receive any e-mails. I'm trying to resolve the problem since Monday or before, so it's not something that would resolve itself over time.
Microsoft Support just called me, they were sorry that it took so long, we were talking about the problem and I'm waiting now for some commands that I should execute in PowerShell since they had similar problem few weeks ago.

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-h1g2f3e4d5c6
Where d7e7f7g7-a6a6-4444-b9c9-h1g2f3e4d5c6 is just an example of ObjectID of the bugged group shown on the list from the previous command.
Sep 06 2017 07:27 AM
It's good that the problem is resolved, but it would be better if you understood why the problem occurred in the first place. Did Microsoft support figure things out or did they fix the issue by simply blowing away the group object in Azure Active Directory? Although effective, it seems an odd approach to me - kind of like using the famous ADSIEdit utility to remove the object for Exchange servers you no longer want by performing "brain surgery" on Active Directory...

I am wondering if this command is for deleting the group?
