Group Creation Behavior

I ran this:

New-DistributionGroup -Name "Project Aska" -PrimarySmtpAddress Project.Aska@office365itpros.com -DisplayName "Project Aska Team" -Alias Project.Aska Creating a new Remote PowerShell session using Modern Authentication for implicit remoting of "New-DistributionGroup" command ... New! Microsoft 365 Groups are the next generation of distribution lists.
Groups give teams shared tools for collaborating using email, files, a calendar, and more.
You can start right away using the New-UnifiedGroup cmdlet.

Name DisplayName GroupType PrimarySmtpAddress
---- ----------- --------- ------------------
Project Aska Project Aska Team Universal Project.Aska@office365itpros.com

Get-DistributionGroup Project.Aska | ft req*

RequireSenderAuthenticationEnabled
----------------------------------
True

RequireSenderAuthenticationEnabled is True, so external users can't send to this list. I then checked with EAC and found that the incorrect option appears to be selected:

But when I look at PowerShell again, I find that the property is updated. Something screwy is happening here.

Get-DistributionGroup Project.Aska | ft req*

RequireSenderAuthenticationEnabled
----------------------------------
False

  Thank you so much for confirming what I was seeing. I thought for sure I had finally lost it. I have a ticket open with Microsoft support. I will keep you guys up date on my progress with Support.
  
  Thanks,

Hey Vasil,

Thanks for the test. But this is for a standard distro group. not for unified groups/Microsoft 365 groups. Can you check using the regular new-distributiongroup cmdlets?

thanks

  Oh sorry, that's what happens when I reply before getting my daily caffeine dose 🙂
  
  Same behavior though:
  
  [19:25:25][Login script]# New-DistributionGroup sdfghj
  Name DisplayName GroupType PrimarySmtpAddress
  ---- ----------- --------- ------------------
  sdfghj sdfghj Universal sdfghj@michev.onmicrosoft.com
  
  [19:25:31][Login script]# Get-DistributionGroup sdfghj | ft Name,Req*
  
  Name RequireSenderAuthenticationEnabled
  ---- ----------------------------------
  sdfghj True
