Just tested in my tenant, PowerShell still uses a default value of True (external senders disabled) unless you specifically set it to False.

[09:39:05][Login script]# New-UnifiedGroup newwwwww -DisplayName newwwwww

Name DisplayName GroupType PrimarySmtpAddress
---- ----------- --------- ------------------
newwwwww_5c60ee20-e3a7-40b6-b50f-95be93ceb0e7 newwwwww Universal newwwwww@michev.info

[09:39:40][Login script]# Get-UnifiedGroup | ft Name,Require*

Name RequireSenderAuthenticationEnabled
---- ----------------------------------
newwwwww_5c60ee20-e3a7-40b6-b50f-95be93ceb0e7 True

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

  That's so strange when I do it, I get the same results as you but then if I check "accept messages from" its set to senders inside and outside.
  
  Its almost like it changes the settings on its own.
