[08:52:51][Login script]# Get-DistributionGroup sdfghj | ft Name,Req*
Name RequireSenderAuthenticationEnabled

sdfghj False
And I see absolutely no trace of this in the event log. Check the admin audit log in Exchange/Unified Audit log on your end?- Robert BollingerApr 22, 2021Brass Contributor
Here are my admin audit logs: showing settings. no changes made after group created. I also checked the unified audit logs and only see one instance of new-distributiongroup and no other mentions of *distributionGroup*
Thought not shown here, if you use the option RequireSenderAuthenticationEnabled $True its ignored and the group is still allowed to accept messages from all senders.
However this only occurs in my companies test and prod tenants, it does not in my tenant.
