Message Delivery Restriction for Dynamic Distribution Lists in Exchange Online

Hi

Is there a way of specifying a list of senders who are allowed to send to a Dynamic Distribution List while we're creating a DDL?

I can see that there's command to perform an update to existing DDL:

Set-DistributionGroup "GROUP-NAME" -AcceptMessagesOnlyFromSendersOrMembers

However, the official MS documentation doesn't discuss any command-line option / parameter to allow setting this-up during the DDL creation--> https://learn.microsoft.com/en-us/powershell/module/exchange/new-dynamicdistributiongroup?view=exchange-ps

Is it only possible after the DDL creation?

Thanks

    Yes, setting delivery restrictions can only be done after the DDL object has been provisioned, and only via the Set-DynamicDistributionGroup cmdlet.
