can you assign send permissions to O365 group on DDL ?

[bashrama]

Is it possible to assign send permission to an O365 group on DDL ?

I used PS command option to set permission -AcceptMessagesOnlyFromDLMembers , but it is not working.

If you are trying to configure this on an O365 group, the only available parameter is AcceptMessagesOnlyFromSendersOrMembers. It should still allow you to specify a DDL though
