If you are looking for a way to create an on-premise mail-enabled local security group, you can use the following:
In PowerShell:
New-DistributionGroup -Type Security -Name <UniqueName> [-IgnoreNamingPolicy] [-Alias <Alias>] [-DisplayName "<DisplayName>"] [-Notes "<Description>"] [-OrganizationalUnit <OU>] [-ManagedBy "<owner1>","<owner2>"...] [-Members "<member1>","<member2>"...] [-CopyOwnerToMember] [-MemberJoinRestriction <Closed | ApprovalRequired>] [-RequireSenderAuthenticationEnabled <$true | $false>]Custom actions are not available in the Essentials solution.
In a CoreView custom action:
{
