Explanation:
Box 1: New-DynamicDistributionGroup
Use the New-DynamicDistributionGroup cmdlet to create a dynamic distribution group.
A dynamic distribution group queries Active Directory mail-enabled objects and builds the group membership based on the results. The group membership is recalculated whenever an email message is sent to the group.
Box 2, Box 3: RecipientFilter, RecipientContainer
Example: This example uses the RecipientFilter parameter to create the dynamic distribution group Pacific Northwest in the Users container in the contoso.com domain. The Pacific Northwest dynamic distribution group contains all mailbox users found anywhere in the contoso.com domain who have a State/Province field that equals "Washington" or "Oregon".
New-DynamicDistributionGroup -Name "Pacific Northwest" -Alias "Pacific_Northwest" -OrganizationalUnit
"contoso.com/Users" -RecipientFilter {((RecipientType -eq 'UserMailbox') -and ((StateOrProvince -eq
'Washington' -or StateOrProvince -eq 'Oregon')))} -RecipientContainer "contoso.com" References:
