Modern Dynamic Distribution Groups in Exchange Online

Andres Bohren

Hi All,

Did you hear about the “Modern Dynamic Distribution Groups in Exchange Online”? Little less dynamic but with more caching 😊

Create a new Dynamic Distribution Group in Exchange Online

New-DynamicDistributionGroup -Name DDG-Icewolf-UserMailbox -IncludedRecipients MailboxUsers -ConditionalCompany "Icewolf"

Show the Details - note the Recipient Filter

Get-DynamicDistributionGroup -Identity DDG-Icewolf-UserMailbox | fl

If you check for the Members - it’s still empty

Get-DynamicDistributionGroupMember -Identity DDG-Icewolf-UserMailbox

You chan check for the Member with the Recipient filter

Get-Recipient -RecipientPreviewFilter "((((Company -eq 'Icewolf') -and (RecipientType -eq 'UserMailbox'))) -and (-not(Name -like'SystemMailbox{\*')) -and (-not(Name -like 'CAS\_{\*')) -and (-not(RecipientTypeDetailsValue -eq 'MailboxPlan')) -and (-not(RecipientTypeDetailsValue -eq 'DiscoveryMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'PublicFolderMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'ArbitrationMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'AuditLogMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'AuxAuditLogMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'SupervisoryReviewPolicyMailbox')) -and (-not(RecipientTypeDetailsValue -eq 'GuestMailUser')))"

After some time, the Members of the Dynamic Distribution Group show up

Get-DynamicDistributionGroupMember -Identity DDG-Icewolf-UserMailbox

No changes in Outlook. The Members of a “normal” Distribution Group can be viewed.

Not in the case of a dynamic distribution group.
