Thanks VasilMichev

 

Sorry for the simple question, but how would I exclude a user called "test" were would i put that filter?

 

Is it done in powershell ? if so what is the actually command?

Yes, in PowerShell, via the Set-DynamicDistributionGroup cmdlet. Get the filter first:

 

Get-DynamicDistributionGroup | fl Name,RecipientFilter

 

Then append the additional inclusion/exclusion criteria as needed. You can ignore anything after the "-and (-not(Name -like 'SystemMailbox{*'))" part, this will be added automatically.

      Just a update - as I believe I have managed to do this using the following command

       

      Set-DynamicDistributionGroup -Identity DISTRIBUTIONLISTNAME -RecipientFilter {((RecipientType -eq 'UserMailbox') -and -not(Name -like 'MAILBOXTOEXCLUDENAME'))}

       

      Just one other question - we a Mail Contact we want to add - do you know the command for adding that in?

        Pn1995 This PowerShell did not work for me

         

        C:\Windows\system32> Get-DynamicDistributionGroup | fl Freedom,RecipientFilter


        RecipientFilter : ((((RecipientType -eq 'UserMailbox') -or (RecipientType -eq 'MailUser'))) -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')))

         

        I inputted the user I want to exclude and it gave an error
