    We finally able to solve this issue while working with Office 365 Support. It has taken a long time due to ping pong between on premises and Exchange Online teams. Anyway, after digging a while - solution turned out be an attribute issue, which solved our problem.

     

    1. we re-run the Hybrid configuration wizard then following command was run on affected Dynamic Distribution Group.

     

    Set-DynamicDistributionGroup DDG1@abc.com -RequireSenderAuthenticationEnabled $false

     

    Hopefully, it may help someone out there. Thanks.

Thank you for all 3 previous replies.

First I would request you to check if the https://support.microsoft.com/en-gb/help/3061396/members-of-a-dynamic-distribution-group-in-an-exchange-hybrid-deployme already shared if the filtering properties are working properly.

 

Also, run following commands on EMS

$FTE = Get-DynamicDistributionGroup "Full Time Employees"
Get-Recipient -RecipientPreviewFilter $FTE.RecipientFilter -OrganizationalUnit $FTE.RecipientContainer

to check if it returns the results as expected.

    Ashkb and PeterRising 

     

    Thanks for your replies guys. Well, when i am running below command as per the article.

     

    Set-DynamicDistributionGroup -Identity DDG1@abc.com -IncludedRecipients "MailboxUsers,MailContacts" -RecipientFilter {((RecipientType -eq 'UserMailbox' -or 'MailUser' -or 'MailContact'))}

     

    I am getting this error:

     

    "Cannot bind parameter 'RecipientFilter' to the target. Exception setting "RecipientFilter": "Invalid filter syntax.
    For a description of the filter parameter syntax see the command help.
    "((RecipientType -eq 'UserMailbox' -or 'MailUser' -or 'MailContact'))" at position 39."
    + CategoryInfo : WriteError: (:) [Set-DynamicDistributionGroup], ParameterBindingException
    + FullyQualifiedErrorId : ParameterBindingFailed,Microsoft.Exchange.Management.RecipientTasks.SetDynamicDistributi
    onGroup"

     

    Please suggest the correct Syntax of command. Thanks.

      M. Sheeraz Ansari. 

       

      Try this command instead,

       

      Set-DynamicDistributionGroup -Identity DDG1@abc.com -RecipientFilter {(RecipientType -eq 'UserMailbox') -or (RecipientType -eq 'MailUser') -or (RecipientType -eq 'MailContact')}

        Thanks Peter, your suggested change in command has worked. After applying those changes on Dynamic Distribution Group (DDG), I have waited for around 4 to 6 hours and after applying changes on DDG - I still get same error/ NDR message.

         

        Well, i also observed below Error details in the NDR, please see if it can help.

         


        "Error Details
        Reported error: 550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient DDG1@abc.com not found by SMTP address lookup
        DSN generated by: DX2P273MB0172.AREP273.PROD.OUTLOOK.COM "

         

        Thanks.

      To add more info, yes; this command is returning - correct members of the Dynamic Distribution Group.

       

      $FTE = Get-DynamicDistributionGroup "Full Time Employees"
      Get-Recipient -RecipientPreviewFilter $FTE.RecipientFilter -OrganizationalUnit $FTE.RecipientContainer

       

      Thanks.
