Dear Reader, Recently i created a DDG with the following command: New-DynamicDistributionGroup -Name "MAI_APP_TEST" -DisplayName "Mailgroup TEST" -Alias "MAI_APP_TEST" -OrganizationalUnit "<domain>/XXX" -RecipientFilter "MemberOfGroup -eq 'CN=SecurityGroup,OU=XXX,OU=XXX,DC=XXX,DC=XXX'" When i expand the members using the Preview button in the Exchange Management Console, i see usersnames appearing. When i try to send mail, i dont get any error message, not in outlook and not in exchange. I see the following lines in the Exchange message tracker: Timestamp : 21-6-2011 15:02:59 Source : STOREDRIVER EventId : RECEIVE Recipients : {MAI_APP_TEST@<mydomain>} RecipientStatus : {} RecipientCount : 1 RelatedRecipientAddress : Timestamp : 21-6-2011 15:02:59 Source : ROUTING EventId : EXPAND Recipients : {} RecipientStatus : {250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded} RecipientCount : 0 RelatedRecipientAddress : MAI_APP_TEST@<mydomain> Timestamp : 21-6-2011 15:02:59 Source : STOREDRIVER EventId : SUBMIT Recipients : {} RecipientStatus : {} RecipientCount : RelatedRecipientAddress :

Hi, It would be nice also too see the error message you receive when sending a mail to the group. Leif

Hi, It would be nice also too see the error message you receive when sending a mail to the group. Leif I dont receive error messages, that makes this problem hard to troubleshoot.

Nobody..?

Hi ziqz, This is I tested in my lab (Exchange 2007 SP3): Domain: test.com Security Group: workaround Users aa (aa@test.com)and bb(bb@test.com) are member of workaround I use this command to create the DynamicDistributionGroup: New-DynamicDistributionGroup -Name "MAI_APP_TEST" -DisplayName "Mailgroup TEST" -Alias "MAI_APP_TEST" -OrganizationalUnit "test.com/users" -RecipientFilter "MemberOfGroup -eq 'CN=workaround,OU=just a test,OU=test user,DC=test,DC=com'" Then I can see users aa and bb using the preview button in the Exchange Management Console. When I use an internal user send email to Mailgroup TEST, users aa and bb can receive that email. For your issue, I suggest you follow these steps to troubleshoot the problem: 1.send an email to securitygroup, then check whether the users in securitygroup can receive it or not. 2.Create a test group in default OU, then test for the issue.

And how does your Exchange message tracker look like? When it expands members, you see 2? Talking about this line: Timestamp : 21-6-2011 15:02:59 Source : ROUTING EventId : EXPAND Recipients : {} RecipientStatus : {250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded} RecipientCount : 0 RelatedRecipientAddress : MAI_APP_TEST@<mydomain>

Hi ziqz, How about the issue? This is result in my Exchange Message Tracker: Timestamp : 23-6-2011 15:02:59 Source : ROUTING EventId : EXPAND Recipients : aa@test.com, bb@test.com RecipientStatus : {250 2.1.5 RESOLVER.GRP.Expanded; distribution list expanded} RecipientCount : 2 RelatedRecipientAddress : MAI_APP_TEST@test.com Form this result, maybe you need to confrim whether there are users in your DynamicDistributionGroup or not.

Yes, the most difference is that when you expanded distribution list there isn’t any recipients. Maybe you can get help from these: Routing problem with Dynamic Distribution List http://social.technet.microsoft.com/Forums/en-US/exchangesvrtransport/thread/f25c65a4-fd38-4dbe-916d-22e86d93bbe1/ Dynamic Distribution Lists not working as expected (0 recipients during mail routing) https://www.corelan.be/index.php/2008/11/05/dynamic-distribution-lists-not-working-as-expected-0-recipients-during-mail-routing/ Thanks, Evan Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
