I have 1 user not getting emails sent to the dynamic distribution group (DDG) for her OU. Everybody else in that OU gets the emails. I used the Get-Recipient command to show everybody in that DDG, and sure enough she is not showing up.
Info I found online indicates she could be just "mailbox" so I tried to fix the filters. I used this command to "fix" the filters:
Set-DynamicDistributionGroup -Identity [email protected] -RecipientFilter {(RecipientType -eq 'UserMailbox') -or (RecipientType -eq 'MailUser') -or (RecipientType -eq 'MailContact')}
After that I listed the filters for this DDG, and it did update it to include UserMailbox, MailUser and and MailContact. I listed filters for a DDG I have not updated, and other than not having the new settings, the filters look the same (in other words I didn't accidentally remove or change anything).
Fixed the filters nearly 24 hours ago, user still does not show up in the DDG.
What am I missing?
I did substitute the name of my DDG for "[email protected]". I have an old Exchange 2010 on-prem server setup in a hybrid configuration with MS365. The filters in the DDG in the Exchange Management Console have been changed, and they do look right, or they look like they should based on the info I found online.

Hi @Mike P. Smith,
Welcome to the Microsoft Q&A platform!
Based on your description, you have taken the correct steps to update the filter for the dynamic distribution group (DDG). Here are some other things you may want to check:
Set-DynamicDistributionGroup -Identity [email protected] -ForceMembershipRefresh
This can help ensure that the changes take effect.
UserMailbox, MailUser, or MailContact.Get-Recipient command with the **RecipientPreviewFilter**to see if the user appears in the results: Get-Recipient -RecipientPreviewFilter (Get-DynamicDistributionGroup -Identity [email protected]).RecipientFilter
This can help you determine if the user meets the criteria defined by the filter.
Get-Mailbox -Identity [email protected] | Select-Object HiddenFromAddressListsEnabled
If the user is hidden, they will not appear in the DDG.
If you have tried all of these steps and the problem persists, then look in detail at the specific properties and filters.
Please feel free to contact me for any updates. And if this helps, don't forget to mark it as an answer.
Best,
Jake Zhang
Hello Jake,
Thank you for your help!
This just got stranger. When I run the Get-Recipient command, the user doesn't show up at all. Likewise, when I ran the Get-Mailbox command, to make sure the user is not hidden from the address list, I get an error telling me the object '<email address>' could not be found on the domain controller 'SDCN-DC02'.
Now I'm on that domain controller (not our primary, but for whatever reason our on-prem Exchange server (Exchange PowerShell) is using that DC) and her account is there, and looks perfect. She gets emails sent directly to her, she logs in every day.
Actually, I get the same error when I run the command using my email address. I always get emails sent to the dynamic distro in question, so these two issues are unrelated.
I ran a few repadmin commands to look for any replication errors - none found.
Should I force my Exchange server to use the primary DC?
Okay, Get-Mailbox is failing because our mailboxes have been migrated to O365, so that makes sense.
I used the Attribute Editor and changed msexchhidefromaddresslists from <not set> to False. I'll give that some time and try the Get-Recipient command again (even though other users, that are working in the same DDG have this attribute set to <not set>.
