Hi all, How do I exclude specific email addresses from an existing dynamic distribution group for Exchange 2007 server? Thanks in advance for your help. Best regards

Hi Torx, You need to add the filter to exclude the user in existing RecipientFilter of your Dynamic DG with Set-DynamicDistributionGroup. Lets say you have a DDG for all users with RecipientType = UserMailbox then your RecipientFilter would be like below. -RecipientFilter {((RecipientType -eq 'UserMailbox') -and -not(Name -like 'ExcludeingUserName'))} Reference: Set-DynamicDistributionGroup http://technet.microsoft.com/en-us/library/bb123796.aspx Dynamic Distribution Group Properties > Filter Tab http://technet.microsoft.com/en-us/library/aa997950.aspx

ThanksAmit Tank forpointingme the right direction, but I'm missingsomething as it didn't work. The username is jdoe as in John Doe. This is what's listed on the DDG's recipient filter:((RecipientType -eq 'UserMailbox' -and -not(Name -like 'jdoe')) -and -not(Name -like 'SystemMailbox{*') -and -not(Name -like 'CAS_{*'))

- Give full name in the filter ''John Doe"- Does it show when you view the member of this group?How to View Members of a Dynamic Distribution Grouphttp://technet.microsoft.com/en-us/library/bb232019.aspx- How long did you wait after changing it? It takes upto 2 hours to make it effective since cache information updates every 2 hours.Amit Tank || MVP - Exchange || MCITP - Exchange 2007 || http://ExchangeShare.WordPress.com

Thanks so much Amit! It worked flawlessly.
