Updating a Dynamic Distribution List

A Dynamic Distribution Group is little bit different from a normal distribution group. The membership of a dynamic distribution group depends on the filters or conditions supplied to it whereas, a normal distribution group membership is calculated by the users added to the particular group. Also, you will not be able to expand a DDL like you can do on a normal distribution group.

This post discusses the steps to modify the filter for a particular DDL to include a new department or role. Once the new filter is applied, all the members matching the filter gets added to the DDL. This has to be done from Exchange Management Shell.

The below fig shows a DDL with the filter details :


You can use the below command to view the currently configured recipient filter :

Get-DynamicDistributionGroup “test” | fl recipientfilter


Now in order to modify the recipient filter, use the following cmdlet:

Get-DynamicDistributionGroup “test” | Set-DynamicDistributionGroup -recipientfilter {}

The modified recipient filter should be mentioned in between the brackets {} as shown above. The change will be applied shortly and if you click the Preview button in the filter tab, you can find the newly added members based on the new filter.
