Tip: Use Cmdlets to Modify Dynamic Distribution Groups

In the Exchange Management Shell, you can modify the filters and conditions associated with a dynamic distribution group using the Set-DynamicDistribution-Group cmdlet. This cmdlet has several other uses as well. You can use it to:

• Specify a dedicated expansion server to enhance query processing. Set the –ExpansionServer parameter to the identity of the Global Catalog server to use.
• Upgrade dynamic distribution groups created for Exchange 2003 and Exchange 2000 to allow incompatible dynamic distribution groups to be rewritten to work with Exchange Server 2007. Set –ForceUpgrade $true, and then modify any incompatible included recipients or recipient filters as necessary.
