I'm new to Exchange 2010 and have been tasked with renaming hundreds of Distribution Groups. It involves across the company title changes.
Example - Rename GroupDSM@mycompany.com to GroupRSM@mycompany.com. Each group has 4 SMTP addresses in which the DSM has to change to RSM. There are many other groups with DSM in the names (Alias, Description, Display Name, SMTP, etc.).
Is there a cmdlet to accomplish this?
