Hi, I need to move my linked mail boxes to a different domain controller (Exchange 2010 and Windows 2008 R2). Is there any way to do this in bulk? I know how to do this individually. Appreciate your help! Manu

Hi, What do you mean with "change domain controller in a linked mailbox"?Martina Miskovic

Hello Manu, You want to change domain controller for linked mailboxes, or change domain for linked mailbox? If you just want to change domain controller for linked mailboxes, you can follow these steps to do that: Create one csv file that included all the linked mailboxes which you want to change the domain controller. mailbox domain ... ..... Then use this command to set for the linkeddomaincontroller. Import-csv c:\users.csv| foreach{set-mailbox -identity $_.mailbox -linkeddomaincontroller $_.domain} Set-Mailbox http://technet.microsoft.com/en-us/library/bb123981.aspx If you want to change the domain for linked mailbox, you need use script to disconnect mailboxes, then connect to a new domain controller.

Thanks Evan and Martina for your replies. I added a new domain controller to the domain and planning remove the old domain controller. Almost 200 mail boxes are linked to the old DC in the same domain. I can change one by one through EMC. I will try Evan's suggestion and update you. Thanks, Manu
