By default Exchange 2010 allows 2 simultaneous mailbox moves to run. When you perform a migration of many mailboxes you might want to increase this number. Here is how you do it:
1.Open explorer on the Exchange server and navigate to C:\Program Files\Microsoft\Exchange Server\V14\Bin (This is the default path, the path on your server might be different)
2.Make a backup copy of the file MSExchangeMailboxReplication.exe.config. I have a habit of creating a file copy and naming it
3.Use your favorite text editor and open MSExchangeMailboxReplication.exe.config.
4.Find the following part in the file:
5.Change the following parameters to match you requirements:
MaxActiveMovesPerSourceMDB = “5?
MaxActiveMovesPerTargetMDB = “2?
MaxActiveMovesPerSourceServer = “50?
MaxActiveMovesPerTargetServer = “5?
MaxTotalMovesPerMRS = “100?
6.Feel free to look through the rest of the parameters in this file, you will see that there is plenty more parameters you can change.
Please note that changing these values and allowing more simultaneous mailbox moves etc. increases the load on the server. Change these values with care and do not add extremely high numbers.
