Increasing Exchange 2010 local move request limit

Exchange 2010 SP1 reduced the number of users that could be moved at one time within the same database which drastically slowed down our user migration. The limit was originally 5 it is now 2. 

To increase this limit you can edit %programfiles%\Exchange Server\V14\Bin\MSExchangeMailboxReplication.exe.config and change the value for MaxActiveMovesPerTargetMDB to the number you want. Make sure you change it in both locations. I would probably not go over 5. 

Once you do that restart the Microsoft Exchange Mailbox Replication service and your moves should now do more at a time.


  1. In this world, it is too common for people to search for someone to lose themselves in. But I am already lost. I will look for someone to find myself in. See the link below for more info.
