Increasing the amount of concurrent mailbox moves in Exchange 2010

Exchange 2010, by default, allows you to do 2 concurrent mailbox moves.  This is a rather conservative approach, in this age of 10Gb Ethernet and super-fast SAN storage.  Fortunately Microsoft has provided a mechanism whereby we can increase the amount of concurrent moves allowed.

Said mechanism involves editing the MSExchangeMailboReplication.exe.config file, which resides under the C:\Program Files\Microsoft\Exchange Server\V14\Bin\ foler.

These are the changes you need to make if you’d want to allow 20 concurrent moves:

  • MaxActiveMovesPerSourceMDB = “20"
  • MaxActiveMovesPerTargetMDB = “20"
  • MaxActiveMovesPerTargetServer = “20"

Once you’ve made the changes you will also need to restart the Microsoft Exchange Replication service.  Lastly – all the above needs to be done on the target server.

Quick and easy, just the way I like it!
