How to: Throttle your Exchange Server for Mailbox Moves

Follow the following steps to Throttle your Exchange Server for Mailbox Moves

1. Throttle the Receiving Server

2. Throttle the Receiving Database

3. Restrict the number of simultaneous moves

On the MRS Server (see 4. Below):
a) Navigate to <Exchange Installation Path>\Program Files\Microsoft\Exchange Server\V14\Bin.

b) Open the MSExchangeMailboxReplication.exe.config file using a text editor such as Notepad.

c) Navigate to the MRSConfiguration section. You can edit the following properties:

1. MaxActiveMovesPerTargetMDB – This property specifies the total number of tasks MRS can perform that involve the mailbox database as a data target. Types of tasks include moving mailboxes to the database, importing mailbox data into a mailbox located on the database, and restoring mailbox data to a mailbox located on the database. You can specify a value from 0 through 100. The default value is 2 concurrent tasks. Suggestion: leave at 2.

2. MaxActiveMovesPerTargetServer – This property specifies the total number of tasks MRS can perform that involve the server as a data target. You can specify a value from 0 through 1000. The default value is 5 concurrent moves. Suggestion: set to 2.

3. MaxTotalMovesPerMRS – This property specifies the total number of tasks that a single instance of MRS can perform at a time. You can specify a value from 0 through 1000. The default value is 100 concurrent moves. Suggestion: set to 12.

4. Remove the MRSserver CAS from from your Load Balancer pool

5. Set the move request command with the MRS server:

E.g. New-MoveRequest -Identity ‘dame@domain.com’ -TargetDatabase DB01 -MRSServer {server name}
