This topic explains how to use the Exchange Management Console or the Exchange Management Shell to configure the transport dumpster feature on a Hub Transport server. The transport dumpster is an optional feature for cluster continuous replication (CCR) and local continuous replication (LCR), and it is enabled by default. The configuration settings for the transport dumpster are applied at the storage group level.

The following functionality is available only on computers running Microsoft Exchange Server 2007 Service Pack 1 (SP1):

For more information about new high availability functionality in Exchange 2007 SP1, see New High Availability Features in Exchange 2007 SP1.

In this procedure, you can change the default configuration settings for the transport dumpster. Here are recommendations for configuring two of the parameters:

If you do not configure the transport dumpster, the default values are used. The default value for the MaxDumpsterSizePerStorageGroup parameter is 18 MB and the default value for the MaxDumpsterTime parameter is 7 days. If either the size limit or time limit is reached, messages are removed from the transport dumpster queue by order of first in, first out.

Setting either value to zero disables the transport dumpster for all CCR and LCR-enabled storage groups in the Exchange organization.

Before You Begin

Verify the following before performing the procedure:

  • Make sure that you have enough space on each Exchange Hub Transport server to accommodate the data in the transport dumpster queue for each storage group.

  • Make sure that the account you use is delegated the Exchange Organization Administrator role. For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.


To use the Exchange Management Console to view and configure the transport dumpster settings

  1. Open the Exchange Management Console from a management workstation that has Exchange 2007 SP1 installed.

  2. Expand Organization Configuration, and then select Hub Transport.

  3. In the result pane, select the Global Settings tab.

  4. Double-click Transport Settings.

  5. In the Transport Dumpster area, type the appropriate values for the Maximum size per storage group (MB) and Maximum retention time (days) fields.

  6. Click OK to save the changes.

To use the Exchange Management Shell to determine the current settings of the transport dumpster

  • Run the following command to view the current settings for the transport dumpster:

    Copy Code
    You should see a listing of the transport dumpster settings for the entire Exchange organization.

To use the Exchange Management Shell to configure the transport dumpster

  • Run the following command:

    Copy Code
    Set-TransportConfig -MaxDumpsterSizePerStorageGroup <size> -MaxDumpsterTime <timespan>

    For example, to configure the maximum size of the transport dumpster per storage group to 30 MB with a transport dumpster life of 7 days, run the following command:

    Copy Code
    Set-TransportConfig -MaxDumpsterSizePerStorageGroup 30MB -MaxDumpsterTime 07.00:00:00
