When you modify a public folder or its contents, the database that contains the replica of the public folder that was changed sends a descriptive e-mail message to the other public folder databases that host a replica of the public folder. To reduce traffic on your network, Exchange includes information about multiple changes in one e-mail message. The amount of information that is included in these messages depends on the size limit you set for replication messages. If any message exceeds the specified size limit, that message is sent as a separate replication message.

This topic explains how to use the Exchange Management Console or the Exchange Management Shell to set the size limit for the public folder replication message.

Before you perform the following procedure, you must perform the actions in one of the following sections based on whether you are working with the release to manufacturing (RTM) version of Microsoft Exchange Server 2007 or Exchange 2007 Service Pack 1 (SP1).

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

To perform this procedure in the RTM version of Microsoft Exchange 2007, the account you use must be delegated the following:

  • Exchange Server Administrator role and local Administrators group for the target server

To perform this procedure in Exchange 2007 SP1, the account you use must be delegated the following:

  • Exchange Public Folder Administrator role and local Administrators group for the target server

  1. Start the Exchange Management Console.

  2. In the console tree, expand Server Configuration, and then click Mailbox.

  3. In the work pane, select the public folder database you want.

  4. In the action pane, click Properties.

  5. In <Public Folder Database> Properties, click the Replication tab.

  6. In the Replication message size limit (KB) box, type the message size limit. The value range is from 1 through 2,097,151 kilobytes (KB).

    The default message size is 300 KB.
  7. Click OK to close the <Public Folder Database> Properties dialog box and to save your changes.

  • To set the public folder replication message size limit to 500 KB for the public folder database named PFDatabase that resides on Server01, run the following command.

    Set-PublicFolderDatabase -Identity "Server01\PFDatabase" -ReplicationMessageSize 500
