Configure the Pickup Directory and the Replay Directory

 

Applies to: Exchange Server 2013

Topic Last Modified: 2014-03-04

The Pickup and replay directories are used by the Transport service on Mailbox servers and Edge Transport servers to insert message files directly into the transport pipeline. Correctly formatted email message files that you copy to the Pickup or Replay directories are submitted for delivery. The Pickup directory is used by administrators for mail flow testing, or by applications that must create and submit their own messages. The Replay directory receives messages from non-SMTP foreign gateway servers and resubmits messages that you exported from the queues of Microsoft Exchange servers.

  • Estimated time to complete: 15 minutes

  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Transport service" entry in the Mail Flow Permissions topic.

  • You can only use the Shell to perform this procedure.

  • The value of the PickupDirectoryMaxMessagesPerMinute parameter on the Set-TransportService cmdlet is used by the Pickup and Replay directories.

  • Changing the location of the Pickup or Replay directories doesn't copy any existing message files from the old location to the new location. The new Pickup or Replay directory location is active almost immediately after the configuration change, but any existing message files are left in the old location.

  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard Shortcuts in the Exchange Admin Center.

To configure the Pickup directory, use the following syntax.

Set-TransportService <ServerIdentity> -PickupDirectoryPath <LocalFilePath> -PickupDirectoryMaxHeaderSize <Size> -PickupDirectoryMaxRecipientsPerMessage <Integer> -PickupDirectoryMaxMessagesPerMinute <Integer>

This example makes the following changes to the Pickup directory on the Mailbox server named Exchange01:

  • The Pickup directory location is set to D:\Pickup Directory.

  • The maximum size allowed for message headers in a message file is increased to 96 KB.

  • The maximum number of recipients allowed in a message file is increased to 250.

  • The maximum rate of message processing for the Pickup and Replay directories is increased to 200 messages per minute.

Set-TransportService Exchange01 -PickupDirectoryPath "D:\Pickup Directory" -PickupDirectoryMaxHeaderSize 96KB -PickupDirectoryMaxRecipientsPerMessage 250 -PickupDirectoryMaxMessagesPerMinute 200
NoteNote:
  • Setting the PickupDirectoryPath parameter to the value $null disables the Pickup directory.

  • The directory specified by the PickupDirectoryPath parameter and the ReplayDirectoryPath parameter can't be the same.

To configure the Replay directory, use the following syntax.

Set-TransportService <ServerIdentity> -ReplayDirectoryPath "C:\Replay Directory" <LocalFilePath> -PickupDirectoryMaxMessagesPerMinute <Integer>

This example makes the following changes to the Replay directory on the Mailbox server named Exchange01:

  • The Replay directory location is set to D:\Replay Directory.

  • The maximum rate of message processing for the Pickup and Replay directories is increased to 200 messages per minute.

Set-TransportService Exchange01 -ReplayDirectoryPath "D:\Replay Directory" -PickupDirectoryMaxMessagesPerMinute 200
NoteNote:
  • Setting the ReplayDirectoryPath parameter to the value $null disables the Replay directory.

  • The directory specified by the PickupDirectoryPath parameter and the ReplayDirectoryPath parameter can't be the same.

To verify that you have successfully configured the Pickup and Replay directories, do the following:

  1. Run the following command:

    Get-TransportService <ServerIdentity> | Format-List Pickup*,Replay*
    
  2. Verify the values displayed are the values you configured.
