This topic explains how to troubleshoot an issue in which the Microsoft Exchange POP3 service or the Microsoft Exchange Transport service on an Exchange Server 2007 Hub server does not start.

When you try to restart the Microsoft Exchange POP3 service or the Microsoft Exchange Transport service on an Exchange 2007 Hub server, the services do not start. One or more of the following error events may be logged in Event Viewer:

Event Source: MSExchange POP3 service

Event Category: ProcessManager

Event ID: 1019

Description:

Failed to start listening (Error: 10049). Binding: <IP address>:110.

Event Source: MSExchange TransportService

Event Category: ProcessManager

Event ID: 1019

Description:

Failed to start listening (Error: 10049). Binding: <IP address>:25.

Note:
The Microsoft Exchange Transport service can be started in Exchange 2007 SP1 even if event ID 1019 is logged.

This issue occurs if the POP3 service is not configured to listen on a local IP address or if the receive connectors for the Transport service cannot bind to an IP address. To resolve this issue, configure the POP3 service to listen on a local IP address, and configure the receive connector to listen on all IP addresses.

To configure the POP3 service to listen on a local IP address
  1. Start Exchange Management Shell.

  2. Run the following cmdlet, and then press ENTER:

    set-popsettings -unencryptedortlsbindings "0.0.0.0:110" -sslbindings "0.0.0.0:995"

  3. Close Exchange Management Shell.

To configure a receive connector to listen on all IP addresses
  1. Start Exchange Management Console.

  2. Expand Server Configuration, and then click Hub Transport.

  3. Select Receive Connector, and then click Properties.

  4. On the Network tab, in the Use these local IP addresses to receive mail box, remove the IP address that the receive connector cannot bind to.

  5. Click Add, click Use all IP addresses available on this server, and then click OK.

  6. Click OK, and then close Exchange Management Console.
