Rule Name

Initialization of outbound authentication failed with the specified error for the Send connector.


This Error event indicates that the specified Send connector on the Hub Transport server or Edge Transport server experienced an authentication credential initialization failure with the specified remote server.

When a Send connector is configured to route outbound messages to a smart host, the following authentication methods are available:

  • None

  • Basic authentication

  • Basic authentication over Transport Layer Security (TLS)

  • Exchange Server authentication

  • Externally Secured

In the Exchange Management Console, you set the authentication methods for outbound connections to a smart host on the Configure smart host authentication settings page after you click Change on the Network tab of the Send connector properties page.

In the Exchange Management Shell, you set the authentication methods for outbound connections to a smart host by using the SmartHostAuthMechanism parameter on the Set-SendConnector cmdlet.

User Action

To resolve this error, do one or more of the following:

  • Verify that the Send connector and the destination smart host are configured to use a common authentication method with the correct credentials and required certificates.

  • Re-enter the username and password on the specified Send connector and at the remote server.

  • Make sure that the server that logged this event can connect to the specified remote server. For example, use the Ping or PathPing command-line tools to test basic connectivity. Use Ping to isolate network hardware problems and incompatible configurations. Use PathPing to detect packet loss over multiple-hop trips.
