Message: IPv6 is not supported. Binding: %1
   
Explanation

This Error event indicates that the following conditions are true:

  • An IPv6 address is configured on the local network interface. Microsoft TCP/IP version 6 (IPv6) is supported in Microsoft Windows Server 2003 as a protocol. For more information, see Windows Server 2003 IPv6.

  • A Receive connector is configured to listen for inbound messages by using the IPv6 address interface.

The IP address and port number that are used by a Receive connector to listen for inbound messages can be specified by using the following methods:

  • The Bindings parameter on the New-ReceiveConnector cmdlet or Set-ReceiveConnector cmdlet in the Exchange Management Shell.

  • The Use these local IP Addresses to receive mail option on the Network tab of the Receive connector properties page in the Exchange Management Console.

   
User Action

To resolve this error, configure an IPv4 address on a local network interface, and configure the Receive connector to listen for inbound messages by using the IPv4 address. The IP address can be a true IPv4 address, such as 10.1.1.25, or an IPv4 address that is specified in IPv6 syntax, such as 0000:0000:0000:0000:0000:0000:0A01:0119.
