Message routing latency if IPv6 is enabled in Exchange Server 2013

Symptoms

By default, IPv6 is enabled in Windows. If IPv6 addressing is configured to use link-local addressing, there is a time-based latency in delivering messages in Microsoft Exchange Server 2013. This occurs because the computer tries to resolve the IPv6 address record (AAAA record).

Resolution

To resolve this issue, install the following update:
2961810 Cumulative Update 6 for Exchange Server 2013

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
