Improvements and fixes

This security update contains the following nonsecurity improvements and fixes:
  • Increases the number of retries when trying to connect to a host in Outlook 2013. By default, WinHTTP will try six IP addresses (one initial attempt and five retires) when it tries to establish a connection to a host. If Outlook 2013 tries more than six IP addresses, the connection fails. This is particularly problematic on networks that has intermittent IPv6 connectivity problems. Increasing the number of retries lets the connection succeed when using IPv4 addresses. To enable this feature, see KB 3178716 for more information.
  • Adds an Insert Link button in the action bar of the chat input area of the IM window in Skype for Business 2015 (Lync 2013).
  • Provides a corrected translation of Outline View in PowerPoint 2013 for Danish.
