This update adds support for Transport Layer Security (TLS) protocol version 1.2 to BizTalk Server.


This update is included in the following updates for BizTalk Server:

Cumulative Update 5 for BizTalk Server 2016

Cumulative Update 8 for BizTalk Server 2013 R2

Cumulative Update 7 for BizTalk Server 2013


SQL Server 2012 Native Client version 11 should be installed on all BizTalk Server systems before you apply this update. If the SQL Native Client is not installed before you apply cumulative update, the installation may not complete.

More information

TLS 1.2 is now fully supported in BizTalk Server. This includes all the adapters and accelerators. You can also disable SSL, TLS 1.0, and TLS 1.1 in BizTalk Server.

Key information:

  • Any external systems that communicate with BizTalk Server must also support TLS 1.2.

  • Any custom code, such as functoids, may have to be updated to support TLS 1.2.

For information about how to set up a TLS 1.2 environment, go to the "Option 1: Switch to the TLS 1.2 protocol" section of the following article in the Microsoft Knowledge Base:
