MSMQT Deprecation
The MSMQT feature has been removed from BizTalk Server. In Orchestration Designer, the MSMQT transport option remains available in the design-time Port Configuration Wizard as shown in the image below when you choose the Specify now option for Port binding.

BizTalk Server Projects
New BizTalk Server projects should not use the MSMQT transport option. Application deployment to BizTalk Server will fail with the error Protocol type “MSMQT” not found.
Migrated BizTalk Server Projects
BizTalk Server projects can be migrated to BizTalk Server by using the Visual Studio Conversion Wizard as documented in Migrating a BizTalk Server Project. Projects containing ports configured to use the MSMQT transport must be manually reconfigured before deployment to BizTalk Server. The recommended reconfiguration is to use the MSMQ adapter. For more information about the MSMQ adapter see What Is the MSMQ Adapter?.
