MS DTC for Azure SQL Managed Instance - extending distributed transaction support (private preview) - Microsoft Tech Community

Today, Azure SQL Managed Instance supports cross-instance distributed transactions, meaning that you can run distributed transactions between multiple databases hosted on several managed instances.

The scope of this improvement can enable you to run distributed transactions between Azure SQL Managed Instance and other distributed transaction participants and that includes:

Azure SQL Managed Instance
SQL Server hosted anywhere
Relational Database Management Systems
Other software that can participate in distributed transactions, such as MSMQ.
