Azure Service Bus SBMP end of life & Microsoft BizTalk Server

Question

I see that the SBMP protocol for Azure Service Bus is going to be removed (not deprecated) in September 2026: https://techcommunity.microsoft.com/blog/messagingonazureblog/some-azure-service-bus-sdk-libraries-will-be-retired-on-30-september-2026%E2%80%94migrat/3917853

The problem with that, Microsoft BizTalk Server 2020 (under mainstream support until 2028) uses SBMP to talk to Azure Service Bus: https://learn.microsoft.com/en-us/biztalk/core/sb-messaging-adapter

Does anybody know a solution for this?

Answer 1

Hello @Alastair,

The SBMP protocol for Azure Service Bus will indeed be retired on September 30, 2026, which means it will no longer be available for use. Since Microsoft BizTalk Server 2020 relies on this protocol to communicate with Azure Service Bus, it is essential to consider alternative solutions.

One potential solution is to migrate to the latest Azure SDK libraries that support other protocols, such as AMQP. This would involve updating your BizTalk Server integration to utilize these newer libraries and protocols, ensuring continued compatibility with Azure Service Bus after the retirement of SBMP. This migration will ensure continued support and access to critical security updates and improved capabilities.

It's advisable to start planning the migration process to avoid disruptions when SBMP is no longer supported.

Also, for your better understanding kindly refer below links:
