Issue Status: RESOLVED

Issue Description: Some users may experience failures when attempting to connect to Microsoft Fabric

More info: Users connecting to Microsoft Fabric (Data Warehouse) without specifying a database may land on the master database by default. When users run three-part queries (e.g., dbname.dbo.table) from the master database, the query fails with an error message. As a result, users are unable to successfully execute those queries unless they specify or switch to the correct database first.

As a workaround, users can specify the database name in connection properties or add a new line “USE ” while querying from database.

Final Update: 15/06/2026 08:48:00 AM –Microsoft has confirmed that after reverting the recent change and monitoring service telemetry, the issue is no longer occurring.

Scope of impact: Impact is specific to some users in the United States and the United Kingdom who are attempting to connect to Microsoft Fabric.

Root cause: A recent service change in Microsoft Fabric connectivity layer altered the default database selection behaviour, causing queries to fail for some users and resulting in impact.

Next steps: Microsoft are reviewing our update procedures to better identify similar issues during our development and testing cycles.
