Data Days Hotline: No Slides, Just Answers  @MicrosoftReactor
Uploaded July 2026 | Updated September 2026, 3 weeks ago
This is not a polished talk. This is a hotline.

The questions come straight from the community. You send them in, we play them live, and our experts jump in to figure it out in real time. No scripts, no slides, no perfect answers, just honest help, ideas, and the occasional “let’s try this.”

Whether you’re stuck, curious, or just want to hear how others are solving things in Microsoft Fabric, SQL, Power BI, and AI, this is where it all comes together. You’ll learn something, hear different perspectives, and probably realize you’re not the only one asking that question.
