In Short: Fabric Data in Teams and Outlook
Fabric IQ is the integration layer between your Microsoft Fabric data estate and Microsoft 365 Copilot. It surfaces intelligence from your Fabric semantic models, OneLake data, and Rayfin directly through the natural language interface of Copilot in Teams and Outlook - allowing business users to ask data questions and receive governed, accurate answers without opening a Power BI report.
For Power BI users specifically, Fabric IQ changes the consumption model: instead of logging into Power BI to check a metric, business users can ask Copilot in Teams or Outlook a question in plain language and get an answer sourced from the same semantic model that powers your reports.
What Fabric IQ Is (and Is Not)
Fabric IQ is not a separate product and not a new data store. It is the connection layer that routes natural language questions from Microsoft 365 Copilot to your specific, published Fabric semantic models - and returns governed, accurate answers based on those models.
The important distinction from general Copilot responses is governance. Fabric IQ does not use the model's training data to approximate an answer. It queries your specific semantic model - the one your BI team built, with your defined measures, your RLS rules, and your sensitivity labels applied. The answer a business user gets from Copilot via Fabric IQ is the same answer they would get from the equivalent Power BI report, filtered to their authorised data access.
What Changes for Business Users
The immediate change is the elimination of the "log into Power BI to check the number" step. Business users with a specific question can ask it in Teams, get a governed answer, and continue their workflow without context-switching to a BI tool.
For executives and senior decision-makers who use Power BI primarily to look up specific numbers rather than to explore data in depth, Copilot via Fabric IQ is a more natural interaction model than opening a report. A CFO asking "What was our Q2 EMEA gross margin versus budget?" gets an accurate answer in the Teams conversation they are already in.
Fabric IQ also generates chart summaries - natural language explanations of what a Power BI visual shows, including trend interpretation and anomaly callouts. For users who receive a Power BI report in an email and need a quick summary before a meeting, these summaries reduce the time to insight without requiring the user to open and interpret the visual themselves.
What Changes for Power BI Report Builders
Fabric IQ creates a direct feedback mechanism between semantic model quality and business user experience that standard report usage never created.
When business users ask Copilot questions and receive answers from your semantic model, the quality of those answers depends entirely on measure naming clarity, relationship correctness, and metadata completeness. A measure named "Rev_adj_v3" will not be matched correctly to a user asking about "adjusted revenue." A measure named "Adjusted Revenue" with a clear description will be.
Fabric IQ is, in this sense, a forcing function for the semantic model quality discipline that BI best practices have always recommended but business reality rarely enforced. Report builders will see, through direct user feedback, when their model naming is ambiguous or their relationship structure produces incorrect query results.
What Changes for BI Architects
Fabric IQ changes the query profile of semantic models. Models that previously served visual interactions in Power BI reports will increasingly serve conversational query traffic through Copilot - a different access pattern with different performance characteristics.
Architects need to ensure models optimised for report interactions are also optimised for the question-and-answer interaction pattern of Copilot. Direct Lake mode is particularly important here: it provides the query performance needed to serve Copilot responses with acceptable latency for conversational interactions.
Row-level security configuration also becomes more visible. With standard report access, incorrect RLS typically shows up as a support ticket ("I can't see region X"). With Fabric IQ, incorrect RLS shows up as Copilot producing incorrect or incomplete answers to data questions, which may not be immediately identified as an access control problem.
Prerequisites for Fabric IQ
To get full Fabric IQ capability through Microsoft 365 Copilot:
- Microsoft Fabric capacity (F-SKU) - required for Direct Lake and the Rayfin intelligence layer
- Microsoft 365 Copilot licences - required for Teams and Outlook Copilot interface access
- Published Power BI semantic models in Fabric workspaces with appropriate sharing and discovery settings
- Semantic model quality - measures named in business language, relationships correctly defined, RLS configured accurately
Organisations with well-governed Fabric estates and mature semantic models can activate Fabric IQ and see value immediately. Organisations without those foundations will surface their data quality and governance gaps through Copilot responses more visibly than any internal audit would.
Preparing Your Semantic Models for Fabric IQ
The preparation sequence before activating Fabric IQ:
First, audit published semantic models for measure naming quality. Every measure a business user might ask about should have a name recognisable without knowledge of the underlying data model.
Second, verify that RLS is correctly configured on every model that Fabric IQ will query. Test RLS with representative users from different roles before activating Copilot access.
Third, enable Fabric IQ in the Microsoft 365 Admin Centre and conduct structured testing with a representative set of questions from actual business users. Real user questions are consistently different from the questions BI teams predict they will ask.
Our Power BI consulting team and Fabric implementation practice prepare semantic models and Fabric estates for Fabric IQ activation as part of Power BI and Fabric engagement work.
