Microsoft now lets Copilot reach data in HubSpot and other external tools
Microsoft made federated connectors for Copilot generally available on 5 May 2026. The first wave covers HubSpot, LSEG, Moody’s and Notion, and works inside both standard Copilot and the Researcher agent. Custom plugins for Fabric and Dynamics 365 are also live. Broader partner connections and Excel support arrive later this summer.
Until now Copilot stayed inside the Microsoft 365 tenant. Users who already worry about Purview gaps knew the tool could only see what their licence already allowed, so the risk felt contained even if governance was incomplete. The new connectors change that boundary. External systems now feed directly into prompts and research tasks, which means any misconfigured permission can surface third-party records that compliance teams have not yet reviewed.
Analysis
Ignore the new connectors until your IT team confirms Purview rules cover every external source. Run one test in a sandbox tenant with dummy records first, then decide whether the added context is worth the extra oversight burden.
