What Does Microsoft 365 Copilot Do?
The technology company said Tuesday that Microsoft 365 Copilot blends advanced large language models with the Work IQ intelligence layer to deliver context-aware assistance in Word, Excel, PowerPoint, Outlook and Teams. It works to enable agencies to draft responses, summarize case files, analyze spending trends and develop compliant budget reports within Microsoft 365 tools.

It ships with web grounding disabled by default to maintain the confidentiality of sensitive government data within GCC-High.
