Microsoft moves Copilot Cowork from preview to general availability

Copilot Cowork reached general availability on 22 June. The update added support for the GPT 5.5 model, improved skill management, and the ability to run inside the Edge browser. The change also refreshed the interface and positioned the tool for multi-step work across Microsoft 365 apps. Access still requires a Microsoft 365 Copilot licence. Microsoft states the move takes agent-style assistance out of the experimental Frontier programme and into standard enterprise release.
Before this release, most builders treated Copilot features as optional experiments that could be ignored without consequence. The output was often incomplete or unsafe, so the cautious approach was to keep it at arm's length. General availability changes the expectation inside organisations. Colleagues and managers now assume the assistant is ready for real work, which pressures makers to use it even when they cannot yet judge whether the generated formulas, data calls, or approval flows will survive actual list sizes and permissions.
Analysis
Stop treating Copilot output as a head start. Run every generated Patch, Filter, or approval step against your largest SharePoint list right now and discard anything that triggers delegation warnings or hidden record limits.
