Copilot Is Surfacing Every File You Forgot Was Shared
Most SharePoint and Teams tenants carry a decade of “share with everyone” decisions: a salary spreadsheet in a site the whole company can read, an old HR folder inherited by a new department, a client contract sitting in a Teams channel that outlived the project. Nobody found those files because nobody was looking. Copilot looks. Ask it a question and it will happily quote from anything the asking user can technically open. Across Atlantic Canada we are seeing the same pattern: organizations turn Copilot on, get one uncomfortable answer in a demo, and switch it back off.
Benefit if You Get It Right
Cleaning up permissions before rollout turns Copilot into what it should be: a fast way to find the right document, draft the first version, and summarize the meeting you missed. You get the productivity gain without the “how did it know that” moment.
How VMG Helps
We run an oversharing report across SharePoint and OneDrive, fix the worst offenders, apply sensitivity labels to the files that matter, and set up Restricted SharePoint Search so Copilot only reads from sites you have reviewed. Then we pilot Copilot with a small group before anyone else gets a licence.
