Copilot can see what you can see: tidy up your sharing

Copilot only shows you content you already have permission to open. So files shared too widely can turn up in other people’s answers.

1. If Copilot shows you something you shouldn’t have access to, tell IT — don’t forward or open it further.
2. Check who can see your files: select the file, choose Details, then under Has access choose Manage access.
3. On the Links tab, remove any “Anyone” links you no longer need with Remove link.
4. Use Stop sharing for people who no longer need access.
5. You can’t switch an existing link from edit to view — delete it and create a new one.
6. When you share, choose “Specific people” unless there’s a good reason not to.
