# Rolling Out Microsoft 365 Copilot? Fix Oversharing Before It Surfaces Your Files

Copilot can only see what each person can already open, so overshared SharePoint sites, Teams and “anyone” links become easy to find through it. Before rolling it out, review broad sharing, tighten site permissions, label sensitive files and start with a small pilot group.

- **Starting price:** From $500

- **Where:** Remote, anywhere in the U.S.

- **Quote:** Fixed price before work starts

## Try this first

- List sites and files shared with everyone or through open links
- Remove broad links and tighten site membership
- Move HR, finance and legal files to restricted locations
- Apply sensitivity labels to confidential files
- Start Copilot with a small pilot group
- Review what pilot users can find before expanding

Common causes

- Sites shared with everyone in the company
- “Anyone with the link” and company-wide links left open
- Sensitive files stored in team sites with broad access
- No sensitivity labels or retention policies

## When it’s more than a quick fix

If you handle health, financial or HR data, or have years of unmanaged sharing, run a proper access review before anyone gets Copilot.

### How we fix it remotely

We review sharing across SharePoint, Teams and OneDrive, lock down what’s overshared, set up labels and run a safe Copilot pilot.
