Microsoft 365 Copilot & AI Readiness Guide for SMEs

Why AI Readiness Comes Before Licensing

Microsoft 365 Copilot can save employees hours each week by summarising Teams meetings, drafting client proposals in Word, and analysing financial trends in Excel. However, Copilot inherits every user's existing Microsoft Graph permissions. If your SharePoint sites or OneDrive folders are over-shared, Copilot will surface sensitive HR, payroll, or board documents in seconds.

Step 1: Audit SharePoint & OneDrive Permissions

• Remove "Everyone except external users" and broad company-wide sharing links from confidential SharePoint sites
• Separate HR, Finance, Executive, and Legal libraries into dedicated security-group-restricted sites
• Audit guest accounts and expire stale external sharing links in Microsoft Entra ID
• Enforce least-privilege access across all Microsoft Teams channels

Step 2: Deploy Microsoft Purview Information Protection

• Define clear sensitivity labels (e.g., Public, Internal, Confidential, Highly Confidential — Board Only)
• Configure auto-labelling policies for UK GDPR personal data, financial records, and client contracts
• Apply encryption and watermarks to "Highly Confidential" labels so Copilot cannot summarise or extract their contents into unlabelled documents
• Enable Data Loss Prevention (DLP) policies to block sensitive prompts from leaving your tenant

Step 3: Licensing & High-ROI Pilot Selection

• Verify prerequisite licensing (Microsoft 365 Business Standard, Business Premium, E3, or E5)
• Start with a 5–15 user pilot group across high-impact roles (fee earners, account managers, operations leads, finance)
• Establish an Acceptable Use Policy for Generative AI covering data privacy and human verification
• Track weekly time savings and adoption metrics before expanding licences across the wider organisation
