Microsoft 365 Copilot Readiness: What To Review Before Buying Licenses

Before buying Microsoft 365 Copilot licences, review whether users meet the technical requirements, whether their Microsoft 365 data is governed well enough, and whether the first licences will go to people who actively use Teams, Outlook, and Office documents. Buying first and checking later can leave licences assigned to users who are not ready to get value from them.

Copilot readiness is not only a licence question. It also depends on Exchange Online, Microsoft Entra ID, supported browsers and devices, network access, SharePoint and OneDrive permissions, sensitivity labelling, and a rollout plan that starts with the right group.

Confirm The Baseline Technical Requirements

Start with the requirements Microsoft identifies for deployment. Users need an eligible Microsoft 365 or Office 365 plan before a Copilot licence can be added. Their primary mailbox must be in Exchange Online because Copilot uses mailbox content and metadata for supported Outlook and calendar scenarios. Users also need a Microsoft Entra ID account, supported operating systems or browsers, and access to the required network endpoints.

This review should be done before the purchase decision, not after. A small business may have a mix of Business Basic, Business Standard, Business Premium, older Office installs, shared devices, and users who mainly work from mobile. Those differences affect who is ready for a pilot and who may need cleanup first.

If the business already relies on Microsoft 365 but is not sure which subscriptions, app update channels, or mailbox locations are in use, treat Copilot as a reason to tidy the tenant. OnlineV’s Microsoft 365 consulting work can support that kind of readiness review without turning it into a licence-only discussion.

Review Data Exposure And Compliance

Copilot honours existing Microsoft 365 permissions. That is helpful, but it also means overshared files can become easier for authorised users to discover. Before enabling Copilot broadly, review SharePoint sharing settings, site ownership, unused sites, broad permissions, and business-critical sites. OneDrive should be included because OneDrive uses SharePoint Online underneath and tenant-level sharing controls can affect both services.

The goal is not to hide useful company knowledge. The goal is to make sure normal permissions still reflect current business reality. Old project sites, anonymous links, departed owners, and broad groups can all create confusion. If an employee is allowed to access a file, Copilot may be able to use that access in supported responses. The permission model should be intentional before the assistant is introduced.

Check Information Protection

Microsoft describes Copilot as operating within the Office 365 trust boundary and honouring existing security, compliance, and privacy controls. That does not remove the need to configure those controls. Review whether sensitivity labels are being used where appropriate, whether protected documents rely on modern labelling rather than legacy Information Rights Management, and whether audit expectations are clear.

For many small businesses, the practical question is simple: can staff already access only the documents they should access? If the answer is uncertain, pause the licence purchase and fix the most obvious data-governance issues first. A Copilot pilot should not be the first time the company discovers that old HR files, finance folders, or client contracts are visible to too many people.

Use The Readiness Report To Choose Pilot Users

The Microsoft 365 admin centre includes a Copilot readiness report. Microsoft says it helps identify technically eligible users, monitor app usage tied to Copilot scenarios, assign licences, and export readiness data. The report includes information such as prerequisite licences, app update channels, assigned and available Copilot licences, and user activity across Teams meetings, Teams chat, Outlook email, and Office documents.

For a small-business pilot, that data matters. A first pilot should usually include people who already work heavily in Microsoft 365, can give practical feedback, and are not blocked by missing prerequisites. The readiness report can help separate enthusiastic users from ready users. It can also expose basic housekeeping tasks, such as devices not on an eligible update channel.

Use the report as input, not as an employee-performance scorecard. Microsoft notes that suggested candidate information is intended to support rollout planning, not to evaluate employee performance. Keep the conversation focused on technology readiness and workflow fit.

Small-Business Scenario: Ten Licences, Twenty Interested Users

A 45-person professional services firm wants to buy ten Copilot licences because managers have seen demos in Word, Outlook, and Teams. The office manager, two sales staff, finance lead, operations coordinator, and several project leads all ask for access. A readiness review shows that some users have eligible plans and heavy Teams and Outlook usage, but others use older Office builds or store key files in poorly governed SharePoint sites.

The better first move is not to buy licences for the loudest requests. The business picks a pilot group whose mailboxes are in Exchange Online, devices are on an eligible update channel, and work depends on Teams, Outlook, and Office documents. At the same time, it fixes obvious oversharing in finance and project sites. The pilot starts smaller, but the company learns from users who are actually ready.

Pre-Purchase Decision Checklist

• Confirm the users have eligible Microsoft 365 or Office 365 prerequisite licences.
• Check that pilot users’ primary mailboxes are in Exchange Online.
• Confirm Microsoft Entra ID accounts, supported browsers, supported mobile platforms where relevant, and required network access.
• Review whether desktop apps are on an eligible update channel for the users being considered.
• Inspect SharePoint and OneDrive sharing, site ownership, unused sites, and broad permissions.
• Review sensitivity labelling and any compliance controls that should apply to important content.
• Use the admin readiness report to select pilot users who are both technically eligible and active in Microsoft 365 work.
• Decide what feedback the pilot should produce before more licences are purchased.

Common Mistakes Before Buying

• Buying licences before confirming mailbox, subscription, app, and network requirements.
• Assigning licences to executives or managers who are interested but not technically ready.
• Ignoring SharePoint and OneDrive permissions because Copilot is viewed only as an app feature.
• Starting with too many users before support, training, and feedback channels are clear.
• Treating the readiness report as a ranking of employee quality instead of a rollout planning tool.

Another mistake is making the purchase decision separate from Microsoft 365 operations. Copilot touches the same tenant foundation as mail, files, identity, Teams, and compliance. If those areas are messy, the readiness work should include cleanup, not just procurement. Related planning may also connect to cloud management and ongoing Microsoft 365 support.

Next Step: Review One Pilot Group First

Pick one realistic pilot group and review its licences, mailboxes, app update channels, SharePoint access, OneDrive exposure, and readiness report details before buying. If that group is not ready, fix the tenant foundation before expanding the budget. If it is ready, buy only enough licences to run a measured pilot and define what successful adoption should look like.
