Rolling out Microsoft 365 Copilot: test first whether your staff are ready

Licences are the easy part

Many companies buy Microsoft 365 Copilot licences and find a few months later that some staff barely use it, while others use it readily but don't check the results. The difference is rarely technical and almost always about skills: giving a good instruction, checking a summary against its source, and knowing everything Copilot can see.

Copilot sees what the user can see

Microsoft 365 Copilot works with the data the user has access to, in Outlook, Teams, SharePoint and OneDrive. If permissions are too broad, Copilot can surface documents that weren't meant for that person. A permissions review belongs in the rollout, as do staff who know what to do when that happens.

Where it goes wrong in practice

A Copilot meeting summary that presents a decision differently from how it was made. An Excel analysis that misreads a column. An Outlook email that makes a promise that wasn't in the notes. Anyone who doesn't routinely check Copilot's output sends such mistakes out with the company's authority.

Measure before and after

At the start, measure how staff work with Copilot on tasks from their own work: checking a summary, reviewing an analysis, writing a clear instruction. Then give targeted lessons and measure again with different tasks at the same level. That shows whether the licences pay off and where you still need to adjust.

If your IT team builds agents in Copilot Studio, measure separately whether they keep rights and actions limited to what the task needs.
