Most users do not understand that Microsoft 365 Copilot generates answers by pulling information through Microsoft Graph. Through this connection, Copilot is given access to services like Outlook, Teams, SharePoint, OneDrive, calendars, and even meeting transcripts. So, when users ask questions, Copilot searches the content they are already permitted to access. Hence, in managing information services, providing the correct access is essential before deploying Copilot.

Integral Part of Managing Information Services: Prepare Microsoft 365 Before Deploying Copilot
This initial step is crucial because Copilot does not add new permissions. Instead, it depends on the ones that already exist. As such, if an employee already has access to a file or folder, Copilot can summarize or reference that content. The concern, however, is not about Copilot itself but in checking if the permissions align with how people use information today. Oftentimes, businesses assume that their permissions are under control when years of staff turnover and quick decisions already tell another story.
Operational data, like project files, schedules, contracts, and the like, is stored in Microsoft 365 for many businesses. However, professional firms are even more challenged since their files contain data that is not just about their business but also their clients. Therefore, strict confidentiality is needed for client information, financial records, pricing agreements, employment documents, among others. That is why it is important to have the right partner in managing information services to ensure this is kept safe.
Typically, the problems begin with a little carelessness. For example, a staff member is given access to a project for a limited time. But, when the project is completed, the permission still exists, and the same employee can still open folders that are not related to their work tasks. This is just one example, imagine this scenario multiplied various times over the years and through all the employees that are or have worked with you. Eventually, no one will be able to track who can get access to what data. And experts in managing information services explain that, if access exists, Copilot can, unfortunately, use it regardless of the permission is still appropriate.
Microsoft acknowledges this problem. Hence, Copilot deployment framework should focus on three priorities: fixing oversharing, implementing security controls, and meeting AI compliance requirements.
Interestingly, oversharing is the first focus and is also the reason why Microsoft is making a strong point of cleaning permissions. Professionals in managing information services expound that the wrong access settings will impact all Copilot outputs. Furthermore, there is a risk that data can be exposed accidentally.
In another example, if someone asks Copilot about salaries and the payroll files are accidentally shared, Copilot can immediately summarize the information. As a result, a temporary access user may be able to access data months later when it is accessed by a hiring manager. The same issue can arise when it comes to client projects that may involve confidential information. Unfortunately, the same risks are present in other sites as Copilot can also find content from a shared OneDrive folder, a previous Teams channel, or a previously archived project. Thereby making information like employment records, pricing details, and commercial data visible when they are supposed to be confidential.
Experts in managing information services share four important details to check before deploying Copilot. First, a SharePoint sharing review should be done. This should include checking permissions, inactivity, and wide sharing on sites. With this, businesses usually see that access rights no longer match the current operational needs.
Second, review files that are shared externally through OneDrive. Usually, these links often remain active even after projects finish. Third, the team’s membership should be taken into consideration especially since the number of channels may increase during busy projects, but memberships do not usually decrease afterwards. Thus, exposing documents and conversations.
Lastly, classify sensitive information properly. Make sure to add sensitivity labels to differentiate confidential information from regular files by Microsoft. When combined with security policies, these labels can prevent Copilot from processing protected information altogether.
Normally, with a team that looks after managing information services it takes four to eight weeks to complete this for organizations of twenty-five to a hundred employees. For technical tasks, IT teams or AI business solutions providers like EB Solution should be able to do the job. However, it is important to note that it’s business decisions that will determine which files receive stronger protection. Thus, company leaders should be involved as they understand the value and sensitivity of data better than anyone else. This blend of technical and business knowledge results in greater security before deployment.
Before enabling Copilot, ask your IT provider if they are able to create a report that identifies files shared with high numbers of users. Clarify if this will include client data, salary records, or financial information. If they are able to provide a quick and meaningful answer. It is an indication that permissions are being actively managed. When the answer is not sure, or if the reporting features need to be enabled. Then, it means the environment has never been thoroughly reviewed from a permissions perspective.
