What happens when someone clicks "Accept" in M365?

When a user approves an app in Microsoft 365, they may be granting that app permission to access business information stored across the organization’s environment. Depending on the permissions requested, the app may be able to read data, maintain ongoing access, or connect to services in ways that are not obvious at first glance. This is why the word "Accept" deserves more caution than many businesses realize. It is not simply a download or login step. It can be an access decision with real security implications.

Why this is a business risk, not just a user risk

Many people assume app permissions affect only the individual who installed the app. In Microsoft 365, that is not always the case. Some apps can request broad permissions that reach beyond one person’s mailbox or file storage.

That means one careless approval can increase risk for the wider organization, not just the employee who clicked the button. For businesses trying to protect sensitive data, maintain compliance, and reduce avoidable exposure, that makes app governance a leadership issue as much as an IT issue. 

What data can be at risk

Depending on the permissions granted, a risky Microsoft 365 app may be able to:

• Read company email
• Access OneDrive files
• View Teams conversations
• Read directory and user profile information
• Access calendars and contacts
• Maintain access event when the user is offline

How to reduce M365 app permission risk

Divergent IT recommends a clear and well-supported approach to controlling app permissions in Microsoft 365:

• Restrict user consent so employees cannot approve high-risk apps on their own.

• Allow apps only from verified publishers when appropriate.

• Require admin approval for apps requesting broad or sensitive permissions.

• Audit granted permissions regularly to identify unnecessary or risky access.

• Monitor application consent activity for unusual behavior.

• Document the app approval process so employees know how to request tools safely.

• Train employees to recognize suspicious app prompts and phishing tactics

These steps help businesses reduce risk while still making day-to-day work easier for employees who need approved tools to stay productive. 

Why app approval is a company responsibility

Application approval and consent policies are not only technical settings. They are business decisions. IT administrators can manage the technical controls, but leadership should define the approval process, acceptable risk levels, and accountability for allowing applications into the Microsoft 365 environment.

A dependable process helps answer important questions such as:

• Who is allowed to request a new app?

• Who reviews app permissions before approval?

• What level of data access is acceptable?

• How are approvals documented and reviewed over time?

Without those answers, businesses leave too much to chance.

Review your process and educate your team

If your organization already has a process for requesting administrator approval for an application, review it regularly. If the process changes, make sure the right people know what changed and what to do next.

That includes:

• Updating internal documentation.

• Adjusting monitoring and automation where needed.

• Communicating changes to users, IT teams, support staff, and developers.

Clear communication lowers confusion, supports compliance, and helps teams avoid risky workarounds.
