Why Microsoft 365 app permissions can put your business at risk

Installing an app in Microsoft 365 may seem routine, but the permissions behind that click can create serious business risk. A third-party app can request access to company email, files, teams conversations, calendars, contacts, and directory data. In some cases, that access goes far beyond one employee’s account.

That is why app approval in Microsoft 365 should never be treated as a minor step. Without the right controls, one approval can expose sensitive information, create compliance concerns, and increase the likelihood of consent phishing attacks.
