PL-900 Practice Question: Manage the Microsoft Power Platform environment
You are a Power Platform administrator. A user reports that they are unable to share a canvas app with external users. What is the most likely cause?
⚠ Common exam trap
Many candidates confuse environment-level sharing settings with licensing requirements or DLP policies, assuming that external sharing is always available or that a license is the primary blocker, when in fact the environment setting is the first gate.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The environment is not enabled for external sharing.
External sharing of canvas apps is controlled at the environment level in the Power Platform admin center. By default, external sharing is disabled for environments, and an administrator must explicitly enable it under the environment's settings. Without this setting enabled, users cannot share canvas apps with external users, even if they have the appropriate permissions.
