Hi maxwell.2k19 ,
Thank you for choosing Microsoft Community.
This behaviour occurs because creating a Power Pages site requires the ability to create an Azure AD app registration.
Even with full Dataverse permissions, the site creation process will fail if the user does not have the necessary Azure AD rights.
To resolve this, one of the following must be in place:
-Assign the user the Azure AD “Application Developer” role– This grants permission to create app registrations and is the most common fix.
-Enable “Users can register applications” in Azure AD tenant settings – This allows all users to create app registrations without assigning a role.
Have an Azure admin pre‑create the required app registration– This avoids granting the user any Azure AD role, but requires manual setup.
Once the app registration requirement is met, the user will be able to create the Power Pages site without further issues.
