¹ The SendSafely Add-in for Outlook is only available and supported for use by Microsoft work and school accounts whose administrator has installed the add-in via the Microsoft 365 admin center.   The SendSafely Add-in is NOT supported for use by Microsoft personal accounts or work and school accounts where the user installed the add-in directly through the Office Store (not using the Microsoft 365 admin center). If you are unsure which type of account you have, consult this link: What's the difference between a Microsoft account and a work or school account?
