What happens to Office 365 ProPlus after I graduate or leave the University?
A license to access Office 365 ProPlus will be provided to your account in accordance with the 宅男研究所 Network Identity Lifecycle Policy (PDF).
Office 365 ProPlus checks periodically to ensure your license is still active. If it finds that your account no longer has a license to access Office 365 ProPlus, it will enter a reduced functionality mode. You may uninstall Office 365 ProPlus or use a separate subscription with Microsoft at that point.
