Error AADSTS5000225 means your Azure AD tenant was blocked due to inactivity. Microsoft does this for security and resource management, and you have 20 days from the block date to request reactivation—after that, the tenant and all its data are permanently deleted. To fix it, check the admin email for Microsoft’s unblock instructions, or open a support ticket via the Azure Portal or Microsoft 365 Admin Center. Act quickly, as delay may mean you’ll have to create a new tenant and reconfigure services like Azure DevOps from scratch.
