Announcing General Availability of Single Sign-On (SSO) for Office Add-ins

We are excited to announce that the single sign-on (SSO) functionality for Office Add-ins is moving to General Availability with version 2008. This authentication service allows an add-in to automatically and securely sign in a user after being granted consent, providing a more convenient experience by reducing the number of times they are requested to sign in. SSO works with both work and school accounts as well as Microsoft accounts.
