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. 

Power up with Office Add-ins @ Build 2020

We’re excited to announce new capabilities that let you create your own custom experiences in Microsoft 365, and enable your users to achieve more in the Office products they already use every day: Outlook, Excel, Word and PowerPoint.
