Add-ins are mini applications that extend what you can do with Office, Microsoft 365, and SharePoint (2013 and 2016). For example, with Office add-ins you can use Wikipedia without leaving Word or get directions and maps right in Outlook. Add-ins are available for Access web apps, Word, Excel, Outlook, Project, PowerPoint, and SharePoint.

Important: New name for apps for Office: Office Add-ins. We're currently updating our products, documentation, samples, and other resources to reflect the platform name change from "apps for Office and SharePoint" to "Office and SharePoint Add-ins". We made this change to better distinguish the extension platform from Office apps (applications). While these changes are taking place, the dialogs and messages you see in your application might be different than what you see in this article.

Connectors for Office 365 Groups

Connectors are online apps, tools, and services, such as Twitter, Trello, or RSS, that you probably use every day to connect and collaborate, stay on top of current events, track projects, and so on. They're integrated with Microsoft 365 Groups and take just minutes to hook up. Connectors fall into a variety of categories to suit every type of user and team, from the information worker focused on interests (Bing News, RSS) or productivity (Trello, Asana) to developer automation tools, (BuildKite), to email marketing services (MailChimp), and so on. You can hook multiple connectors to a group, and when you hook up one or more connectors, they're available to everyone in the group. No additional steps required!

To get the full story, see Connect apps to your groups.
