Through extensive user research, we’ve identified what Microsoft 365 users value most for boosting productivity. They want uninterrupted workflows, an all-in-one workspace, and minimal context switching. With this insight, we evolved Microsoft 365 into a unified platform across Microsoft Teams, Outlook, Microsoft 365 app (formerly Office.com), and more. For you as a developer, this means broader user reach without needing to rewrite code for each host. For IT admins, it\u2019s about centralized app management. That’s why with manifest version v1.13+, apps will now automatically appear across multiple Microsoft 365 hosts<\/a>, making development smoother and more impactful.<\/p>\n

Here’s an example of how this new app experience would work: Picture two users, Kat and Daniela, working on a project in a collaborative design app called Relecloud. They kick things off during a Teams meeting, using Relecloud\u2019s configurable tab<\/strong><\/a> app capability. After the meeting, they keep the conversation going asynchronously via email in Outlook. Whenever they need to make changes to the project, they can simply open Relecloud\u2019s static tab<\/strong><\/a> directly within Outlook. Finally, when Kat feels the project is ready, she leaves a comment in Relecloud, and the app\u2019s bot<\/strong><\/a> automatically notifies Daniela in Teams.<\/p>\n

This new app experience requires a shift in how developers think. Instead of building for individual hosts, developers now create for the unified Microsoft 365 platform\u2014using modular app elements like static tabs, message extensions, configurable tab and bots. These elements adapt across hosts, delivering a seamless, consistent experience for users.<\/p>\n

To streamline building apps for Microsoft 365, we are improving developer documents, tooling and automated testing to facilitate the mindset shift from specific products to platform. At the core of this evolution is the new ability to specify runtime requirements in your app manifest<\/strong>\u2014a key feature that optimizes functionality across hosts.<\/p>\n

Feature overview<\/h2>\n

So how does it work? The ability to specify runtime requirements in your manifest enables you to build apps that only show the relevant components supported by the host. Here’s a sneak peek of how this feature can enhance your app\u2019s versatility:<\/p>\n
