About this tag
The teams apps tag brings together updates and guidance about extending Microsoft Teams with tabs, bots, and message extensions, including where those apps can be used. Current coverage focuses on the expansion of Teams apps into Private Channels for standard Microsoft 365 tenants, making these channels more capable work surfaces across desktop clients on Windows and Mac. It also follows the retirement of Microsoft Graph Toolkit and the resulting need to review SharePoint Framework and Teams web parts that depend on it for authentication, permissions, Graph data, or user-facing workflows. Expect practical context on app capability changes, migration planning, supported replacements, and managing unsupported dependencies.
