As Microsoft continues to evolve its collaboration and productivity tools, many users are encountering changes in how Microsoft Teams integrates with Outlook—particularly when it comes to scheduling meetings. With the rollout of the New Teams and New Outlook experiences, the familiar functionality provided by the legacy Teams Meeting add-in is shifting. This article explains the current state of integration, outlines the transition phase, and highlights what organizations can expect in the near future as Microsoft moves toward a more streamlined, native meeting experience.
Current: Currently, full integration between Microsoft Teams and Outlook—specifically the ability to schedule Teams meetings directly from Outlook—requires the Classic Teams client and Classic Outlook. This functionality relies on a legacy COM add-in that is only available when Classic Teams is installed. If you’re using the New Teams client (the redesigned version), this add-in is not included or registered, meaning the “New Teams Meeting” button will not appear in Outlook. As of now, there is no native Teams scheduling support in Outlook when using the New Teams client.
Transition: Microsoft is actively transitioning away from the COM add-in model. In this phase, users who adopt the New Teams and New Outlook for Windows will begin to see native integration features slowly roll out. This means scheduling Teams meetings will no longer depend on the old add-in architecture and instead will be built directly into Outlook itself. However, as of mid-2025, this native experience is still in progress and not fully consistent across all clients and tenants, particularly in hybrid environments or those using legacy Office installations.
Future: Microsoft plans to provide seamless, built-in Teams meeting scheduling across all versions of Outlook—including desktop, web, and Mac—without the need for a separate add-in. This approach simplifies deployment and improves performance and reliability. Once complete, the New Teams and New Outlook clients will offer a fully integrated experience, making the legacy add-in obsolete. Until that future arrives, organizations needing dependable meeting scheduling through Outlook must continue using Classic Teams alongside Classic Outlook.
