 As shared in the last communication, weintegrations are publishing guidance for owners of webhook-based connectors to update their URLsbuilt on a platform that can grow with a new structure. To allow ample time for replacing URLs, connector owners will have until January 31, 2025, which is an extension from our previous deadline of December 31, 2024. See below for complete guidance.

Webhook-based connectors within the O365 Connectors service in Teams are transitioning to a new URL structure due to the implementation of further service hardening updates. During this transition, you may receive notifications to update your configured connector to use the new URL. We strongly recommend that you update your connector immediately to prevent any disruption to connector services. URLs for all webhook-based connectors must be updated by January 31, 2025 for the connectors to continue posting messages into Teams. Keep in mind the entire O365 Connectors service in Teams will be retired at the end of 2025, so consider moving your webhooks to the Workflows app within Teams to avoid conducting another migration.
