The MicrosoftTeams addon allows Unleash to post Updates when a feature toggle is updated. To set up this addon, you need to set up a webhook connector for your channel. You can follow [Creating an Incoming Webhook for a channel](https://docs.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-incoming-webhook) on how to do that.
The Microsoft Teams addon will perform a single retry if the HTTP POST against the Microsoft Teams Webhook URL fails (either a 50x or network error). Duplicate events may happen, and you should never assume events always comes in order.
