 ### Usage
 
-1. Add `MS_TEAMS_WEBHOOK_URI` on your repository's configs on Settings > Secrets. It is the [webhook URI](https://docs.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-incoming-webhook) of the dedicated Microsoft Teams channel for notification.
+> [!WARNING]
+> Microsoft has [retired the legacy Office 365 connectors / incoming webhooks](https://devblogs.microsoft.com/microsoft365dev/retirement-of-office-365-connectors-within-microsoft-teams/). URLs that look like `https://*.webhook.office.com/...` or `https://outlook.office.com/webhook/...` are no longer delivered. A Workflows-based webhook (below) is required.
 
-2) Add a new `step` on your workflow code as last step of workflow job:
+1. Create a **Workflows-based incoming webhook** in Microsoft Teams and add it as the `MS_TEAMS_WEBHOOK_URI` secret in your repository's **Settings → Secrets and variables → Actions**. See [Create webhooks using Workflows](https://learn.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-incoming-webhook?tabs=dotnet#create-webhooks-using-workflows) in the Microsoft Learn docs for instructions.
