Save and Activate the Scenario
After configuring Microsoft Outlook, Slack, and any additional nodes, donโt forget to save the scenario and click "Deploy."

Test the Scenario
Run the scenario by clicking โRun onceโ and triggering an event to check if the Microsoft Outlook and Slack integration works as expected. Depending on your setup, data should flow between Microsoft Outlook and Slack (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
