+Microsoft Teams. LibreNMS can send alerts to Microsoft Teams Connector API which are then posted to a specific channel. To configure the transport, go to:
+
+Global Settings -> Alerting Settings -> Microsoft Teams Transport.
+
+This can also be done manually in config.php :
+
+~
+```php
+$config['alert']['transports']['msteams']['url'] = 'https://outlook.office365.com/webhook/123456789';
+```

 Entities as described earlier are based on the table and column names within the database, if you are unsure of what the entity is you want then have a browse around inside MySQL using `show tables` and `desc <tablename>`.
