Which activities can be used to send an email message?

The option focusing on sending an Outlook Mail Message is correct because it directly refers to the action of composing and sending an email through Microsoft's Outlook application. This action utilizes specific activities designed to interact with Outlook, allowing users to create, format, and send email messages programmatically. This capability is crucial in robotic process automation (RPA) scenarios where automated communication is necessary, such as sending notifications, alerts, or reports to users.

In contrast, the activity to send a Microsoft Teams Message relates exclusively to transmitting messages within the Teams platform, which does not equate to sending traditional email. Similarly, sending an SMS Message implies delivering text messages, typically via mobile networks, rather than an email format. On the other hand, sending a System Notification typically involves alerting users within a specific application environment or system, again differing significantly from email communication. Therefore, the ability to send an email message is solely encapsulated in the option addressing Outlook Mail.
