Is it true that the Send Outlook Mail Message activity will function without having Microsoft Outlook installed?

The Send Outlook Mail Message activity is designed to interact directly with Microsoft Outlook and relies on the Outlook application being present on the machine to function properly. This activity utilizes Microsoft Outlook's COM interface to send emails. Without Outlook installed, the activity cannot establish a connection to the email application, and therefore, it will not be able to send messages.

In scenarios where only online email services or different email clients are needed, other activities within RPA tools may be more suitable. For instance, when working with SMTP, activities can send emails without requiring Outlook; however, that is distinct from the specific capabilities of the Send Outlook Mail Message activity. Consequently, the correct assertion is that having Microsoft Outlook installed is a prerequisite for the activity to operate effectively.
