Will the Send Outlook Mail Message activity work without having Microsoft Outlook installed?

The Send Outlook Mail Message activity is specifically designed to interface directly with Microsoft Outlook as a mail client. This means that the activity relies on Outlook's functions and objects to compose, send, and manage emails. When Outlook is installed, the activity accesses the Outlook application programming interfaces (APIs) to perform these operations.

Without Microsoft Outlook installed, the activity will not have the necessary infrastructure or functionality to send emails, as it depends on the application's availability to process and send messages. Therefore, the absence of Outlook leads to the conclusion that executing this activity would not be possible, making it essential for users to have the application installed to utilize this feature effectively.

Other options relate to different scenarios that do not impact the core requirement of having Outlook installed for the activity to function. Only certain versions are not relevant here since the dependency on having Outlook installed is consistent across versions. Additionally, being connected to the internet does not change the fundamental requirement of needing Outlook on the system for the activity to operate.
