Microsoft Exchange Online Connector (Labs)

Connects to Microsoft Exchange Online using the entered account. Once connected you can use various nodes to work with your email such as the Email Reader node to read email or the Email Sender node to send email.

This node uses the Jakarta Mail API and the Angus Mail implementation to interact with the Microsoft Exchange Online servers.
