Correct Answer: AIn Microsoft Office 365 Advanced Message Encryption, whether a recipient receives a link-based experience or an inline experience depends on the recipient's identity type. Recipients using work or school accounts from Office 365 or Microsoft 365, as well as those using Microsoft accounts (e.g., outlook.com users), receive an inline experience and thus cannot have their encrypted emails revoked. On the other hand, recipients using other types of accounts, such as Gmail, receive a link-based experience, which allows the sender to revoke the encrypted email. In this scenario, the only recipient who receives a link-based experience and can have their email revoked is Recipient4, who uses a Gmail address.
