The correct answer to this question is B. Run the Set-OMEMessageRevocation cmdlet.
Explanation:
Microsoft Office 365 Message Encryption (OME) is a feature in Microsoft 365 that allows users to send and receive encrypted email messages. In this scenario, User1 has erroneously sent an email to user2@fabrikam.com, and you need to prevent user2 from accessing the email.
To achieve this, you can use the Set-OMEMessageRevocation cmdlet, which revokes access to an encrypted message that has already been sent. This cmdlet works by sending a revocation message to the recipient's email address, which prevents them from accessing the original message.
To use the Set-OMEMessageRevocation cmdlet, you need to have the appropriate permissions in your Microsoft 365 tenant. The cmdlet can be run from the Exchange Online PowerShell module or the Security & Compliance Center PowerShell module.
The correct syntax for the Set-OMEMessageRevocation cmdlet is as follows:
sqlSet-OMEMessageRevocation -Identity <MessageId> -Revoke In this syntax, <MessageId> is the identifier of the message that you want to revoke, and -Revoke is the parameter that specifies that the message should be revoked.
In summary, to prevent user2@fabrikam.com from accessing the email that was erroneously sent by User1, you should run the Set-OMEMessageRevocation cmdlet, which sends a revocation message to user2 and prevents them from accessing the original message.
