Question 140
A client wants recipients to open protected email from non-Microsoft mail providers. Which response most directly addresses the stated need?
Explanation
Correct Answer
Encrypted recipients can access content using supported Outlook or authenticated portal experiences. It directly meets the case's requirement to allow cross-provider encrypted reading.
Incorrect Answers
Do Not Forward adds rights-management restrictions beyond encryption-only confidentiality. That would restrict forwarding of protected email; the question instead requires a way to allow cross-provider encrypted reading.
Supported Outlook interfaces let end users choose message encryption for individual emails. That would encrypt a single message manually; the question instead requires a way to allow cross-provider encrypted reading.
Mail flow rules can apply message encryption when specified content and recipient conditions match. That would automatically encrypt matching outgoing mail; the question instead requires a way to allow cross-provider encrypted reading.
