Your company is required to retain all emails sent to and from executives for 7 years due to regulatory compliance. You need to implement this with minimal administrative overhead. What should you use?
Retention policies automatically retain emails for the specified duration with minimal overhead.
Why this answer
Microsoft Purview retention policies and retention labels can automatically retain emails for a specified period. Option B (Litigation Hold) is a manual process for specific users. Option C (Journaling) exports emails to an external system, adding complexity.
Option D (Archive mailbox) provides storage but not automatic retention enforcement. A retention policy or label is the most efficient way.
