❓ Frequently Asked Questions
Why is the MailItemsAccessed event so critical for the MS-102 exam?
It is the primary differentiator. Standard auditing shows a login occurred, but only Premium proves if a specific email was opened, which is vital for legal breach notification requirements.
Can I recover audit logs from before I upgraded to Premium?
No, Audit (Premium) features and extended retention apply only to events generated after the license is assigned and the feature is enabled in the tenant.
