Ensure the common attachment types filter is enabled in the default anti-malware policy

OrtaDüzey 1Otomatikm365

Açıklama

The common attachment filter blocks executable and script attachment types that are frequently used to deliver malware. Requires an already-connected Exchange Online session: Install-Module ExchangeOnlineManagement; Connect-ExchangeOnline (View-Only Organization Management is sufficient). The audit throws if no session exists.
