This policy setting controls the security level for macros in Outlook. Macros are a single instruction that expands automatically into a set of instructions to perform a particular task. Available Policy Options: Always warn = This option corresponds to the "Warnings for all macros" option in the "Macro Security" section of the Outlook Trust Center. Rationale: To protect users from dangerous code, the disabling of macros that are not trusted, including unsigned macros, macros with expired or invalid signatures, and macros with valid signatures from publishers who are not on users' Trusted Publishers lists is recommended to help against would allow dangero... User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\outlook\security:level (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 3. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
