Ensure 'Turn on administrator audit logging' is set to '<values>'

YüksekDüzey 1Otomatikexchange

Açıklama

Administrator audit logging is used to provide a log of the settings that are changed by administrators anywhere in the system. This recommendation incorporates the following parameters into one setting: • AdminAuditLogEnabled • AdminAuditLogCmdlets • AdminAuditLogParameters • AdminAuditLogExcludedCmdlets • AdminAuditLogAgeLimit • LogLevel Note: Changes to the audit log configuration may take up... Prints compliant when AdminAuditLogEnabled is True, AdminAuditLogCmdlets and AdminAuditLogParameters are '*', AdminAuditLogExcludedCmdlets is empty, AdminAuditLogAgeLimit is at least 90 days and LogLevel is Verbose. Run on each Edge Transport and Mailbox server. Run from an Exchange Management Shell or after `Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn`; the audit loads the snap-in itself when Get-ExchangeServer is missing and fails if it cannot.
