New-DlpFingerprint

Exchange Online ExchangeOnlineManagement New-*

For more information, see Security & Compliance PowerShell. Use the New-DlpFingerprint cmdlet to create document fingerprints that are used with data loss prevention (DLP) sensitive information types in the Microsoft Purview compliance portal. Because the results of New-DlpFingerprint aren't stored outside of the sensitive information type, you always run New-DlpFingerprint and New-DlpSensitiveInformationType or Set-DlpSensitiveInformationType in the same PowerShell session.
