New-Fingerprint

Exchange Online ExchangeOnlineManagement New-*

This cmdlet is functional only in on-premises Exchange. **Note**: In Exchange Online, this cmdlet is replaced by the New-DlpFingerPrint cmdlet in Security & Compliance PowerShell. Use the New-Fingerprint cmdlet to create document fingerprints that are used with data classification rules. Because the results of New-Fingerprint are not stored outside of the data classification rule, you always run New-Fingerprint and New-DataClassification or Set-DataClassification in the same PowerShell session.
