Address Validation for Dataverse can run Melissa Personator and Melissa Global in classic workflow processes. This is useful for validating existing records, or data created or updated by external processes such as portals or integrations.
In the workflow designer, select Add Step > Melissa > Personator Check or Global Check, and select your Field Mapping record in the step properties. The Field Mapping defines the table, the columns and the Melissa options, including the Melissa Blocking Result Codes.
For details, see Configure Melissa Personator and Configure Background Address Validation: Field Mapping and Workflows. To use Power Automate instead, see Melissa Personator or Melissa Global.
