eDiscovery case (Premium) and on-premise file share content
You cannot have an on-premise file share as a data source. The only option you have is to search the external data and group the data into folders by custodian. Then you load the non-Microsoft 365 data into Microsoft 365 as part of an eDiscovery Premium Review set to a designated custodian. Then, when you search the review set for the custodian data, you see the option for the non-Microsoft data. The details are here Load non-Microsoft 365 data into a review set | Microsoft Learn
Thanks for your response. I understand that I cannot have on-premise file share as a data source. To bridge this gap, Microsoft recommended Graph connector agent which ingests data and makes the index available in o365 cloud for further use in its services. The documentation Microsoft website on using Graph connectors with eDiscovery (Premium) no longer exists. This is what it said before.
"Microsoft 365 customers can perform eDiscovery searches on content ingested for enterprise search. This support helps organizations improve their compliance posture to external content sources by bringing them within the purview of Microsoft compliance solutions. With Graph connectors, you can enable content from external data sources to be available to Microsoft Purview eDiscovery premium solution"
