Event details
When I open the Purview DSI first time a Window appears to acknowledge to move forward. In that Windows it states "Note: While using Data Security Investigations, selected M365 data will be shared with Microsoft Security Copilot for AI processes."
What does means on paid M365 customer tenants? General security terminilogy is given but I'm really keen to know if Microsoft AI will leveraged customer's documents to identify and learn and optimize their engine?

Hey Susanthasilva,
No, customer data in data security investigation is NOT used to train or optimize our models. That message is in reference to internal compliance boundaries that may differ from other purview products.
From our public documentation here:
"To ensure user privacy, all data sharing, logging, and scanning is turned off by default for Microsoft Security Copilot processing of Data Security Investigations data."
