PAYG Services Like Purview DSI Can Rack Up Large Charges

Microsoft offers several PAYG services to Microsoft 365 tenants. Data Security Investigations (DSI) is the newest. These services can rack up compute charges to perform processing (in the case of DSI, AI processing of items found in Microsoft 365 sources). If tenants don’t take care, they might end up with big Azure bills. Be aware, prepare, measure, and minimize processing to avoid large charges. https://office365itpros.com/2026/02/04/dsi-costs-compute/
