Details:

Data Lifecycle Management (DLM) billing will be based on the volume of data retained. For example, any number of non‑Microsoft 365 generative AI prompts and responses that collectively amount to 1 GB of retained data will be billed at $0.25 per GB per month (equivalent to ~$0.0082 per GB per day). In the updated model, DLM is billed based on the total volume of text messages managed by a DLM policy. Each non‑Microsoft 365 generative AI prompt and response is treated as an individual text message and is retained and deleted according to the configured Microsoft Purview retention settings. Billing is calculated on the managed text messages in storage, at a rate equivalent to $6 per one million text messages per month. Customer impact Customers will need to migrate from the legacy meter to the new meter. Based on current analysis, the overall cost impact is expected to be cost‑neutral or lower for customers under the new billing model.
