Microsoft have made two changes to storage capacity for the Business Apps from December 2025. Firstly, there are increases in the default Dataverse Database capacities for Power Platform and Dynamics 365 products – 10 GB for Power Platform, and 20 GB for Dynamics 365. And secondly, there’s simplification for the storage capacity used by the ERP apps. Historically, there have been separate Dataverse and Operations capacity entitlements which were capped separately. Now, the entitlements are pooled, and the storage capacity can be used for either Dataverse or Operations.
