Dynamics 365 and Power Platform– Information about storage validation for Dataverse-only tenants

Beginning November 9, 2026, we are introducing staged storage validation for supported Dynamics 365 applications. The change gives administrators clearer visibility into storage use, advance notice of potential restrictions, and several ways to remain within capacity, including removing unneeded data, adding capacity, or enabling pay-as-you-go for sandbox environments. When a tenant exceeds its entitled Database, File, or Log capacity, environment creation, copy, restore, and recover operations will be restricted immediately. If the overage remains unresolved, sandbox environments that do not have pay-as-you-go billing enabled will enter Administration mode after 30 days of remaining over capacity, allowing access only to administrators. After 60 days, those sandbox environments will be disabled, preventing access for all users. Production environments are not subject to these restrictions and will remain accessible. However, environment creation, copy, restore, and recover operations will still be blocked while the tenant remains over capacity. Deployment Timeline: Rollout begins: November 9, 2026 Rollout completion: December 4, 2026 How does this affect me? The Dataverse storage validation applies only to Dataverse-only tenants without Dynamics 365 Finance and Operations environment(s) or consumption. The products in-scope of storage validation include: Microsoft Dynamics 365 Sales Microsoft Dynamics 365 Customer Service Microsoft Dynamics 365 Field Service Microsoft Dynamics 365 Customer Insights Microsoft Dynamics 365 Customer Voice Microsoft Dynamics 365 Contact Center Microsoft Dynamics 365 Project Operations (Dataverse deployments) Stage Timing Impact 1. Restricted When the tenant first exceeds its entitled storage capacity, known as time zero (T0) Environment creation, copy, restore, and recover operations are blocked 2. Administration mode 30 days after the tenant first exceeds capacity – T0 Only administrators can sign in to *affected sandbox environments. All other users are blocked from accessing the environment. 3. Disabled After 60 unresolved days from T0 All users, including administrators, are blocked from *affected sandbox environments; the environment data is retained and remains available for recovery after remediation Sandbox environments with active pay-as-you-go billing do not progress through the storage overage lifecycle. Other *affected sandbox environments in the tenant may still be affected with restrictions. We will provide notifications that include the tenant’s current storage status, the […]
