Download and replace license keys every six months to continue using on-premises Dynamics 365 Business Central online.

Impacted audience

CSP partners

Effective June 5, 2026, Dynamics 365 Business Central online customers running on-premises deployments of Business Central via Dual Use Rights (DUR) license keys must download and replace their license keys every six months to continue using the on-premises product.

These license keys prevent continued use of the on-premises environment beyond the end date of the subscription’s term (when the license key was downloaded), plus a buffer period. Use of the DUR license beyond the expiration of the Business Central online subscription (such as during the buffer period) is prohibited.

Next steps

Customers may download new and replacement DUR license keys from the Microsoft 365 Admin Center (MAC).

Partners are responsible for ensuring that customer subscriptions are kept up to date and products aren't used beyond their licensed subscription terms.
