From May 4, 2026, changes ecosystem the way subscriptions within the Microsoft Cloud Solution Provider Program are treated when they are not renewed. With this change, Microsoft introduces the Extended Service Term (EST).

For organizations using cloud services such as Microsoft 365 via the CSP model, this means that they must clearly choose how to proceed when a subscription expires. The period during which services could temporarily continue to work after a subscription expired is disappearing.

The goal of this change is to better align subscriptions and license usage and to give organizations more control over their subscription management.

What changes when a CSP subscription expires?

When a CSP subscription reaches the end of its contract term, organizations must actively determine what happens to the subscription. There are three possibilities.

An organization can renew the subscription for a new contract period. Another option is to terminate the subscription on the end date, causing the services to stop immediately. The third possibility is to use the Extended Service Term, under which the services remain temporarily active while an organization decides on the next step.

This approach ensures that organizations do not unexpectedly lose access to their services, while simultaneously having clear insight into the costs of usage after the original contract period has expired.

What is the Extended Service Term (EST)?

The Extended Service Term (EST) is a temporary extension that allows organizations to continue using their cloud services after a subscription has expired. This period is intended as a bridge to give companies time to decide whether to renew or terminate their subscription.

During the Extended Service Term, usage is billed based on the standard monthly rate with a surcharge of approximately three percent. Organizations may terminate this extended period at any time. In this case, costs are calculated pro rata for the period during which the service was actually used.

The Extended Service Term is therefore not a new contract period, but a temporary solution to ensure continuity of services.

When is a subscription eligible for EST?

Not all subscriptions automatically qualify for the Extended Service Term. Microsoft has established a number of conditions for this.

The subscription must have been purchased or renewed as of April 1, 2025, and have an end date on or after May 4, 2026. Additionally, automatic renewal must be disabled, and the subscription must not have been cancelled in advance.

When these conditions are met, the subscription can transition to the Extended Service Term upon expiration so that the services remain available while the organization makes a decision regarding renewal or termination.

Why is it important to prepare for this?

This change means that organizations need to plan their CSP subscriptions better. IT administrators and license managers would be wise to determine well before a subscription end date whether they wish to renew, cancel, or temporarily make use of the Extended Service Term.

By evaluating subscriptions in a timely manner, companies can prevent unexpected costs and ensure access to important cloud services remains guaranteed.
