Microsoft Replaces Free CSP Grace Period with Paid Continuation

Updated: 14 June 2026

From 4 May 2026, Microsoft replaced the free grace period for CSP subscriptions with a paid Extended Service Term (EST). If you have auto-renewal disabled, your subscription automatically continues at roughly a 23% premium instead of entering a free 30-day buffer.

This is both a price increase and an improvement. You lose the free buffer, but you gain protection against service interruption when renewals slip.

How It Used to Work (Before May 2026)

When a CSP subscription expires with auto-renewal disabled, customers receive a free grace period (typically 30 days) during which services continue working. This buffer allows time to sort out renewals, complete approvals, or resolve payment issues.

After the grace period ends, services stop. Microsoft keeps your data for up to 90 days, then deletes it. Miss that window and it's gone.

The risk: procurement delays, approvals stuck in committee, someone on holiday, or simply forgetting can push you past the grace period into service interruption.

What Changed

The free grace period was replaced with automatic paid continuation.

To actually stop paying, you must explicitly set the subscription to cancel at the end of the term. Turning off auto-renewal no longer stops billing. It moves you to EST.

The default is now the opposite. Previously, auto-renew off meant “stop after the grace period.” Now it means “continue at the premium rate.”

Microsoft announced this change on 14 October 2025, with full enforcement from 4 May 2026.

The Trade-Off

What you lose: Free 30-day buffer after expiration.

What you gain: Services keep running while you sort out the renewal. Nobody loses data because finance took too long.

The 23% premium is insurance against delays. Procurement delays happen, approvals get stuck, and sometimes people go on holiday, forgetting to take care of routine things that aren't on top of their minds. Previously, that meant a hard deadline: miss it and services stop, data gets deleted. Now you pay the premium and keep running while sorting things out.

For enterprises where service interruption or data loss would be catastrophic, 23% for a month or two is nothing compared to the alternative.

The Maths

Microsoft’s EST documentation states EST is charged at “the current monthly term rate plus a 3% uplift (or 23% if no monthly plan exists).”

CSP subscriptions come in several pricing tiers:

EST pricing works as follows:

• For products with a monthly plan available: EST = monthly rate + 3%. Monthly rate is base + 20%, so EST is roughly base + 23.6%.

• For products without a monthly plan: EST = base + 23%.

Microsoft confirmed the two rates are separate: monthly term rate + 3% for products with a monthly plan, flat 23% for products without one. The 23% roughly matches 20% + 3%.

Cost Impact by Subscription Type

Using $100 as a base price example. For products with a monthly plan, EST is monthly rate + 3%. For products without, it's base + 23%.

Microsoft 365 E5 Example

M365 E5 base price is $57/user/month (until July 2026 when it increases to $60).

Current pricing tiers:

EST pricing (monthly rate + 3%):

For an organisation with 10,000 M365 E5 users on annual billing, slipping into EST costs an extra $134,500 per month compared to renewing on time.

Which Subscriptions Are Affected

Subscriptions automatically enter EST at expiration if all these conditions are met:

1. Purchased or renewed between 1 April 2025 and 4 May 2026

2. The term-end date is after 4 May 2026

3. Auto-renew is set to off

By 16 February 2026, Microsoft converted eligible subscriptions with auto-renew off to the new EST behaviour. Since then, turning off auto-renew no longer stops your subscription. It moves you to EST unless you explicitly cancel.

Your Options

1. Understand the new default. Auto-renew off no longer means “stop at term end.” It means “move to EST at roughly 23% premium.” If you want services to stop, you must explicitly cancel.

2. Decide: auto-renew, EST, or cancel.

Three real options:

• Enable auto-renew to continue at normal rates

• Leave auto-renew off and accept EST as your safety net (roughly 23% premium, but no service interruption risk)

• Explicitly set cancel at term end if you genuinely want to stop

3. Adjust renewal processes. If your organisation habitually turns off auto-renew to manage renewals manually, that workflow now costs you roughly 123% of the normal price. Either switch to keeping auto-renew on, or budget for potential EST charges when renewals slip.

4. Consider EST as intentional insurance. For critical services where interruption is unacceptable, leaving auto-renew off and accepting EST may be a reasonable strategy. You pay more, but you are protected against timing mistakes.

Timeline

CSP subscription management gets more complex every year. EST adds another variable to track, and the consequences of getting it wrong are either unexpected bills or service interruption.
