The N-1 Partner support policy for on-premises products

MPN Partner support is for on-premises products, and they follow the N-1 support policy. The N-1 support policy enables only the newer on-premises products.

N-1 includes the current product (N) and the previous product version (N-1). Older (N-2) products and any product where Mainstream Support has ended, are not entitled for support incident creation.

Note: Product support is available from Microsoft, for the partner or customer, for products within the Microsoft support lifecycle. Online they should select the “Buy Now” option and use Pay Per Incident or an alternative support offering to create a support incident.

Product summary list

The N-1 support policy applies to all on-premises products. For the products not listed below, please see the example below for more details. The information below will change if a new product or service pack is released, when the mainstream support end date* is reached (usually after 5 years), if support dates are changed by Microsoft or if the MPN policy is changed.

Q. Does the N-1 support policy impact any other partner support related benefits? 

A. No. The policy only applies to “Partner support Gold 20pack”, “Partner support Silver 15pack” and “Partner support MAPS 10pack”. Signature support, Advanced Support for Partners and Pay Per Incident are not impacted by the N-1 Support policy.

Q. Why don’t I see the support plan displayed, under “Step 2: Tell us about the type of support you need” section, for old products?

A. When the product or version are invalid, the Support for Business workflow will not display a support offering, under “Step 2: Tell us about the type of support you need”. Therefore, you will only see the support offering eg “Partner support MAPS 10pack” for the current on-premises product (and the previous product version if within  mainstream support).

If you select a product that is no longer supported due to the n-1 policy, the support offering eg “Partner support MAPS 10pack” will be displayed under the “Would you like to see unavailable support plans?” section; with the error message “Support plan cannot be used for support on the specified product”.

Q. How can a partner obtain support for a product no longer entitled to support due to the N-1 support policy?

A. Product support is available from Microsoft, for the partner or customer, for products within the Microsoft support lifecycle. Select the “Buy Now” option online.

Q. I cannot see the option to Buy Now.


A. Due to a design limitation, Pay Per Incident is not currently available for an AAD sign-in. Pease use an MSA Sign-in eg for Pay Per Incident

Q. What is Mainstream and Extended support?

A. Mainstream Support is the first phase of the product lifecycle. For Pay Per Incident, all support options are available, including non-security updates and program / no-charge support. Mainstream Support lasts for the first 5 years. MPN product support incidents and Internal Use Rights (IUR) can only be used during the mainstream support phase. For products in Extended support Paid support should be used.
Extended is the second Support phase following Mainstream Support. Non-security updates and programs support It may last for an additional 5 years. Paid support is available for mainstream and extended support.
See KB14085 Microsoft Business, Developer and Desktop Operating Systems Policy

Q. Can I use MPN Partner support eg Partner support MAPS 10pack for Cloud products?

A. MPN Partner support is not entitled for Cloud support. Competency partners should use Signature Cloud Support for Cloud products. For Cloud Partner offerings see Compare partner support plans or for an offering similar to Pay Per Incident where you can pay online using a credit card see Azure Support Plans

Example: Applying the N-1 support policy for Microsoft Exchange Server

To identify the current and previous product versions, and the mainstream support end date, search the product life cycle

  • The current version is Exchange server 2019 (N) and the previous version is 2016 (N-1);

  • The current and previous product are both in mainstream support (usually 5 years from release date). Therefore, Exchange server 2019 and Exchange server 2016 are both entitled to support using Partner support incidents.

The older products such as Microsoft Exchange Server 2013 product are not entitled to support. Therefore, when the Microsoft Exchange Server 2013 product is selected support incidents cannot be created. See User experience using online submission below.
