Microsoft Support Lifecycle Policy provides Microsoft Dynamics products Extended Support

Microsoft® is pleased to announce the addition of Extended Support for Microsoft Dynamics™ products under the Microsoft Support Lifecycle (MSL) policy. In the past, Microsoft Dynamics products received five years of Mainstream Support, before support ended. With the addition of Extended Support, selected Microsoft Dynamics products will receive a minimum of 10 years of support from Microsoft.

The Microsoft Support Lifecycle policy provides customers predictable support timelines to help plan their information technology environment. The policy for business and developer products, which includes selected Microsoft Dynamics products, provides a minimum of 10 years of support (5 years of Mainstream Support and 5 years of Extended Support). The Microsoft Dynamics product lines that will receive Extended Support are: Microsoft Dynamics AX, Microsoft Dynamics CRM, Microsoft Dynamics Great Plains, Microsoft Dynamics NAV, Microsoft Dynamics SL, and Microsoft Dynamics Retail Management. This policy went into effect on November 5, 2007.
