Charts & IllustrationsImportant Dates for Forefront Products
Antigen products will leave Mainstream support soon and customers should migrate to newer versions as soon as possible. Shown here are Directions on Microsoft’s best estimates of important upcoming support dates for recent versions of the Antigen and Forefront line of antimalware products.
Microsoft itself has changed the published support dates for Antigen in the past and may do so again, likely to match the support dates for the protected products. For example, the Antigen 9.0 products for protecting Exchange and SharePoint will leave Mainstream support on the same date that Exchange Server 2003 and SharePoint Portal Server 2003 leave Extended support.
