Any product that is not listed in the tables below is not supported. This is because it has not been tested, it is not compatible with Exchange Server, or it has reached the end of its lifecycle.

The following table identifies the release model that is used for updates and hotfixes for each version of Exchange Server. With Exchange 2007, each update rollup package is cumulative with regard to the whole product. Therefore, if you apply an update rollup package to Exchange 2007, you apply all the fixes that are contained in that update rollup package. This includes all the fixes that are contained in each earlier update rollup package. When we create an update or a hotfix for earlier versions of Exchange, one or more of the binary files that are included in the update or that are included in the hotfix are cumulative. That is, they are cumulative with regard to the contents of the files. They are not cumulative with regard to the whole Exchange product. The release model that is used by a product is identified by an "X."
