Extended life-cycle support for Exchange Server 5.5 originally concluded on December 31, 2005 but has been adjusted to end January 10, 2006. This adjustment is part of an effort by Microsoft to provide a more predictable and consistent end-of-life-cycle experience. Microsoft offers a minimum of 10 years support (five years mainstream support plus five years extended support).
