Microsoft to retire Exchange Server 5.5 by year's end
Elizabeth Montalbano writes in NetworkWorld:
Microsoft will be retiring Exchange Server 5.5 and support for the product at the end of the year and is recommending users upgrade to the latest version, the company said Wednesday.
Microsoft is urging customers who are still running Exchange 5.5 to upgrade to Exchange Server 2003, a more secure version of the company's messaging and collaboration server product. Information about upgrading to Exchange Server 2003 can be found here .
According to Microsoft, the number of Exchange Server 5.5 users dropped by about 40% over the past year, evidence that customers have been upgrading in anticipation of the product phase-out.
Microsoft also reminded customers Wednesday that Exchange Server 2000 will move out of mainstream support into extended support at the end of 2005. Mainstream support includes free incident support, security updates and nonsecurity hotfixes. Once Exchange Server 2000 moves into extended support, customers will have to pay for support and nonsecurity related hot fixes, according to Microsoft.
