Microsoft Exchange team is wrapping up the Beta version of Exchange Server 2007 SP1 and it is scheduled to be released sometime after April through TechNet. We are targeting final release for the 2nd half of this year. Our work in this Service Pack is purely in response to our customers’ feedback on earlier releases of Exchange Server 2007.
Check the article at Microsoft Exchange Team Blog website for a quick overview on some of the new features and improvements to be included in SP1
More information will be posted in the coming months. Stay tuned.
