Exchange versions and builds

This list contains the Exchange versions, build numbers and release dates for the RTM, Service packs and Cumulative Updates and rollups.
Where possible I have included a link to the Microsoft KB article and download. If a link doesn’t work anymore then it’s possible that Microsoft has removed the document or download.
