I

I hate trying to find what build number of Exchange maps to which service pack or roll up.  Every time I go through this (as it does not happen often enough for me to remember the common ones) I dig and dig and …dig… and yeah, that gets old quick.

This time through I found a great article and wanted to share it.  It is sourced from:

http://social.technet.microsoft.com/wiki/contents/articles/240.exchange-server-and-update-rollups-build-numbers.aspx

I thought I would upload a copy as well in case the link changes so here is my document (copy and paste from the site):
