This is an article I first published a couple of years ago to check what schema version a customer was running when performing an Exchange upgrade. There have since been official articles published by Microsoft, but I prefer to keep my own blog post for easy access.
This article outlines how to find the Exchange schema and version in of your Exchange schemas. There is also a list of the schema versions per build type.
To find the attributes listed below use Adsiedit.msc. When you launch asdiedit.msc there are 3 containers listed.
It can be somewhat confusing to determine what version of the schema is running when using ADSIEdit.msc. Throughout various parts of the Active Directory preparation steps the values below will change. The chart is broken into 4 columns.
