Exchange Schema Versions

Active Directory

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.

Domain: [Domain Controller FQDN]
Configuration: [Domain Controller FQDN]
Schema: [Domain Controller FQDN]

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.

Schema: upperRange – This is the upperRange value of the ms-Exch-Schema-Version-Pt attribute under the Schema container.
Configuration: ObjectVersion – This is the ObjectVersion of the Organization container under the Configuration container.
Domain: ObjectVersion – This is the ObjectVersion of the Microsoft Exchange System Objects container under the Domain.
Build Number – Exchange build number.
