Exchange schema version numbers

Whilst on the subject of schema versions I thought I would also include the Exchange schema version numbers


You can check the version with one of the following methods.

  • dsquery: dsquery * CN=ms-Exch-Schema-Version-Pt,cn=schema,cn=configuration,dc=domain,dc=local -scope base -attr  rangeUpper
  • ADSIEdit: open ADSIEdit and navigate to “CN=ms-Exch-Schema-Version-Pt,CN=Schema,CN=Configuration,DC=domain,DC=local”, right-click “Properties” and locate “rangeUpper” attribute value
