To verify the AD schema has been successfully updated, check the Forest and Domain ObjectVersion and RangeUpper property in ADSI Edit.

Below Examples are for the Exchange Server SP3.

Forest ObjectVersion can be seen here: 14322

Configuration à CN=Configuration,DC=<YourDomain>,DC=com à CN=Services à CN=Microsoft Exchange à CN=<YourDomain>.

RangeUpper can be seen here: 14734

Schema à CN=Schema,CN=Configuration,DC=<YourDomain>,DC=com à CN=ms-Exch-Schema-Version-PT

Domain ObjectVersion can be seen here: 13040

Domain à DC=ds,DC=<YourDomain>,DC=com à CN=Microsoft Exchange System Objects.

$myDomain = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
$dclist = $myDomain.Forest.Domains | foreach { $_.DomainControllers }
$schemacontainer = $dclist[0] | foreach { $_.partitions | where { $_ -like"CN=schema*" }}

$ErrorActionPreference="silentlycontinue"
$dclist | foreach {
                $schemadets = "" | select name,adschemaversion,exchschemaversion
                $schemadets.name = $_.name
                $schemadets.adschemaversion = (([ADSI] "LDAP://$($_.name)/$schemacontainer").objectversion)[0]
                $schemadets.exchschemaversion = (([ADSI] "LDAP://$($_.name)/CN=ms-Exch-Schema-Version-Pt,$schemacontainer").rangeUpper)[0]              
                $schemadets}
