Use the Below power shell Code in PS1 to check schema on all the servers via a script.

$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}
