Get-ADUser samaccountname -Properties msExchHomeServerName, homemdb |Select-Object msExchHomeServerName, homemdb |Format-List


2. active directory computer type objects contain "exchange" word in servicePrincipalName attribute; you can use only your organizational unit that contain your servers if you have one to narrow your search:

Get-ADComputer -Filter * -SearchBase 'OU= SERVERS, DC=domain_name,DC=net' -Properties * | Where-Object {$_.serviceprincipalname -like '*exchange*'} |select-object  name


3. active directory configuration partition contain information about exchange servers in domain; you can search for objects of class msExchExchangeServer:

Get-ADObject -LDAPFilter "(objectClass=msExchExchangeServer)" –SearchBase "CN=Configuration,DC=domainname,DC=net" | Select-Object  name


or you can list all objects from "CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=INTERNAL,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domainname,DC=net" using powershell or ADSI Edit console;

Get-ADObject -Filter * -SearchBase "CN=Servers,CN=First Administrative Group,CN=Administrative Groups,CN=INTERNAL,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domainname,DC=net" -SearchScope onelevel
