Powershell to change email suffix of AD Contacts whose suffix is abc.com to xyz.com in a particular OU

Question

I have the below code:
$LocalUsers = Get-ADObject -Filter {(objectClass -eq "contact") -and (mail -like '*gmail.com')} -SearchBase "OU=T,OU=Test,DC=contoso,DC=com" -Properties mail -ResultSetSize $null
$LocalUsers | foreach {$newUpn = $.email.Replace("gmail.com","contoso.com"); $ | Set-ADObject -mail $newUpn}

And get the below error:
Method invocation failed because [Microsoft.ActiveDirectory.Management.ADPropertyValueCollection] does not contain a method named 'Replace'.
At line:2 char:24

• ... | foreach {$newUpn = $_.email.Replace("gmail.com","contoso.com"); ...
• ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
• CategoryInfo : InvalidOperation: (:) [], RuntimeException

• ~~~~~
• CategoryInfo : InvalidArgument: (:) [Set-ADObject], ParameterBindingException
• FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.ActiveDirectory.Management.Commands.SetADObject

Thank you for your help!

Hi,

For the first error, the property is "mail", not "email".
For the second error, the Set-ADObject cmdlet has no "-mail" parameter. Please use "-replace" to set the mail attribute.

$LocalUsers = Get-ADObject -Filter {(objectClass -eq "contact") -and (mail -like '*gmail.com')} -SearchBase "OU=T,OU=Test,DC=contoso,DC=com" -Properties mail -ResultSetSize $null  
$LocalUsers | foreach {$newUpn = $_.mail.Replace("gmail.com","contoso.com"); $_ | Set-ADObject -Replace @{mail=$newUpn} }
