Hello, I am using Exchange 2007 I would like to deactivate users that belong to a specific OU. I thought about that below shell command: get-mailbox -resultsize unlimited |%{if ($_.organizationalunit -eq "company.com/company/Old/Users" -or $_.organizationalunit -eq "uk.company.com/Main/Commun/Old Users") | Set-Mailbox Disable-Mailbox But I am really not sure about the "| Set-Mailbox Disable-Mailbox" and I have not test environnement. could you please tell me if that command would work or help me out to make it work? Thanks, Graig

Hi, Try this command, I think it should work for you: Get-Mailbox -Resultsize Unlimited | Where {$_.OrganizationalUnit -eq "<OUPath>" -or $_.OrganizationalUnit -eq "<OUPath2>"} | Disable-Mailbox In you case it should look something like this: Get-Mailbox -Resultsize Unlimited | Where {$_.OrganizationalUnit -eq "company.com/company/Old/Users" -or $_.OrganizationalUnit -eq "uk.company.com/Main/Commun/Old Users"} | Disable-MailboxMartin Sundstrm | Microsoft Certified Trainer | MCITP: Enterprise Messaging Administrator | http://msundis.wordpress.com

Thanks Martin! For "VIP" users I would need to add an exeption and keep their account activated. Would you please tell me how I could from a txt file NOT deactivated vip users belonging to the OU old/users ?? Graig

Hi Graig, Suggest you add one property value to the VIP mailbox users. For Example: CustomAttribute1 ->VIP The filter can be: {$_.OrganizationalUnit -eq "company.com/company/Old/Users" -or $_.OrganizationalUnit -eq "uk.company.com/Main/Commun/Old Users" -and $_.CustomAttribute1 -ne "VIP"} This is easier than write a script to import value from txt file, but you have to add the value manaully.Frank Wang
