I'm trying to export a list of users with various attributes which have a particular attribute set to <not set>,

I've tried various combinations such as below with no luck as yet 

Get-ADUser -Filter 'extensionAttribute1 -like ""' -SearchBase 'OU=Users,DC=domain,dc=com

Can anyone point me in the right direction?

    Hi,

    Thanks for your question.

    Get-ADUser -Filter {-not(extensionAttribute1 -like "*") } -SearchBase "OU=Users,DC=domain,dc=com"

    You can try to filter the blank attribute by the script example above.

    Best regards,
