How to Hide O365 mail contact from GAL using CSV list and powershell

tried below but is looking for identity

Import-Csv c:\csv\disable.csv|%{Set-MailContact -Name $_.Name -HiddenFromAddressListsEnabled $true}

That's because you are using the -Name parameter, which is to change the Name attribute of the user, not to designate him as a subject to the Set-MailContact cmdlet. Use this instead:

Import-Csv c:\csv\disable.csv|%{Set-MailContact -Identity $_.Name -HiddenFromAddressListsEnabled $true}

And make sure you have a column "Name" in the CSV file.
