Set-MailContact -Identity [email protected] -HiddenFromAddressListsEnabled $true
Hiding a Mail Contact from the Global Address List in Office 365
The form below will generate the correct PowerShell for you:
- Enter the email address of the contact that you would like to hide (or unhide)
- Copy the generated code into a PowerShell window.
- You will be prompted for your Office 365 Credentials.
- The contact will be changed.
Your Powershell session should look something like this:

Can you add to the list of contact addresses or do you need to duplicate the entire line
Set-MailContact -Identity [email protected] -HiddenFromAddressListsEnabled $true
for each user?

Sam,
After running the login commands:
$Cred = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $Cred -Authentication Basic -AllowRedirection
Import-PSSession $Session
to change the attribute in bulk in all mail contacts:
Get-MailContact | Set-MailContact -HiddenFromAddressListsEnabled $true
to verify changes:
Get-MailContact | select Name, Alias, HiddenFromAddressListsEnabled
