You can use the following PowerShell script to hide the mailboxes specified in a CSV file:

First, open the Exchange Management Shell on your on-premises Exchange server.

Import the CSV file that contains the mailboxes you want to hide using the following command:

mathematicaCopy code $mailboxes = Import-Csv -Path "C:\Path\To\File.csv"

Replace "C:\Path\To\File.csv" with the actual path to your CSV file.

Next, run the following command for each mailbox to hide it from the Global Address List (GAL):

bashCopy code $mailboxes | ForEach-Object {Set-Mailbox $_.EmailAddress -HiddenFromAddressListsEnabled $true}

Replace "$_.EmailAddress" with the appropriate column name from your CSV file that contains the email addresses of the mailboxes you want to hide.

Verify that the mailboxes are hidden by running the following command:

vbnetCopy code $mailboxes | ForEach-Object {Get-Mailbox $_.EmailAddress | Select-Object Name, HiddenFromAddressListsEnabled}

This will show you a list of the mailboxes and their current hidden status.

Note that it may take some time for the changes to take effect in Office 365, so you may not see the updated GAL immediately.

Answer 1

Hi @Roger Roger,

From the error message Cannot bind argument to parameter 'Identity' because it is null, there is no value passed to the Set-RemoteMailbox cmdlet.

Since the data format in your csv file is:

users

******@contoso.com

You should modify this row from

foreach($user in $users){Set-RemoteMailbox $user.Name -HiddenFromAddressListsEnabled $true}

to

foreach($user in $users){Set-RemoteMailbox $user.users -HiddenFromAddressListsEnabled $true}

Can you post a screenshot of the csv file?

Hello @Roger Roger !

The error message indicates that the $user.Name parameter is null, which means that the Name column from the CSV file is not being read properly.

Make sure that the header name of the CSV file is "Name" and that there are no extra spaces or characters before or after the header name.

You can also modify your code to explicitly reference the "Name" column in the CSV file using the following syntax:

$users = Import-Csv C:/temp/list.csv

foreach ($user in $users) {

**Set-RemoteMailbox -Identity $user.Name -HiddenFromAddressListsEnabled $true**

}

This should ensure that the Name column is properly read and used to set the Identity parameter for the Set-RemoteMailbox cmdlet.

i hope this helps , if it did helped kindly mark it as Accepted , otherwise send us some feedback !
