Hide a User from the Shared Address Book in Office 365

You can hide a user's contact information from the shared address book to help satisfy some of the privacy and compliance requirements of acts such as the Data Protection Act in Europe. Users can't configure this setting for their own profiles, but an administrator can use Windows PowerShell to hide a user account so the user's contact information is hidden.

Before you begin

To learn how to install and configure Windows PowerShell and connect to the service, see Use Windows PowerShell in Exchange Online.

Hide existing users from the shared address book

Run the following command:

Set-Mailbox <Identity> -HiddenFromAddressListsEnabled $true

For example, to hide the user Tamara Johnston from the shared address book, run the following command:

Set-Mailbox "Tamara Johnston" -HiddenFromAddressListsEnabled $true
Unhide users from the shared address book

Run the following command:

Set-Mailbox <Identity> -HiddenFromAddressListsEnabled $false

For example, to make the contact information visible in the shared address book for the user Tamara Johnston, run the following command:

Set-Mailbox "Tamara Johnston" -HiddenFromAddressListsEnabled $false
Hidden users in distribution groups

An Exchange Online administrator can create distribution groups that include hidden users. However, we recommend against it because, depending on the e-mail client being used, hidden users may be visible in the properties of the group.

If you want to include hidden users in public groups but are concerned about user privacy, consider using dynamic distribution groups. The membership of a dynamic distribution group is calculated every time that a message is sent to the group. This calculation is based on filters and conditions that you define. For more information, see Dynamic Distribution Groups.
