 This article explains how to configure user tags in the Microsoft Defender portal. You can also apply or remove the Priority account tag using the _VIP_ parameter on the [Set-User](/powershell/module/exchange/set-user) cmdlet in [Exchange Online PowerShell](/powershell/exchange/connect-to-exchange-online-powershell). No PowerShell cmdlets are available to manage custom user tags.
