             If a third party filter isn't preventing the message from reaching the user's Inbox and the first release attempt didn't work, admins can try using the [Release-QuarantineMessage](/powershell/module/exchange/release-quarantinemessage) cmdlet in [Exchange Online PowerShell](/powershell/exchange/connect-to-exchange-online-powershell) with the _Force_ switch to release the message.

           Admins can use [message trace](message-trace-defender-portal.md) to determine if a released message was delivered to the recipient's Inbox.
