Get-MailboxLitigationHoldStatus

<#
.SYNOPSIS
    Reports litigation hold status across all mailboxes.

.DESCRIPTION
    Lists every mailbox with litigation hold enabled, along with the
    configured hold duration, so holds that were only meant to be
    temporary get noticed instead of silently running indefinitely.

.EXAMPLE
    .\Get-MailboxLitigationHoldStatus.ps1

.NOTES
    Requires ExchangeOnlineManagement and an active Connect-ExchangeOnline session.
