MC1323250 — [Action Required] Update scripts using Get-MailDetailTransportRuleReport and Get-MailTrafficPolicyReport

Starting July 30, 2026, Get-MailDetailTransportRuleReport and Get-MailTrafficPolicyReport will return transport rule data only when the -EventType parameter (TransportRuleHits or TransportRuleActionHits) is explicitly specified. Administrators must update related scripts and automation before this date to avoid incomplete results.
