Exchange issues after Windows update

We've been seeing email about Microsoft Exchange experiencing growing email queues, port exhaustion, broken OWA etc, after performing the October 2026 Windows update.  This is a know issue and Microsoft is investigating.  More info is available here:  https://techcommunity.microsoft.com/blog/exchange/released-october-2026-exchange-server-security-updates/4563014
