UPDATE: Microsoft has now come clean on this update and stated that this is an intended result for security purposes. See Microsoft Breaks Custom Forms in Outlook on Purpose for Security Sake, Supplies Workaround
Customers are reporting that the security update for Outlook 2010 (KB4011089) breaks the custom forms print control.
Microsoft has yet to confirm the introduced problem as reports have only started to roll in, but customers have also reported that removing the update brings back full functionality.
Stay tuned, Microsoft customers have had a rocky go the last few months. And, it can’t be a pleasant time for Microsoft, either, having to go back and solve issues it missed the first time.
