Recent windows or office updates breaking EV search button functionality in Outlook (October 12)

It seems that some Outlook or Windows updates broke the Search Button functionality in Outlook. We already do have 3 confirmation from different affected systems. Verified with EV 10.0.3/4, EV 11.0.1 CHF5 as well as 12.2.1.

Pressing the buttons does nothing. All are showing the following error (or a slightly different) when trying to open search in Outlook:

12/10/2017 13:41:16.930[7068][M]: Launching EV web application in Outlook: http://evserver/EnterpriseVault/search/shell.aspx?server=Exchange&mbx=SMTP:T.Test@Test.local&vaultid=VID&NAV=0
....
12/10/2017 13:41:17.052[7068][L]: ~LaunchURLUsingHiddenFolder::GoToURL: 0xBBC04005
....
12/10/2017 13:41:17.054[7068][H]: Action: Failed to execute action 'SEARCH'
12/10/2017 13:41:17.055[7068][H]: Action: A COM error exception has been caught: bbc04005

Opening Search in IE is working fine. We are currently trying to bring this down to a specific update. Appreciate any feedback on this. Will update when we do have new findings.

Edit 1:

It seems that the updates broke the homepage on folders feature which EV uses to open the search. Every affected system is missing the homepage button when opening folder details in Outlook.

Edit 2:

Thanks to a customer we now have the information that the problematic update seems to be KB4011196. For now we do only have confirmation for Outlook 2010.
