Update went smoothly yesterday, on two servers in a DAG.

 

I've got an issue in Outlook Web Access with 2016 CU19 now though, where instead of previewing PDF attachments, it will download them and just show a spinning blue circle of dots in the preview pane. Previews of Excel and Word documents are working well and rendering through our Office Online server.

PS. benoitrando. Check versions at the bottom of this webpage, which have already been updated: https://eightwone.com/references/schema-versions/

I've just checked 2016 CU19, and my versions match:-
