A user has asked me if it would be possible to lock a document library at a specific time and possible on a schedule.
The puropse is to ask members of the site to submit a report by 4pm on a Friday, but at 4:01pm the library goes into read only mode.
If they haven't submitted the report, then there's trouble.
I've seen that you can acheive this via IRM, but that requires a fair bit of effort to setup, and is site wide.
Does anyone have any ideas how this might be acheived using just SharePoint 2013 out of the box?
