I'm automatically sharing records in MS CRM 2011 on specific users and teams using custom rules. But users are able to alter this sharing information using button on MS CRM ribbon, and this will spoil all the security model I have.
I believe should be a way to prevent this information from being updated by using plugin on server side. But I'm not aware Update
event on which entity I should listen to capture this edit event?
Records in which entity are created when user shares an entity?
