We have recently noticed that some word documents are requiring us to click to enable content. The documents themselves do not contain any code, but there is code in the template's they attach to. The locations containing the template and the document are both trusted locations (which are set through group policy).
Some documents based on the same template open without any problem, even when they are opened from the same folder as other documents which fail. After some investigation it appears that the documents that open without any problem were created using a copy of the same template located in our workgroup templates location, even though it attaches itself to the copy in the usertemplates location when it is opened. We know that Word documents store the path of the template they were created from, although this doesn't really help to explain why we are seeing this behaviour.
If I open any template directly from the usertemplate location I don't have to enable content on that template. If we remove the template from the usertemplate's location, the problematic documents attach to the same template located in the workgroup template location when opening and don't require enabling of content.
Does anyone have any insight as to why this would be happening? How is this possible when the locations are trusted? We are wondering whether an update has been applied that has caused this this behaviour to start happening as we think it's unlikely it has been behaving like this since we upgraded to Office 2010.
Thanks,
Richard
