Unless your colleagues configure their Word installations to allow trusted access to the VBA project model - something that is dangerous to have as a default state - your scheme won't work.

Instead, if your updating code that belongs in a template they're to use, simply roll out the new template, preferably by having the users concerned joined to a group whose group templates folder is one you can update. That way, they don't have to do anything.
