Your description suggests your users have their macro security set too high and/or the file is not being saved to a trusted location. Macro security setting in Word 2007 & later are essentially the same as for previous versions. Your users should go to Word Options>Trust Centre>Macro Settings and set the security level to the 2nd option (disable all with notification). That means they'll be asked whether to allow macros in a document to run. If you store the file in a trusted location, the macros will be available without that prompt.
