Well ... figured out how to use Office templates ... or ... at least one way to do it; opening the template itself will create a blank document with the contents of it. Not sure why attachments isn't working, though.

@cambridgeport90 What do you mean by attachment of Office document?
Template is often blank with defined styles.
@Rado1 if you have a blank document, you should be able to apply one via the addends portion of word options. That's what I was trying to do. but I guess that's not what that's actually used for.
