Word Invoice Merge Failed with Error "Cannot Execute MSWord Macro"

QUESTION: We are unable to complete a specific Word Invoice Merge; it is consistently failing with the error message “Cannot Execute MSWord Macro”

RESPONSE: Once you have established that the merge failure is both repeatable and not limited to a specific invoice template, the next step would be to look for strange character(s) included within entry descriptions and/or Matter information that would appear on the invoice, and remove/replace with a more standard character. It’s difficult to provide a comprehensive list, however a basic definition would be any character that you cannot identity by name or not represented by a button on a standard keyboard.
