When I pull down File > Share > Send Document, Word gives a "donk" (error) sound. Same thing for File > Share > Send PDF. When I do File > Share > Send HTML, the system opens Outlook and appears to prepare an email message to send the file.
By the way, Outlook is not my default email program. A different email program (Spark) is designated for my Mac, using the prescribed but odd way to do that: open the Mac Mail app, and pull down preferences (for Mail), and in the General tab specify the default email reader.
