I'm using external software to execute this font change (AutoHotkey).

I had some help to get this done in Microsoft Word. Here is part of the code I believe to be relevant for Office (Microsoft Word at least) :

oWord := ComObjActive("Word.Application") font := oWord.Selection.Font.Name oWord.Selection.Font.Name := "Segoe UI Symbol"

I assumed the operation would be similar in Outlook, but I'm not knowledgeable enough to know how to alter the code to make it work in Outlook. Perhaps I'm going about this all wrong?

Any help would be greatly appreciated. Cheers.
