Have been using this fix over the past 5 years or so, however, doesn't seem to work for Catalina. Anyone know how to fix this same issue in latest MacOS X Catalina? Impossible to change default mail client from Mail to Outlook: just jumps straight back to Mail immediately.
UPDATE: seems a computer restart is required after applying fix in Catalina: at least worked on one example: will update this after further testing.
