You've overridden <shell-escape>, bound to '!' by default, with your 
macro.  But then you are trying to use '!' inside the macro.  That's a 
loop - instead of calling <shell-escape> you are calling your macro 
inside the macro.

Try (untested):
   macro index \! "<shell-escape>/usr/bin/mbsync \$MYSYNCFOLDER\n"
