This thread is three years old and the feature remains unchanged. What about your customers who use MS Exchange, why only Gmail customer can change their outgoing email address?

I am a recent new user of QB however come from a software development background and I am shocked how your Dev Ops team are unable to deliver this simple feature to the mass of your customers.

Please dont reply with the same excuses and dont tell me you cant give a time this will be enabled, just deliver what your customers want.
