sent invoices have wrong reply-to address

I am using AccountEdge Pro on a Mac. Sent invoices have my personal repy-to email address instead of the  one defined in Company.

How do I change the the return address to not use my Mac personal account.

Not using Outlook. I am using Regular Mac mail.

I cannot change the personal Mac settings to my company one. Its not convenient to do so.

Can I redirect to a separatly installed client just for his pupose. How do I do so ?

Thanks.
