Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. You can easily do it using an email program or email client. That way, you have one place to send and receive emails on both accounts without messing the accounts and the emails they send and receive.
Have you tried that option already?
Please let me know by replying to me here so that I can help you further.
