Hi MeaganG2
It looks like you're trying to change your old email address to one that's already been used on our system or by another user. This is usually what triggers the error you're seeing. To fix this, you'll need to use a new email address that's not been registered with us before. You can make this change yourself on my.MYOB or through My Account. If you need a hand with this, our virtual assistant, MOCA, is ready to help on our website. And don't worry, if MOCA can't sort it out, you'll be seamlessly transferred to our live chat team for further support.
Cheers,
Princess
