We have a two Optus internet accounts for different locations (one business, one home) , however in the next month we will be leaving one of these locations so want to ask about transferring our existing optusnet email addresses to the other Optus account we hold.These emails are still in daily use so it's important we try to hold them, and preferably transfer them to the home account that will continue as soon as possible.
Can someone assist to provide how to do this?
Its probably possible.
You could also just set up a free GMail account. There's options to import all emails from another address so you could do this very easily. Good to have a backup I'd imagine. You can do this anytime without affecting your current Optus accounts.
FWIW I'd always recommend using a non ISP email address as you will lose it if you ever want to leave. Its not hard to transition to a free GMail account over time for example and you get a lot of benefits including security (2FA), Multiple accounts under one login, better spam handling etc.
