You can forward your student email to a non-UQ address.

To set up email forwarding, follow these steps:

Log in to your student email. Go to Settings at the top of the page. Type 'forwarding' into the 'Search all settings' box and click the result 'Forwarding'. Click 'Start forwarding'. Enter your preferred email address under 'Forward my emails to'. Tick the box 'Keep a copy of forwarded messages'. If something goes wrong, you'll still have a copy of your messages. Click 'Save'.

You can forward your student email to another UQ address, but it is not recommended or supported.
