I cannot receive or send emails through Thunderbird.

Hi @Molly , have you tried to remove and set up your email again?

Please make sure that all settings are correct. You can refer to this link: https://www.tpg.com.au/support/emailsetting.php

Hi Molly.

Have you upgraded Thunderbird which then stopped working?

If so, have a look here:

Also, deleting your account in Thunderbird might delete your saved emails. Unless you can back them up.
