Welcome to TPG Community!
Thanks for reaching out to us and we sorry to hear that you are having issues with your email.
May we know if this is happening to all email addresses that you were trying to send into? or is it just on a specific tpg email address?
Were you able to try changing your TPG email account password?
It was the solution that fixed the issue from the previous post.
If you already changed the password, but the issue persists, please post a screenshot or provide us your outgoing mail server settings for us to look into it.
I'm overseas at the moment and email sending stopped working today (receive OK). Android Phone and WIndows 10 laptop.
Happens on mobile data and WiFi.
Maybe an issue with SMTP at TPG end?
If you're using email clients/apps to receive or send emails, you will need to change your current SMTP settings. You have to use the SMTP server settings of the current ISP you're connected to.
Similarly, you can use webmail by logging in to the post office and send messages from there.
