Outlook not working

Hi @KerryKnight,
Welcome to the Q&A Team.

I understand you're experiencing issues with your Bigpond email address not functioning properly in Outlook. 

Please note that as a Microsoft Moderator, my ability to investigate is limited due to restricted access to your specific setup and diagnostic tools for third-party email providers. However, I’ll do my best to support you with the resources available.

To assist you more effectively, could you please provide the following details:

• Could you share a screenshot of the issue you're encountering? What troubleshooting steps have you already tried?
• You mentioned contacting Microsoft Support, may I know what was their response or analysis regarding the issue?
• Do you still able to sign in your Bigpond account on Telstra?
• Which version of Outlook are you using: New Outlook or Classic Outlook?

In the meantime, you can try to add your Bigpond account to Outlook again as a workaround.

I suggest you create a new Outlook profile and sign your account to that profile, so it do not affect to your current inbox.
