Hi Ruby-N,

Thanks for your reply but as you can see from my original message, even with logged into my account I get the error message that, "Chat authentication has failed. AUTH SETUP ERROR"

This is my problem, I can't even get to the chat.

Dear @Philip Fugit,

Thank you for reaching out again and for confirming your concerns.

The message “Chat authentication has failed. AUTH SETUP ERROR” shown in the Support Assistant (Preview) pane usually indicates that the embedded chat is unable to complete the sign-in authentication process in the browser. This can be caused by preview feature limitations, blocked third-party cookies or browser extensions, or a tenant managed by a Cloud Solution Provider where direct Microsoft support is not enabled.

As a first step, I recommend opening an InPrivate or Incognito browser window. From there, please sign in again to the Microsoft 365 admin center using your admin account. Once signed in, make sure the account is fully authenticated and then check the Support Assistant pane again.

If the Support Assistant pane continues to show the same error, you may use the classic support experience as a workaround. The steps are as follows:

Step 1: Turn off Support Assistance.

Step 2: Use the search box to describe your issue. The system will display suggested solutions for common scenarios.

To help me better understand your environment and assist you more effectively, could you please confirm the following details:

1/ After turning off Support Assistance, does the error message still appear?

2/ Is your Microsoft 365 tenant provided or managed by a Cloud Solution Provider?

3/ Would you like to create a support ticket to work directly with a support agent?

4/ After trying the steps above, does the error continue to occur?

This will help us better understand the context and provide more targeted support. Any additional information will help me better understand and support you.

Thank you again for your time and cooperation. I look forward to your response so I can assist you further.

Dear @Philip Fugit,

Good day, and I appreciate the clear explanation of your concern. I truly appreciate you taking the time to share your experience.

Currently, Microsoft has introduced Support Assistance with AI chat to help address common issues more quickly and to collect feedback for service improvement.

I understand that your preference is to create a support ticket and work directly with a support agent, and the steps below will help you do exactly that.

Step 1: Turn off Support Assistance

Go to the top right corner of the page and turn off the Support Assistance button.

After turning it off, a feedback window may appear. You may share your suggestions if desired, or select Cancel to close the window.

Step 2: Access the Contact Support option

Enter your contact information carefully to ensure smooth communication.

It is recommended to note your available time for support to help the assigned agent reach you effectively.

After the ticket is created, the system will assign a support agent. The agent will contact you via phone or email, depending on the details provided in your ticket. Please keep an eye on your phone and email to avoid missing any communication.
