I am trying to complete the exercise in my Microsoft Learn Learning Path, and I encountered this

"Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application

'18fbca16-2224-45f6-85b0-f7bf2b39b3f3' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account."

Meanwhile, I have already successfully signed in to the Microsoft Learn Sandbox Directory (I have attached a screenshot of this) separately, but when I try to sign in through the link provided on Microsoft Learn, I run into this error message.

What am I doing wrong? User's image

    Hi,

    This is known issue with the sandbox. You didn't mention which exercise you are working on, so below is workaround for Explore the Learn sandbox exercise. Please give instructions a try and let me know your results.

    You should be able to work around the issue by first Activating the sandbox (solving puzzles, reviewing/accepting permissions, etc.) and then once you see the sign-in box appear on the right open a new browser tab. In this new tab, browse to https://shell.azure.com. If your existing sandbox hasn't expired you can use that instead of activating a new one.

    When prompted, click Bash (The exercise uses PowerShell and Bash. You can switch between them using button at top of cloud shell window)

    Next choose No storage account required, for Subscription select Concierge Subscription, and click Apply.

    After several seconds delay while a cloud shell is requested and connected to, you should see $ prompt. At this point you can complete the exercises instructions, copy/paste code from exercise tab to cloud shell tab as needed, etc.

    Please click Accept Answer and upvote if the above was helpful.

    Thanks.
