Error in using Exercise Sandbox while doing AZ-900 course

Question

Hi.

I got an issue while I'm doing AZ900 course.

Below is the error message:
"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."

What do I need to fix this?

Thanks.

Hi Ji-An,

You didn't mention which specific exercise you are on. The below instructions work for most, but if you have questions/issues with the one you are on please add a comment.

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 (Some exercises use 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, open Azure portal in separate browser tab, etc.

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

Thanks.
