I'm taking AZ-900, and following the course instruction, I'm able to activate the sandbox, but unable to sign in. Every time I click on the "Sign in" button and select my account, it takes me back to the sign in page.
The sandbox is activated because I see the below count down.

Hello, @WOLDEAMANUEL, SAMUEL !
The sandbox team is currently working on a resolution to this issue. For the time being, it appears that a vast majority of the sign-in issues are reported with outlook.com accounts. We will update you as soon as there is a resolution. Thank you for your patience!
If possible, providing a network trace will help us track down the issue faster:

Any update on the Sandbox access issue please?
I am still having the same Sandbox access problem after two months.
