MS Learn Unauthorized Sandbox use detected.

Copper Contributor

My account got flagged today for unauthorized Sandbox use. Odd because within the last few days I completed 2 modules using 1 sandbox environment as per the module instructions. Now I have to wait several days but I'm attending some hands on training at the Start. Dev. Change. event next week (I believe asks users to follow some of the modules which include some sandboxes)


Has anyone experienced this, why it gets flagged, and how long it took to resolve?


Seen an issue last year they addressed where large number of users were blocked and they quickly rectified this.

I have also found a GitHub issue which users are using to report this problem but no response for a while from anyone working on this. I have posted a comment as this can be a fundamental issue when events by Microsoft are using the MS Learn platform :



Yesterday i completed several learning using three sandboxes, today i receive the same message that you when i try to load a sandbox.

Yes, the same happened to my account. I was just a couple modules into the path for AZ-204 and now I'm stopped cold. I submitted the appeal and hope it is resolved soon, as I was really hoping to get into my exam prep. Between that and the Azure/O365 issues this week I'm wondering if I should still proceed with the exam.
Thanks all for flagging this. I've reported in on my end and hopefully there is a resolution soon!

Thanks for reporting this - we had a misbehaving rule in our fraud detection firewall that we think was flagging some people improperly. The team tells me it's been addressed - please let me know if this solves your access troubles!
