Microsoft 365 Developer Program instant sandbox service is restored

Kelly Bowen-McCombs (She/Her)

This week, we experienced an incident related to Microsoft 365 Developer Program instant sandboxes. New members who set up an instant sandbox were unable to sign in to their Microsoft 365 developer subscription. After setting up an instant sandbox, on sign in, members encountered the following error message.

Image Instant sandbox error message on sign in that states that the user doesn't have permission to access the resource.

This issue has now been resolved. If you set up an instant sandbox after October 1st, 2023, please reset your admin password. To reset your admin password, go to your subscription, and on the sign in screen, choose Forgot my password. Follow the steps to create a new password. Wait for 10 minutes and then sign in again. You should then be able to sign in to your Microsoft 365 developer subscription. If your sign in is unsuccessful, try resetting your admin password again.

Members who set up a configurable sandbox instead of an instant sandbox are not affected by this error.

We apologize for any inconvenience. Thank you for your interest in the Microsoft 365 Developer Program.

For general information about the Microsoft 365 Developer Program, see the Microsoft 365 Developer Program docs.

    Hello Kelly,

    Thank you for this update and information. I am having trouble getting support to understand that 2FA is enabled for the dev admin account, but was never setup/configured. I am unable to login as the admin because I don’t have a 2FA authentication app setup/configured for the dev admin account. Resetting the password is great, but until I can authenticate with a 2FA app, I am unable to login. I need assistance getting 2FA established for the dev admin account. Thus far, multiple support people have just sent me instructions to reset the password.

    Can you assist me in getting the right assistance?

    Thank You,
    Dan

    Hello, Not sure if the issue is resolved unless I am misunderstanding the error. Subscribed to the development program on Oct 8th and setup a instant sandbox. However it seems the error specified in blog post is still present for myself no matter how many password resets occur with the admin account that was created in the instant sandbox.

    I am having the same issue. Set up the sandbox on Oct 9, and have reset the password multiple times and still I get the “You don’t have access to this” message each time I try to sign in. When I try to go to https://serviceshub.microsoft.com/gethelp the site won’t let me sign in with my Microsoft account (not the one I am trying to use for the dev) it just keeps signing me out. When I looked at the page on provisioning errors is says to delete your profile, but when I clicked on that it sounds like if you do, you not can’t sign up for a subscription for 60 days. Very frustrated at this point.

    Thanks,
    Heidi

    Thank you for reporting that it’s still an issue. We’ve put in several fixes but we weren’t sure if it would fully mitigate the problem. Let me get this info to the eng team and I’ll continue to update here.

      Hi Kelly,

      I wanted to let you know that I am in! When I went to my subscription it asked me to install authenticator, and it was all good after that. 🙂

    Hi Kelly,

    I’ve also been having issues with accessing a pre-existing sandbox.

    When attempting to login with the administrator .onmicrosoft.com account The sign in page states that ” This username may be incorrect. Make sure you typed it correctly. Otherwise, contact your admin. ” a Password reset is also unavailable.

    I’ve also filled out the missing development activity form mentioning this issue.

    Any assistance in reinstating access would be much appreciated.

      There are two email addresses associated with your account.
      Use your personal or company email to sign in to the “developer dashboard” at https://developer.microsoft.com/profile. That’s your member ID. From there you can set preferences, activate your subscription, etc. If you go to that page, you should be able to verify your administrator ID on the subscription tile on the Developer Program dashboard. Maybe double check that you have the correct admin account?

      After we assign a subscription to you, we no longer have access to it – so we can’t send you a password reset or anything like that. You would have to go through the typical password reset process etc.

        Hi Kelly,

        Unfortunately the link you have provided results in a 404 error page.

        I have tried requesting the deletion of the existing account to create a new sandbox. However, The sandbox i cannot access is still listed in the account as an expired subscription.

        Thanks,

    Hi Kelly,
    My problem is the number of digit phone to receive an sms for activate my account. The system need 8 digits for CĂ´te d’Ivoire. Therefor the phones number in CĂ´te d’Ivoire are now 10 digits not 8.
    Can you do an update for 10 digits phone please for CĂ´te d’Ivoire?

    Regards
    Armand
