Regain Access to M365 Developer Sandbox

Copper Contributor

I have lost access to my M365 Developer Sandbox. I had set up MFA with only the Authenticator app and then changed to a new phone. Is there a way that my MFA options can be reset, or am I only left with the option of deleting my profile and waiting 60 days to recreate the sandbox?


I only had the single administrator account setup in the sandbox.

Yes, the way is reset by other admin or Microsoft support

Thanks for the response, I did mention that I only have the single global administrator account that was created with the subscription was enabled. I did contact MSFT support where I was told that I would need to seek help on community as MSFT Support did not support M365 Developer Environments.
Hi JScottPitman, have you resolved it? I had the exactly same issue.
