Please I need help to regain access to my developer tenant. I mistakenly changed the admin from [Moderator note: personal info removed].com to [Moderator note: personal info removed].ng and now I can’t use any of them.

From there, you can right‑click to open your E5 sandbox and select Copy link. Next, open a new InPrivate browsing session by pressing Ctrl + Shift + N, then paste the copied link into the address bar.

    Please take note of the account shown after the login hint, as this should be the admin account of your E5 Developer tenant. After that, press Enter. If the account has been identified correctly, you should see the prompt to enter your password.

    If you are still unable to sign in after following these steps, the only available way to regain access would be to contact Microsoft Support. Consider contacting Microsoft Support via phone or creating a new trial tenant and submitting a support request on behalf of the locked tenant. Please refer to the following thread for detailed guidance: https://dori-uw-1.kuma-moon.com/en-us/answers/questions/5823773/urgent-locked-out-of-microsoft-365-developer-tenan

    Please note that the trial subscription is valid for 30 days. Before it expires, remember to cancel the trial in the Microsoft 365 Admin Center to avoid any unexpected charges. You can follow this guide for instructions: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn.

    I hope this information is helpful. Please feel free to share any updates.
