From your description, I understand how confusing this is when your Minecraft, Xbox, and OneDrive are all affected at the same time. Because those services all use the same Microsoft account, the first thing to clarify is where the sign‑in is failing. This will help me guide you to the correct recovery path.
Have you tried the steps in the Q&A Assist reply under your post?
To narrow this down, could you please confirm:
- When you try to sign in, are you completely blocked from signing in?
- What exactly happens on the sign‑in screen (for example, which email address it asks you to use). Do you recognize the Outlook address that appears on screen, or does it look completely unfamiliar?
- Do you still have access to any recovery method for that account, such as a phone number, or another email address?
If you are being asked to sign in to an Outlook address you don’t recognize, that usually means the Microsoft account sign‑in email (alias) was changed. In that case, access to Minecraft, Xbox, and OneDrive can’t be restored separately, they all depend on recovering the Microsoft account itself.
If you’re unable to sign in because you don’t know the password or can’t pass verification, the supported next step is to fill out Microsoft’s account recovery form:
- Go to: https://account.live.com/acsr
- Enter your original email and an alternate email where Microsoft can contact you.
- Provide as many accurate details as possible, such as old passwords, frequent contacts/subject lines and submit from a familiar device/location.
- Wait 24–72 hours for a response. You may refine and resubmit up to twice per day.
- Please see this official guide to help you fill out the form more accurately: Help with the Microsoft account recovery form - Microsoft Support
Please kindly note that this is a public user-to-user forum, I do not have the ability, tools to unblock, recover accounts or bypass security. Only Microsoft’s official recovery process can restore access.
Looking forward to your reply so I can assist you further. Thank you so much for your time and understanding.
