If the email address was changed or replaced, access to the original Microsoft account does not move automatically to a new account. A changed alias or a newly created account can make it look like devices, mail, and account data are gone because those items are tied to the original account.
Use these steps:
- Check whether this is a different account sign-in issue.
- If a screen asks Which account do you want to use?, there may be both a Personal account and a Work or school account using the same email address.
- In that case, sign in to the correct account type.
- Check the sign-in aliases on the Microsoft account that is still accessible.
- Go to Your info and edit account info, or use Manage how you sign in.
- Verify whether the old email address is still listed as an alias, whether a new alias was added, and which alias is marked as primary.
- If needed, select Make primary for the correct existing alias, or add another email address.
- If the old account used a personal Microsoft alias, review whether it was removed.
- Removing a Microsoft-domain alias such as
@outlook.com, @hotmail.com, @live.com, or @msn.com permanently deletes that alias and it cannot be associated with any Microsoft account again.
- If removing a primary alias, another primary alias must be chosen first.
- If access was lost because security info was changed, check whether the account is in a restricted state.
- If all security info was removed and replaced, the account can be restricted for 30 days while the change is pending.
- During that period, further changes to security settings may not be accepted.
- If the issue is that the original account can no longer be accessed, use the account recovery process.
- If the sign-in details are correct but the verification options are not recognized, account recovery may be required.
- If prompted during sign-in and the listed verification methods are unavailable, select I don't have any of these and follow the prompts.
- If this is only about Outlook showing the wrong account, remove the incorrect account from Outlook and sign in again with the correct one.
- In new Outlook: View > View settings or File > Account info > Accounts > Your accounts.
- In Email accounts, find the account, select Manage, then Remove.
- Warning: removing the account from Outlook deletes offline cached content for that account from the app, but it does not delete the account itself.
If the original account is recovered, devices and data associated with that original account should be available only under that account, not under a newly created one.
