Frequently Asked Questions

Can I recreate a deleted Microsoft account using the same email address?

No. Once a Microsoft account is permanently deleted, Microsoft reserves the email address indefinitely to prevent impersonation. You cannot recreate a new account using the same email address.

Why am I still receiving emails if my Microsoft account says it doesn't exist?

Your email address might be set up as a connected inbox or an alias on a different account, or it may belong to a third-party email provider (like Gmail or Yahoo) that was merely registered as a Microsoft account login in the past.

How do I know if I'm dealing with a work or school account issue?

If your email address ends with an educational domain (like .edu) or a custom company domain, it is likely managed by an organization. In these cases, account existence errors usually mean your IT administrator has unassigned your Microsoft 365 license.
