Hi there Ryan M.

I am Lumie and I would love to assist you today.

I am so sorry you are having issues with a lost account.

Please keep in mind, this is a user forum, we are not Microsoft.

The transaction ID and username cannot be used in recovery, you must use the tools provided by Microsoft.

The first idea to find your email is to directly log into your account with your phone number. You can find your username using this recovery tool: [https://account.live.com/username/recover] by inputting related data.

If this does not work, you can try to look for email receipts on alternative accounts or find accounts you made be logged into on different services.

Once you have found the new address, you can recover the account using the Account Recovery Form: https://account.live.com/acsr]

Make sure to complete it in an area you would usually access your account from. It is important to be consistent with this form, you can complete the form twice a day everyday until your regain access to your account. Repeating this will increase your odds of recovery.

Here are more tips to follow with the form: [https://support.microsoft.com/account-billing/b19c02d1-a782-dee6-93c3-dc8113b20c42]

I hope this helps!
