Office 365 Install

Unfortunately, since Office 365 subscriptions are tied to the Microsoft account used during purchase, we won’t be able to recover or transfer the license without identifying that original account. However, here are the steps you can take to recover access or reinstall Office:

Try to recover your Microsoft account:

Go to https://account.live.com/password/reset

 and follow the steps to recover your old email address.

If you no longer have access to that email, click “I don’t have any of these” during the process and complete the account recovery form with as much information as possible (old passwords, billing info, etc.).

Microsoft Support will review it and attempt to verify your ownership.

Check for another account:

Visit https://account.microsoft.com/services

 and sign in with any possible email addresses you might have used. Your Office subscription will show under Services & subscriptions if found.

If recovery fails:

You can contact Microsoft 365 billing and subscription support.

They can help confirm ownership via your payment details (credit card or bank information) and advise on restoring access or setting up a new subscription.

Installing Office on a new device:

Once you regain access to your Microsoft account, you can reinstall Office by signing in at https://portal.office.com

 → Install Office.

If you can share the last 4 digits of the payment card used for the subscription or an approximate purchase date, support may be able to locate the subscription faster.
