Hi @Ifeanyi Udumaga
Thank you for posting your question in the Microsoft Q&A forum.
You cannot retrieve a deleted authenticator key from Google Authenticator. Once an entry is removed, the app has no way to recover or display that secret again.
You may want to review guidance in the Google Account Community on recovering lost authentication codes: I accidentally deleted my Google Auth, - Google Account Community.

If recovery is not possible, you will need to contact your Exchange Server administrator to reset multi‑factor authentication in the configured MFA provider (for example, AD FS or a third‑party MFA solution).
