Using Outlook for Android in business environments for email and scheduling
Hi @Gajendra Chouhan
Thank you for posting your question in the Microsoft Q&A forum.
Based on the information you described, I understand that you are unable to access your email and other services because you cannot use Microsoft Authenticator.
On the sign-in screen where it asks for the verification code, please look for the option “I can’t use my Microsoft Authenticator app right now” and click on it. If you previously configured SMS verification or a backup email, the system may allow you to verify your identity using one of those alternative methods.
If you no longer have access to your old phone and the alternative verification methods do not work, the best solution is to contact your company’s IT Administrator. Please ask them to reset your MFA settings, specifically to require re-registration of MFA. Once this is done, you will be prompted to set up the Microsoft Authenticator app again from scratch on your new phone the next time you sign in. Please refer the following article:

I hope this information helps resolve the issue. Please let me know if you have any updates or if you need further assistance.
