I am not able to add a Teams account to my iPhone

Hi Shubho,

Your work account is managed through your organization’s administrator account. Although you may not have a dedicated IT administrator, you should contact your help desk or manager to determine who is responsible for managing employee accounts within your organization.

You can specifically ask whether they can:

• Reset your MFA settings
• Require MFA re-registration
• Remove your existing Authenticator registration so you can set it up again

You may also want to share the following Microsoft article with them: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | …

If you are unsure who your administrator is, you can refer to this official Microsoft guide for assistance: How do I find my Microsoft 365 admin? - Microsoft Support   

Once your administrator resets your MFA registration, you should be able to sign in again and go through the Microsoft Authenticator setup process from the beginning, including scanning a new QR code on your device.

I hope this points you in the right direction. If you receive any updates from your IT team or run into any issues along the way, feel free to reply back with more details and I'll be happy to help further.
