FermiMail: Webmail via web browser (OWA)

Intended for:

Users who want to access their Fermilab email account via web browser.

Scenario/Use case:

This article provides instructions on how to access your Fermilab email account via web browser. 


  1. Navigate your web browser to
  2. Login with your Services account, password, and then click Sign On.

  3. For this step, there are two paths that may be presented to you:
    • Yubikey - If you have a Yubikey and it is plugged into your computer, you will be presented with a prompt to select your Yubikey certificate. Select the "FERMI Sub CA" certificate and click "OK". You then be presented with the Smart Card window where you enter your Yubikey PIN and click "OK". NOTE: If you do not want to use your Yubikey, click "Cancel" and you will be guided through the RSA process below.

    • RSA - If you do not want to use your Yubikey or do not have a Yubikey, you will be prompted to provide an RSA passcode as part of the "Two-Factor Authentication" requirement. Enter your passcode and click "OK". If you are unsure how to generate your passcode, please review "How to use RSA hardware token to generate a passcode" or "How to install and use RSA soft token to generate a passcode".

  4. Upon successful authentication you will be redirected to the Office 365 Outlook Web Application.
