The domain for this account is ihmc.org not ihmc.us, so your email address will look like firstname.lastname@example.org. If you previously had an @ihmc.us account, emails sent to @ihmc.us will still be received at your @ihmc.org email account.
The password used for this account will be the same as other ihmc Active Directory services such as the internal website, VPN, etc.
Instructions for initial login/setup for your account
Go to outlook.office.com
Log in with your @ihmc.org email address.
A “More information required” message will appear. Click Next.
Office 365 is using two factor authentication. There are multiple options: Microsoft Authenticator (app), 1Password, Phone, or Email. To select another option than Microsoft Authenticator, click either “I want to use a different authenticator app” (1Password) or “I want to set up a different method” (Phone or Email).
Once you have set up two factor authentication, you can proceed to your account.
