Click “Sign In” and enter your Microsoft 365 email address and password. If you're accessing it from the Outlook app, open the app, and if you're not already signed in, enter your email and password. If you use Multi-Factor Authentication (MFA), you might need to verify your login via a code sent to your phone or through the Microsoft Authenticator app or help at 1-866-719-1004. Once authenticated, you’ll have access to your Outlook inbox and other Office 365 services.
