Multi-Factor Authentication (MFA) Enabled Authorization

Multi-Factor Authentication (MFA) is a security method that verifies a user’s identity by asking multiple credentials. It is a significant component of identity and access management (IAM). Unlike just asking for a username and password, MFA requires other additional credentials, such as a code from the user’s mobile phone, the answer to a security question, a fingerprint, or facial recognition.

MFA is an effective way to provide enhanced security. MFA creates multiple layers of security to increase the confidence that the user requesting access is who they claim to be.

  • Error: ‘Connecting to remote server outlook.office365.com failed with the following error message: Basic Authorization failed for user’.

    Resolution:

    In some cases, even if you use ‘app password’, authorization will fail. This may happen due to the ‘security defaults’ settings enabled. ‘Security defaults’ settings will block the legacy authentication. To overcome this, disable the ‘security defaults’ settings in your Office 365.
