What is OWA?

Outlook Web Access (OWA) is the browser-based counterpart to the on-premises email and task management application, Microsoft Outlook. With the solution providing enterprise users access to their OWA email, calendars, tasks, and contacts from Microsoft Exchange directly from their web browsers, securing logins to OWA is vital. The existing username and password-based authentication process is not considered secure enough by many IT security experts. Unauthorized access to a user's OWA interface risks the exposure of sensitive business information and confidential email correspondence between users.

Secure OWA logins with ADSelfService Plus

An effective solution is to supplement the logins with further authentication levels through 2FA or MFA. ManageEngine's ADSelfService Plus provides MFA and 2FA for OWA and Exchange admin center (EAC) logins by implementing additional authentication steps in addition to the default username and password. This means that even if a user's credentials are misused, the enforced MFA process prevents the user account from being compromised. Unlike other solutions, ADSelfService Plus does not provide just 2FA, but also includes options to enable a maximum of three additional authentication factors. MFA is achieved through various authentication methods including the phishing-resistant and passwordless FIDO2 authentication, and biometric authentication.

How does MFA for OWA logins work?

To configure MFA for OWA and EAC logins, the ADSelfService Plus' OWA connector must be installed in the Exchange server. The connecter acts as the intermediary between the Exchange server and ADSelfService Plus to enable MFA during OWA and EAC logins. Once these requirements are fulfilled, the process shown below takes place:

  1. The user attempts to login to OWA or the EAC.
  2. The user is asked to complete the primary authentication in OWA application.
  3. If this is successful, the OWA application passes a request to the ADSelfService Plus connector which informs ADSelfService Plus to proceed with the authentication factors.
  4. If the user completes all the required authentication factors successfully, they are logged in to OWA or the EAC.

MFA for OWA and EAC logins can be configured for the following Exchange versions:

  • Exchange Server 2019
  • Exchange Server 2016
  • Exchange Server 2013
  • Exchange Server 2012

For the detailed configuration steps, refer to the MFA for OWA login help document.
