15.Enter your integration key, secret key, and API hostname when prompted.

If you leave the “Bypass Duo authentication when offline” box in the Duo installer checked, then your users will be able to logon without completing two-factor authentication if the Duo Security cloud service is unreachable. If that box is unchecked then all OWA login attempts will be denied if there is a problem contacting the Duo service.

Duo for OWA sends a user’s Windows sAMAccountName to Duo’s service by default. To send the userPrincipalName to Duo instead, check the Send username to Duo in UPN format box. For this to work, OWA and ECP must be using Forms-Based Authentication (FBA).

If you enable the UPN username format option, you must also change the properties of your OWA application in the Duo Admin Panel to change the “Username normalization” setting to None. Otherwise, Duo drops the domain suffix from the username sent from OWA to our service, which may cause user mismatches or duplicate enrollment.
