Error updating owaecp access is denied
There is no need to activate a device for the monitoring user.
Ensure that you are installing Duo on an Exchange server that holds the Client Access Server role.
Other Exchange roles (like the Mailbox role) may also be present.
Duo's OWA application does not add two-factor authentication to the RPC endpoint.
We recommend against exposing the Outlook Anywhere endpoint to external access.
I go to https://serveraddress/ecp and I get the login page - I enter correct credentials but then get taken to a blank page - no errors. Issue occurs using the browser on exchange server or a remote PC.
Issue occurs if I use IP or FQDN in place of serveraddress in url above and same if I use 127.0.0.1 when on the exchange server itself. From my google searches I have tried: I tried this now when I log in instead of getting a bank page I get the following error: Server Error in '/ecp' Application.Per Microsoft, the OWA app for i OS does not support multifactor authentication.
