Enable WS-Federation on OWA

Parameter | Remarks |
|---|---|
| -exchangeFQDN | the external full qualified domain name of your Exchange server, e.g. mail.acme.org |
| -dualshieldFQDN | the external full qualified domain name of your DualShield SSO server, e.g. dualshield.acme.org |
| -dualshieldPort | the external port number of your DualShield SSO server, e.g. 8074 |
| -idpCertFile | the full path file name of your DualShield IdP certificate, e.g c:\certs\dualshieldidp.crt |

Example:
Import IdP Certificate
If you have multiple Exchange servers, you do not need to run the PowerShell script "setup-owa-mfa.ps1" on all Exchange servers. You only need to run the PowerShell script on one of the Exchange server. The changes made by the PS will be automatically replicated to other Exchange servers, apart from the IdP certificate. Therefore, you do need to run the second PowerShell script "import-idp-cert.ps1" on other Exchange servers.
