Supporting custom SSO login in Add-in

[pietrofxq]

Hello, we created an add-in for outlook and we present the same Login page in the sidepanel as the one users use to login through web.

In our login page, we allow login with SSO. We have a problem in desktop outlook because outlook desktop only opens an URL inside desktop if that URL is listed in the add-in .

Since each customer that uses SSO can have a different SSO URL (for example, customer.okta.com) we are being required to manually add each customer SSO to our manifest file.

Is there a better way to handle this? This is not very scalable. We need the login flow to happen inside outlook desktop so we can save the user information. We are not sure if there is a way to handle the login outside desktop in the browser and then redirect back to the addin in outlook.

Thanks
