I'm trying to configure oAuth for Email using the Exchange option.
After a few config hickups we ended with the problem that apparently DNN send a non https return addres to office 365.
We do have https redirect in place but ion the end this is the error we get:

<code>AADSTS50011: The redirect URI 'http://www.website.com/Providers/SmtpOAuthProviders/ExchangeOnline/Authorize.aspx' specified in the request does not match the redirect URIs configured for the application '******************************'. Make sure the redirect URI sent in the request matches one added to your application in the Azure portal. Navigate to <a href="https://aka.ms/redirectUriMismatchError" target="_blank" rel="nofollow">https://aka.ms/redirectUriMismatchError</a> to learn more about how to fix this.</code>

Did anybody have the same issue?

I tried both the "MailKitMailProvider" and "CoreMailProvider" but the issue remained the same.

Hi Timo!
Are you testing this from host or a specific portal ?

Since it's host, the logic for https vs http for the exchange provider's redirect URL depends on the SSL settings for the host's portal. Look in the 'HostSettings' table for SettingName 'HostPortalId' (I'm not sure how that gets set since "Host Settings" disappeared with the Persona Bar?). The use the HostPortalId to lookup in PortalSettings for PortalId = HostPortalId and SettingName = SSLSetup. Make sure setting value is "1" ("On").

I did that but it crashed the "return page" :-(

What do you mean by “crashed” the page?

Ok sorry. I already forced the main site to SSL before posting this, but that lead to a 503 error when trying to complete the process, not sure why..

If you figure out all the proper setup to make it work, we would greatly benefit from having that process documented :) I could never make it work with exchange.

Is the 503 error on DNN side? Or exchange?
What type of certificate are you using for DNN? And is the DNN endpoint accessible publicly?
