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.

I will :-)

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?

I ended up on this page which showed a 503 error.
https://www.website.com/P...nline/Authorize.aspx
Using a Letsncrypt certificate.
Yes

We used a workaround for now but I'll tray again in about a week.

 

 

I think I can describe how to make it work with Exchange online. It is quit simple when you know that you have to use Microsoft Graph

• In DNN
  • Personabar - Security - More - SSL Settings:
    Make sure that SLL Settings = ON
     
• In Exchange
  • Create a mailbox with al licence.
     
• In Azure
  • Create an App registration
    • Redirect URIs:

      • https://[DOMAINNAME]/Providers/SmtpOAuthProviders/ExchangeOnline/Authorize.aspx

      • https://[DOMAINNAME]

    • Secret

    • API Permissions

      • Microsoft Graph

        • Delegated -> SMTP.Send (Send emails from mailboxes using SMTP AUTH)

• In DNN

  • Servers - Seversettings - SMTP Server

    • SMTP Sever and Port = smtp.office365.com:587

    • SMTP Authentication= OAuth

    • Auth Provider = Exchange online

    • Tenant Id = [Directory (tenant) ID] 

    • Client Id = [Application (client) ID]

    • Client Secret = [client secret value]

  • Save Settings

  • Authorize

    • Using the Microsoft Mailbox credentials

  • Test SMTP Settings

Thank you Mr Needle for adding the procedure to the DNN Documentation :-)
https://docs.dnncommunity.org/content/tutorials/server/smtp-servers/set-up-oauth-microsoft-365/index.html

I have version 09.06.01 and I don't have these options

Servers - Seversettings - SMTP Server

SMTP Sever and Port = smtp.office365.com:587

SMTP Authentication= OAuth

Auth Provider = Exchange online

Tenant Id = [Directory (tenant) ID]

Client Id = [Application (client) ID]

Client Secret = [client secret value]
