Oauth2.0 Email setup for LF Forms 12

Forms

I'm having trouble getting Oauth2.0 authentication to work with LF 12 forms. I've been through the documentation and settings multiple times but I keep getting the following error

I have my redirect URIs set

Client secret is configured

API permissions are set (SMTP.Send was added after the authorize was run through the forms config page)

The Authorize is successful

The account being used as the from account has all Email apps allowed and does not have MFA enforced on it.

But the test results in the Authentication Unsuccessful message.

Any idea what I may be missing?

I just figured this out! In case it helps anyone in the future. You need to use the same sender account when logging in under the Authorize button. My login kept popping up as the domain admin account and my muscle memory always kicked in and clicked through the authentication prompt.

Logging in as the sending email account under the Authorize button completed the authorization and following that was I able to successfully test the email send.

This worked for me! Thank you for posting. The only thing I had to do was allow user consent for apps temporarily. If I would request authorization and try and approve it as an admin in Entra under Admin consent requests it still wouldn't work. I know there is a bug in 11U5 but the setting that was recommended for that still didn't work so I just had to allow user consent for 10 mins and approve it.
