Google OAuth Problems for SMTP in Jamf Pro

[BrandonAmos]

After Google announced they would not be allowing basic credentials for SMTP, we are struggling to get the Google OAuth to work. We have followed the steps below and still not have had any luck. It keeps giving us this error but we have tried multiple URLs for the failover and it is not working. Any suggestions?

I presented on configuring Jamf Pro SMTP server settings for OAuth with both Microsoft and Google at last month's University of Utah MacAdmins meeting. You might find it useful.

The redirect URL you want to use is the one you'd see when viewing your own Jamf Pro server's SMTP server settings. For example: "https://talkingmoose.jamfcloud.com/view/settings/system-settings/smtp-server".
