Currently using version 8.5.9 with PHP 7.4.33, and we’ve run into an issue with the SMTP details declining.
The error we’re getting is
5.7.139 Authentication unsuccessful, the request did not meet the criteria to be authenticated successfully. Contact your administrator. [MEWPR01CA0226.ausprd01.prod.outlook.com 2023-06-29T23:09:40.243Z 08DB78ADA0BE6197]
We’ve disabled MFA and enabled SMTP on the accounts, we can log in to the OWA using the credentials, so we know they’re valid. Has anyone come across this and know what I need to check in Azure to make sure we can log in?
