Fortunately, a lot of users succeed in sending email using Microsoft OAuth and SMTP, like reading using IMAP.
There is no more work on Dolibarr side around this I know because when it does not work the problem seems on microsoft side only (the setup on Microsoft side is very complex for unknown reason and very bugged, it works for some, does not for other). But Microsoft does not provide any efficient support to help users to diagnose what’s wrong on their setup. It seems this is done on purpose, Microsoft don’t want external application to use their email SMTP service and prefer that you buy and use their own solution.
It is clear that using Gmail or any other sMTP provider that is not MS365 is 100% ok, when using MS365 has a lot of trouble on microsoft side, with no explanation provided by Microsoft.
When it works with MS365, it’s great, but if it does not, i’m afraid there is no real action we can do on our side to solve this…
