Quick guidance on Oauth vs SMTP for email queues

[Andrew Hatch]

I keep seeing those alerts on email queues (for me, connected to shared mailboxes in AzureAD/Exchange). I'd love to use Oauth, but wouldn't you need to consume a license ? The pop-up warning of non-Oauth connections being unstable is troubling, but is the real solution to consume a basic Office license and do a one-time authentication ?

I had a queue just mysteriously stop processing today, so fixed it up, but trying to understand the best use case here. I have MFA policies on all Azure accounts and don't want to exclude accounts from it if I can. Just struggling to get some practical guidance on the best practice going forward.
