After I activated the 'Default Security' in Office 365, the multifunctionals can't scan-to-mail .
I get error
SmtpCmdResp: 535 5.7.3 Authentication unsuccessful [LO2P265CA0457.GBRP265.PROD.OUTLOOK.COM]
SMTP authentication failed after sending password.
Check your username/password or your SMTP server's auth settings
Settings: smtp_host: smtp.office365.com
Before activating Default Security there was no problem.

Well you might have bothered to read the documentation on Security defaults first to avoid such issues :) Among other things, they block basic auth for SMTP, which I suppose is what your devices use. You can either disable Security defaults, create a similar CA policy with exceptions added for the devices, or use some smart host/relay to route those messages.

Nah, i'm more the 'let's see what this button does' type of guy :)
MS is expert in producing large quantity's of text with very little info. Especially if English is not your native language it's sometimes very difficult to follow.
Do you think there is a way to **bleep** a little hole in the default security , just to allow one mailaccount to send mail via SMTP ?

That depends on what licensing you have. Security defaults on their own don't allow much customizability, it's a plain on/off switch for all features as a single package. But if you have AAD Premium licenses, you can create a policy that matches the Security defaults restrictions, with few added exceptions as needed.

I use Kyocera devices. SMTP used to work, until I activated Default Security.
For new Office 365 tenants, Default Security is now standard set to 'on' , so new Office 365 users won't be able to send SMTP mails with multifunctional devices.
I was hoping there would be a simple way just for one user (or shared mailbox) to send SMTP mail.

@MarcVHB Right, you would need use a mailbox that has a username and password unfortunately.

I just enabled Security Defaults in our Office 365 tenant as well the other day and also have the same problem (from an app that uses SMTP). I disabled Security Defaults but the app still can't send through SMTP anymore. Even tried disabling MFA = still not working.
Did you get a resolution to your issue in the end?

No, at the moment i use the smtp server of my internet provider.
Not the way it shoud we, but it works.
