I am using javamail, O365 and it worked until I set multifactor authentication in O365. Now it has 535 5.7.3 Authentication unsuccessful Error.

How can I use Javamail when the email account has to be authoroized by phone?

You need to create an "Office 365 App Password", described for example here

It might be that it is not available to you, from above link:

Your administrator may not allow you to use app passwords. If you don't see App passwords as an option, they're not available in your organization.
