Is the Microsoft Office 365 Pop3 basic authentication deprecation going to have any impact for sites using Office 365 mailboxes?

Environment:

Mailboxes
Oracle B2C Service, All versions

Resolution:

Oracle B2C Service is taking a proactive approach to the announcement made by Microsoft to deprecate basic authentication for MS Exchange. We have been working since January to design and implement a solution that will keep customers that are using Exchange running after the change by Microsoft. Our design and its functionality should allow customers to implement with little effort or impact to their organization. We plan to have this work completed for the 20D (November) release of Oracle B2C Service which should give customers time to implement prior to the changes planned by Microsoft. 

Please note in response to the COVID-19 crisis, Microsoft has deferred the end of support date for basic authentication for active use customers until the second half of 2021.
