Exchange Online Kiosk and basic authentication
We have part of users using "The Exchange Online Kiosk" License and they all are using Microsoft Outlook 2013 / 2016 Email program with POP protocol. Just to save cost for subscribe fee. And this Kiosk license will be expired next year 2023.
Q1. Microsoft will begin disabling Basic authentication after October 1, 2022, can we turn back on Basic authentication after disabled? Then we may upgrade Exchange Online Kiosk to Online Plan 1 license for these users and change to use exchange protocol instead on POP protocol next year.
Q2. POP uses couldn’t access email server last month (July-2022). And didn’t know what happen that time. So just turn off modern authentication that time. After a period, pop user can access Email server again. But make all exchange user to re-enter password once.
See that Org Settings > Modern authentication. Can allow basic authentication after turn on Modern authentication? Won't affect POP connection?
Q3. Though knowing that POP user can configure to use MS Graphic API or Thunderbird which supports OAuth2 authentication, it’s too complex. Is it better to upgrade Exchange Online Kiosk to Exchange online plan 1 and use exchange protocol ASAP? Seems not much users to use Online Kiosk license.
Q4. If use exchange protocol with Modern authentication turning on, don't need to force to use MFA again. Right?
Thank you.
