ICT Office【Important】Discontinuation of Basic Authentication for Sophia
Mail Use
1. Introduction

Sophia Mail uses Microsoft365, but it has been announced that Microsoft365 will
eliminate basic authentication to improve security from October 1, 2022. (*1) As a result, if
you are using e-mail software that uses basic authentication after October 1, you will nolonger be able to send and receive e-mail, so you will need to take separate action.
Instead, advanced authentication (OAuth authentication (*2)) will be introduced. OAuth
authentication is already enabled on Sophia Mail, so if you need to change your settings,
please do so by October 1.

2. Necessity of correspondence

Depending on how you read your email on your device, you may need to take action. No
action is required in the following cases.
(1) When using Sophia Mail via a browser
If you click "Microsoft365 Teachers Login/Students Login" from the ICT Office website
or set it as your bookmark (favorite).
(2) If you have set up Outlook 2016 or later on your PC or Outlook application on yoursmartphone with an Exchange connection according to the University's manual.
※If you are using Outlook 2013 or earlier, or POP/IMAP, you will need to take action.
If you are using Sophia Mail in other ways than above, you need to change the settings forsending/receiving emails using OAuth. Please refer to the examples in the table on the nextpage.
