Request to check the authentication settings of your email applications

Please read this notice thoroughly, check the authentication settings of your email applications, and reconfigure them by June 22 if necessary. If you continue to use it without confirmation, your sign-in may fail and you may be unable to send or receive email messages at all.

We have notified users who might be affected by email, but due to the limitation of the usage history, we could not extract only the users who signed in with the email address. For this reason, we have notified even those who signed in with their SSO-KID appropriately. We are sorry to bother you and appreciate your understanding.

Also, you need to check the app version of Outlook only. This notification does not apply to Webmail (Outlook on the web).

Due to a misconfiguration in the authentication system for Kyushu University Microsoft 365, some email functions including IMAP, POP, and SMTP which are supposed only to allow sign-in with SSO-KID were able to be signed in with the corresponding Primary Mail Address. Since there is a security risk in allowing sign-in with email addresses, we will correct the system configuration at 10:00 on June 23.

If your email application that uses IMAP, POP, or SMTP is set to sign in with your email address, sign-in will fail and you will not be able to send or receive emails after this modification. Many email applications require you to enter your email address when setting up your account and use it for authentication as is, so please reconfirm your settings to make sure that you are using your SSO-KID to sign in.

In Outlook for Windows, select the “File” menu in the upper left to display “Account Information.” If “IMAP/SMTP” or “POP/SMTP” is displayed under your email address, select “Server settings” from “Account settings” and check the “User name.” No action is required if “Microsoft Exchange” is displayed under your email address.

In Outlook for macOS, select “Accounts…” from the “Tools” menu. If “IMAP Account” or “POP Account” is displayed under your email address, check the “User name” in “Server information.” No action is required if “Exchange/Office 365 Account” is displayed under your email address.

In Thunderbird, right-click the email address from the list on the left, select “Settings”, and check “User Name” in “Server Settings.”

For other mail apps, check the account settings to see if there are IMAP, POP, or SMTP server connection settings. Even with the above apps, the setting location may differ depending on the version.

If items such as “User name” and “User ID” are your email address, correct them to “SSO-KID@kyushu-u.ac.jp” and confirm that you can still sign in. Please also refer to the manuals of Primary Mail Service. Please make sure to reconfirm the settings of your email application before June 22.

Please use Webmail if you want to make inquiries when the mail application is not available.

We apologize for the inconvenience and thank you for your cooperation.
