Method of responding when "It is necessary to update your account" is displayed

Outline

In relation to new Keio Mail that began service on November 11 (Tuesday), people who are using a Keio ID (for example, “keio-taro@a2.keio.jp”) as a Google Account will, after logging in to publicly available Google services, be sent information displayed as “It is necessary to update your account.” This means that information that trouble has occurred in a publicly available Google Group or Google Calendar use is sent.

Causes

This occurs when, during processing of the migration to the new Keio Mail system, a Keio ID (for example, keio-taro@a2.keio.jp) was also set to permit use on G Suite (formerly Google Apps), it is recognized that both the email addresses (login user names) of an individual and as Keio University have been registered as Keio ID (for example, keio-taro@a2.keio.jp) for Google services and it is impossible to distinguish them (conflict between accounts) has occurred.
