EES - Account and Authentication
I signed in with an email address ending with @ u.tsukuba.ac.jp, but I can not use Office. What should I do?
Information signed in with other previous accounts such as @s.tsukuba.ac.jp account may be saved in the browser cache and cookies. Because of this, even if you intended to be signed in at @u.tsukuba.ac.jp, you may be signed in at @s.tsukuba.ac.jp.
Please delete your browser cache and cookies, or check if it’s available in other browsers such as “Microsoft Edge”, “Google Chrome”, “Firefox”, or use different device.
I forgot my password.
Go to https://login.microsoftonline.com/, select “Select Account” > “Forgot Password” on the “Enter Password” screen, and follow the instructions to reset your password.
I entered the Unified Authentication System password but cannot log in.
Logging into the Office 365 Portal requires a new password, which is defined by the user upon signing up for EES advantages instead of the unified verification password.
How is this service related to my personally registered Microsoft ID?
Apparently, you can receive some charge-free services from Microsoft by creating a Microsoft ID using your personal email address. That is not related to this service of ours. We do not recommend using your @s, @u or @un email address to create your Microsoft ID. That could cause a problem when you receive services from the University of Tsukuba.
