How to use e-mails (Students who were enrolled in or before FY 2022)

Notes (Students who were enrolled in or before FY 2022)


This page is being updated and may be revised
The following information will be reflected after 18:00 on March 5, 2023.
Please use Webmail if you experience any trouble after the mail system migration.

  • You can use your @s.sukuba.ac.jp (abbreviated @s ) and @u.sukuba.ac.jp (abbreviated @u ) separately. Make sure to establish an environment where you can receive all the emails sent to either the @u or @s address according to your convenience.
  • @u and @s address is used through Microsoft 365 cloud mail service.
  • Students enrolled in our university can install Microsoft Office on personal devices at no additional cost and use Microsoft 365 cloud services, thanks to the Microsoft Products (for private use). Students do not need to sign up for Microsoft 365 on their own.
    On the other hand, regardless of whether you registrate or not, you can use @s address.
  • Please note that the services available are different when signing in to Microsoft 365 with an @s address versus signing in to Microsoft 365 with an @u address. In particular, you will need to sign out and then sign back in with your @u address in order to set up your @u address in Microsoft 365 when you are signed in with your @s address. If you find this inconvenient, use the private mode of your browser, or use the client software only for @s addresses, and use the browser for @u addresses (e.g., for the cloud service of M365).

Web mail

To use Web mailer, please follow the link below:

Username (User ID) and password:

[@s addresses are allowed only to send/receive e-mail on Microsoft 365]
Though after signing in the Microsoft 365, some functions may be open unexpectedly, you are not supposed to use functions other than sending/receiving e-mail.
Any so created contents will be deleted by the system without warning.

Web mailer can be used from any device if the browser works, which is very useful. However, depending on each person, the user interface and operation (keyboard shortcut etc.) may not fit. If you want to use from other familiar email software or other web mailer (Gmail etc.), please refer to “Other email clients” below.

Other email clients

Please refer to the following when reading / writing email from email software such as Outlook or Thunderbird or other web mailer (Gmail etc.):

Mail Filtering by the Mail Server

  • All e-mails sent and received in Microsoft 365 Mail (@u and @s mail addresses) are scanned by the mail server of Microsoft 365 for phishing and malware e-mails.
  • E-mails that are determined to be those e-mails will be filtered and will not reach the recipients.
  • Neither the sender nor the destination user is notified that it has been filtered.
  • The filtered e-mail is discarded and cannot be resent unless the sender user has saved it separately.
    Even the site administrator cannot change the filtering status and settings.
