Notes (Students who are enrolled in or after FY 2017)
- If you are a Credited Auditors, etc. and the YY of sYYnnnnn is 16 or less, please refer to “How to use E-mails (Students who were enrolled in or before FY 2016)“.
- Your email address is the @s address (s + the last seven digits of the student ID number @s.tsukuba.ac.jp).
- Emails sent to your @u address (s + the last seven digits of the student ID number @u.tsukuba.ac.jp) are automatically transferred to your @s address. Make sure to establish an environment where you can receive the emails sent to your @s address without fail.
- @s address is used through Microsoft Office 365 cloud mail service.
- Separately from the @s address, students enrolled in our university can install Microsoft Office on personal devices at no additional cost and use Office 365 cloud services excluding email service, thanks to the Microsoft Office EES privilege. To registrate with Microsoft to take these benefits, sign up by using the @u address.
On the other hand, regardless of whether you registrate or not, you can use @s address. - If you have registrated as above, please note that the services available by signing in to Office 365 with the @s address and with the @u address are different. In particular, in order to do @s address setting in Office 365 from the state signed in with the @u address, it is necessary to sign out once and sign in again with the @s address.

Forwarding to another email address
To forward emails which will be sent to @s address to another email address automatically, refer to the following page:
- Mail Forwarding Setup (Office 365) (@s address → another email address)
Please make sure to carefully read the notes mentioned at the beginning of the page above, especially not to create a loop on the forwarding route.
Before replying to the forwarded email, pay attention to the sender address of your reply mail (it will normally be the address of the forwarding destination you are reading the email, but it depends on your setting). If you want to send mail with @s address as the sender, use the following Web mail or something.
Web mail
To use Web mailer, please follow the link below:
- Office 365 (@s address)
Username and password:
- Username: “s” + last 7 digits of your Student ID Number
- Password: Password for the Unified Authentication System
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.):
Confirming mailbox usage
The upper limit of mailbox usage is as follows. Please occasionally check the usage, delete unnecessary emails, backup the necessary emails before deleting, etc. Please be careful to fit within the capacity limit. In addition, if you keep track of your usage, the possibility of being cheated by a fraudulent email will also decrease.
| Email address | Uppper Limit | How to confirm |
| @s address (...@s.tsukuba.ac.jp) | 100 GB | After signing in to Office 365, click on the gear icon at the upper right corner, select “Mail (メール)” in “My app settings (アプリの設定)” section, and click on [General (全般)]-[My account (マイ アカウント)] in the appeared menu. Then your mailbox usage will be displayed at the lower right. |
How to move your email data to another location
There are several ways to move your necessary emails to another location. Here is an example, so please do it in a way that suits you.
* If you are going to back up emails using email software which you do not normally use, please check the settings carefully, such as, whether it is set to delete old mail automatically.
Moving to a local folder of an email client
There is a method of retrieving emails by IMAP or POP with email software such as Outlook or Thunderbird, and moving the emails to a local folder (or a folder of another email account) of the email software. Here we will show how to do with Thunderbird (IMAP access) as an example.
- First, you need to create a new folder under “Local Folders”. Right-click “Local Folders” and select “New Folder” from the pulldown menu.

- Enter an arbitrary name, and a new folder will be created.
Drag and drop the desired message in the Inbox to the new folder.
Make sure that the message is moved to the new folder. (In the same way, you can also put it back.)
When the message is deleted from the Inbox, the amount of your mailbox usage will decrease as much. - If you created a folder under the Inbox, you can also copy (drop) the whole folder under the “Local Folders”. After making sure that the original messages are copied in the new folder, if you delete the original folder, the amount of your mailbox usage will decrease as much.
Mail Filtering by the Mail Server
All e-mails sent and received in Office 365 Mail (@s mail addresses) are scanned by the mail server of Office 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
