Student email serviceAs one official form of communication between the students and university at TU, a TU official email address is distributed to all regular students. This email address can naturally be used as a communication method on campus and also for communication with students, faculty and graduate students off-campus. This page contains basic information, including information of setting necessary for using student email services (DC Mail, Digital Campus Mail).
INDEX
The student email service (DC Mail) can be used by all students at TU. User registration and other procedures are not necessary for use. Students with a TU ID are qualified to use the service.
You can log into Google Workspace to view Google Workspace Help provided by Google LLC. See here for more detailed help.
In DC Mail, you can use three types of addresses. All of these emails will arrive at the same mailbox. Note that, the storage capacity for the mailbox, including Google Drive MyDrive, is 25GB. (There is no issue with use even if the storage capacity exceeds 25GB. However, there are restrictions, such as data cannot be newly saved once the storage capacity exceeds 100GB.)
Take note of the following precautionary points regarding the student ID number email address.
In this section, we will explain the necessary initial settings and what should be done in the beginning to use DC Mail, and the login method and other settings.
Confirm the password for initial login and necessary authentication information using the TU ID confirmation page or the TU ID notification.
Access the Gmail website, click “log on” at the upper right.
Input the university-wide email address into the “email address or telephone number” field, click on “Next.”
In the “input password” field, input the initial password confirmed in section 3.1, then click “Next.” (In the event you have already created your own unique confidential password, input that password.)
The “account protection” page, as shown in the figure below, will appear. This screen is to register the communication method to receive contact from Google for account recovery, mainly in cases where the user forgets their password or is locked out of their account for security reasons. Contact addresses can be input after logging in. Click “Complete” if you do not want to input contact addresses at this time.
ID confirmation, as shown in the figure below, is required for security reasons. (This shows up primarily when an account is accessed from a device that is not regularly used.) In this case, input the Employee ID confirmed in Section 3.1.
When logging in for the first time (initial login), the software will request that you create your own unique confidential password in the screen shown in the figure below to replace the initial password. Create a password.
The password that you created here can be used as the login password when you use Google Workspace services, including DC Mail. In light of this, carefully manage this password, do not forget it and do not tell anyone else your password.
Precautions regarding the function to automatically generate a password
In the event you create a password using the function to automatically generate a password for your browser, confirm the generated password and commit to memory. In the event you create a new password and close down, without checking your password, the password you created may become unknown, therefore you will be unable to log into Google Workspace.
When logging in for the first time, the screen in the figure below will appear. Read and click on “Agree.”
Click on “Next” once the screen in the figure below appears.
When the screen in the figure below appears, select the setting of your choice, and click on “Next.”
Once the Gmail screen appears, login is complete.
For the Windows or macOS, we recommend the use of the Google Chrome browser. In the event you want to use a standard email app or some other type of email app, see Google Help.
This section explains how to use the Gmail app. In the case you want to use a standard email app that runs on iOS or iPadOS or some other type of email app, see Google Help.
Launch the Gmail app. In the event the account has not be set up, tap on “Add email address” as shown in the screen below.
Even if you have not set up an account, if you are using a DC Mail account on another Google app (Google Chrome, etc.), the screen at the bottom will appear, and your account will be displayed in the black portion. In this case, you can enable DC Mail for use by tapping on “Complete” at the upper left.
In the event you have already set up some type of account (other than DC Mail, the screen at the bottom will appear. Tap on the ‘initial’ portion at the upper right. In the screen after that, tap on “Add separate account.”
Tap on “Google”
Input university-wide email address and tap on “Next.”
Enter the Google Workspace login password, and click on “Next.”
Emails that arrive at the DC Mail address can also read after forwarding them to a separate address that you normally use. Follow the following procedures. Also refer to Google help, etc.
Log into Google Workspace. Click on the gear icon at the upper right of the screen, and then click on “Settings.”
Click on “Forward email and POP/IMAP.”
Click on “Add a new email address to which emails will be forwarded.”
Specify an email address to which you want to forward emails (email address that is regularly used, etc.), and click on “Next.”
Check to make sure the email address is correct, and click on “Continue.” Confirm the “added forwarding email address” message, and click on “OK.”
Go back to Step 3, and enable the settings for forwarding emails. Enable the radio button to “forward incoming emails to ○○…,” select options from the respective pull down menus for settings on how to handle the forwarding email address and the forward emails. Lastly, click on the “Save changes” button.
If you select “Delete email” from the pull-down menu, you will no longer be able to view the relevant email on Google Workspace. Unless there are special circumstances, we recommend you set the forwarded emails to remain in the inbox.
Note that if you click on “create a filter” in the screen in Step 3, you can set conditions for forwarded emails, and only forward those emails that match the set conditions.
There are confirmed cases where an important email was erroneously judged to be spam/junk email. In particular, there have been cases where the TU SSO authentication email was erroneously classified as spam/junk email. Even if your set your emails to be forwarded, periodically log into DC Mail and check your emails.
In DC Mail, in addition to the “university-wide email address” and “student ID email address,” an “alias university-wide email address” can also be independently acquired individually. To acquire an alias university-wide email address or to confirm your current alias university-wide email address, follow the steps below.
Access the Integrated Electronic Authentication System. See here for the access method.
Click on “update email address, etc.” from the menu on the left side of the screen.
An alias email address will be shown in the “alias university-wide email address” field (the field will be blank in the event an alias email address is not created). Input the newly set-up alias university-wide email address (portion before “@dc.tohoku.ac.jp”), and click on the “Save” button at the bottom of the screen.
Emails that are sent unilaterally, both indiscriminately and in large volume, and regardless of the intention of the recipient, to an unspecified number of recipients are known as spam or junk email. They have become a social issue. It goes without saying that you should not send junk (spam) emails yourself. Take the following precautions should you receive junk (spam) mail.
In recent years, there is an increasing trend concerning emails called targeted email attacks. This not simple spam/junk email. Normally, this is a clear intention in which the affiliated member of a specific organization or school is being targeted. This is a malicious attack. For example, an attacker impersonates a university teacher or system administrator, and makes the recipient believe that this is an “important email from the university.” It directs the recipient to a malicious website, and steals important confidential information, including account information and personal information. Even if the sender says they are a person connected to TU, and even if the address of the email’s sender (From header) looks as if it is an actual TU address, this is not always evidence enough to trust the email. Understand that the header information in the email can possibly by camouflaged by the attacker.
Consult with the Basic Technology Department, Center for Data-driven Science and Artificial Intelligence when you believe something is suspicious with an email or whenever you question your judgement.
