The “cloud data salvage” described on this page (a special measure to temporarily provide access to your data or account from your period of enrollment after your UTokyo Account has been revoked) will be available for application from October 1, 2025. Pre-linking in the “UTokyo Account Identity Verification Service” will be available from the evening of September 10. Please ensure you complete the pre-linking process before you leave the university.
When you leave the University of Tokyo upon graduation, resignation, etc., your UTokyo Account will be revoked at the end of your period of enrollment, and you will no longer be able to sign in. Therefore, if you wish to continue using data stored in various information systems such as Zoom, ECCS Cloud Email, and Microsoft 365, you must back up your data by following the procedures on the “Backing Up Your Data When Leaving the University” page.
However, if for some reason you are unable to create a backup before leaving and you have a justifiable reason to access your data or account after you have left, we may be able to provide exceptional access to some of your data or account under certain conditions. This is a special measure called “cloud data salvage”. By using cloud data salvage, you can temporarily back up your ECCS Cloud Email history and data on Google Drive/OneDrive, or add email forwarding settings to your ECCS Cloud Email.
This page explains the conditions and application procedures for requesting the cloud data salvage measure.
Please note that this service will commence on October 1, 2025, and will be operated on a trial basis for the time being.
Conditions for Using Cloud Data Salvage
There are several conditions for using cloud data salvage. Please understand the following conditions before applying.
- Who can apply: Former members of the University of Tokyo who have left due to graduation, resignation, etc., and are within 180 days of their UTokyo Account being revoked.
- Please note that even within 180 days of account revocation, some or all of your data may be permanently deleted and become unavailable due to circumstances such as overall university storage capacity. Please be aware that the fundamental principle is to back up your data before you leave.
- Eligible Services: Among the cloud services available with a UTokyo Account, the following are eligible.
- ECCS Cloud Email account
- We will enable you to log in to your ECCS Cloud Email account with a special password, without going through your UTokyo Account.
- This will give you access to all data within the Google system, such as Gmail and Google Drive.
- You will also be able to perform various operations within your Google account, such as adding a forwarding setting in Gmail.
- However, for email addresses from the Mail Hosting Service (only in Japanese) (email addresses with domains other than
g.ecc.u-tokyo.ac.jpthat can be used with ECCS Cloud Email), please consult the respective domain administrator separately.
- Files stored on OneDrive
- Access is not provided to the Microsoft account itself under the UTokyo Microsoft License; rather, we only provide a means to salvage files stored in your personal OneDrive.
- Therefore, data from the Email System for Staff, Teams, and Teams team drives are not eligible.
- Additionally, data from services like Microsoft Forms and Power Platform (Power Automate, Power Apps, etc.) are not eligible as they do not exist in a format that can be downloaded as files from OneDrive.
- ECCS Cloud Email account
- Identity Verification: To confirm that the applicant is the owner of the UTokyo Account, you must have pre-linked with the UTokyo Account Identity Verification Service during your enrollment and still possess a My Number Card at the time of application.
- Other Conditions:
- You can use the cloud data salvage service only once for each service (ECCS Cloud Email and OneDrive). If you apply for both services at the same time, you can use the service only once.
- The access period is limited to one week. Please complete the necessary backups and forwarding settings during this period.
- Please note that applications for cloud data salvage are not always approved. We may decline your application depending on the reason provided.
Application Procedure
If you wish to apply for cloud data salvage, please do so through the “UTokyo Account Identity Verification Service”. If you are unable to use the UTokyo Account Identity Verification Service, please see “Procedure for When the UTokyo Account Identity Verification Service is Unavailable”.
// Instructions on the procedure will be added here.
You will be notified of the approval or rejection of your cloud data salvage application by email. If your application is approved, please back up your data, set up forwarding, etc., within one week, following the instructions on the “Backing Up Your Data When Leaving the University” page.
Procedure for When the UTokyo Account Identity Verification Service is Unavailable
As a general rule, the “UTokyo Account Identity Verification Service” is used for identity verification for cloud data salvage. However, if you are unable to use this service, we will accept your application on an exceptional basis provided that you meet both of the following conditions:
- You were enrolled at the University of Tokyo as a student immediately before leaving.
- You have consulted with the academic affairs office of your former college/faculty/graduate school and have obtained their cooperation for identity verification.
If you wish to use the cloud data salvage service, please contact the academic affairs office of the college/faculty/graduate school you belonged to immediately before leaving. Inform them that you would like to retrieve data from your UTokyo Account and request identity verification and forwarding of your request to the utelecon support desk, and provide them with the following required information.
- UTokyo Account (10-digit Common ID + @utac.u-tokyo.ac.jp)
- Student ID number immediately before leaving
- Full name
- College/faculty/graduate school immediately before leaving
- Reason why this measure is necessary (Please provide a specific reason why this measure is absolutely necessary. For example, “I failed to back up a portion of my research data from my time as a student, and it is essential evidence for a paper I am submitting.” Simply stating the reason for not having been able to back up, such as “I forgot to back up,” may not be sufficient for approval.)
- Target services for access provision (ECCS Cloud Email, OneDrive, or both)
- Applicant’s contact information (email address)
Please note that subsequent communication will be conducted through the utelecon support desk’s email form, so please read the notes on the “Email Form page” in advance.
Note for staff in departmental offices: Please conduct identity verification using an appropriate method as determined by your department, such as checking official photo identification documents. While we assume this will be done in person, if unavoidable, it can be conducted via a web conference (e.g., Zoom) that allows for video exchange. Once the applicant’s identity has been verified, please contact the utelecon support desk via the email form with the required information. Further details will be provided through internal communication.
