Reduction of the storage capacity available on OneDrive for Business

Thank you for your continued understanding and cooperation in the operations of the Information Infrastructure Initiative.

Due to changes in the specifications of Microsoft 365 for educational institutions by Microsoft, the storage capacity available to the entire University will be limited to approximately 610 TB from the 2025 academic year. Once the capacity limit is exceeded, all OneDrive and SharePoint data for all users will become read-only and it will no longer be possible to save new files or write to existing files.
As announced in a simultaneous notification email dated 20 December 2023, the maximum storage capacity of each user’s OneDrive will be reduced. We apologize for the inconvenience and hope you understand.

The new limits, what we would like you to work on, and the schedule for the future are as follows

◆ Limits

• Student: 100 GB
• Faculty: 400 GB
• Staff: 100 GB (including emeritus professors)

◆What we would like you to work on

• Users will organize, back up and delete unnecessary data on their own.
• Users are requested to move large data to other storage facilities as necessary.
• Faculty will also consider the use of a storage system for research data management (QRDM).

◆Future schedule

• June 2024: Notification of new capacity limit values and timing of application (this notification)
• From July 2024: Users exceeding the new capacity limit will be notified.
• Dec 2024-: Start of paid service to relax capacity limits (limited to faculty members).
• End-December 2024: deadline for users to voluntarily delete their own data
• Jan 2025-: compulsory deletion of excess data
• April 2025: new capacity limits start.
  (All files on OneDrive will become read-only for users who have exceeded the limit)

We apologize for the inconvenience, but we kindly ask you to delete unnecessary data and migrate to other storage by the end of December 2024.
