Due to changes in Microsoft’s tenant storage capacity specifications, the storage utilization within our university has become constrained. As of November 2024 approximately 80% of the allocated storage has already been used.
Considering this situation, we will review and revise the storage limits for individual accounts and SharePoint sites in Microsoft-related services. The details decided so far are as follows:

• Implementation Period : From May 2025 (Reiwa 7)
• Target Users : Microsoft account holders under the university’s @u/@un domain
• Affected Services and New Storage Limits Post-Implementation :
  • OneDrive : Faculty/Staff: 100 GB per user, Students: 50 GB per user
  • SharePoint : 100 GB per site*

※Note: A SharePoint site is automatically created for each Teams group. Please check the storage capacity of your Teams-associated SharePoint sites.

Important Notes

• From May 2025 onwards, any OneDrive or SharePoint exceeding its storage limit will be set to “read-only”.
• We recommend taking early action during FY2024 to delete unnecessary data.
  After the limits are enforced, any OneDrive or SharePoint exceeding its prescribed limit will become “read-only,” preventing new uploads or file updates. Please back up your essential data and delete unnecessary files in advance.
  （Note: Moving files to the Recycle Bin alone does not delete them. Please ensure complete deletion from the second-stage Recycle Bin.）

Important Notes (Added May 9, 2025)

• Microsoft does not accept contracts from Individual faculty members.
• Paid additional storage costs around ¥500,000 per year for 10TB. Even though, the purchased additional storage cannot be limited to the purchaser but shared by all users.

Microsoft support for Office 2019 for Mac ended on October 10, 2023.

Therefore, we will also end the provision of the download station (software distribution management system) at our university.
Office 2019 for Mac will continue to work for a while, but please upgrade to the new version of Office from a security perspective.

For the upgrade

If you have a @u or @un email account, then using the comprehensive agreement between our university and Microsoft, you can install Microsoft 365 Office app, launch and sign in to use it.

For more details on Microsoft 365 Office (personal use of Microsoft products), please refer to Microsoft Products (for private use)/

If you use Microsoft 365 Office (which has been installed by the PC administrator user) on a PC shared by multiple users having @u or @un, please create a PC account (profile) for each user. Every user can sign in then use it after login the PC with his/her own PC account.
* Using Microsoft 365 Office from a common PC account (same ID/password) suffers from the risk that one’s OneDrive, etc., are open to access by multiple persons.

For cases such that non-member users (do not have @u or @un) to use Office on a shared PC, please contact us.
