Usage on staff's office PC environment is a separate tenant, so it is not subject to this change.

Until the end of March 2025: 1TB

After April 2025: 50 GB (*)

(*) Capacity will be increased or decreased based on future usage.

Since October 2025, the limit has been set at 100 GB.

The used capacity will be displayed in the lower left corner of the screen.

Reason for change in usage capacity

Microsoft had offered academic institutions unlimited storage service capacity for tenants, with a storage capacity limit of 1TB for each user, but due to changes in Microsoft specifications, the total storage capacity for the entire tenant will now be limited.
