Microsoft 365 reducing storage limits for the CSU System
Microsoft is reducing the storage allocation available for Microsoft 365 services across the California State University System.
The change, which applies to storage used by applications and user accounts, prompted a response plan developed by ITS to ensure uninterrupted access and support for storage needs.
Key changes to storage quotas:
- New email accounts: Starting January 19th 2026, new Exchange mailboxes will have a quota of 5 GB. Currently, 94% of existing mailboxes use less than this.
- Existing mailboxes: All existing mailboxes will receive a new quota that is 5 GB above their current usage, ensuring no accounts will be cut.
- OneDrive quotas: New instances will have a 5 GB quota, and existing OneDrive accounts will have a new quota that is 5 GB above their current usage.
Actions for faculty, staff and students:
- Take this opportunity to clean up digital files and reduce clutter.
- Migrate their files to the approved cloud storage solution .
The university acknowledges the unique storage needs of researchers and collaborative teams. Departments needing additional storage can submit requests through the Service Center, and researchers with high storage demands are encouraged to contact the ITS for tailored solutions.
No service interruptions:
ITS is assuring the campus community that the transition will not result in service downtime. Over the coming months, ITS will provide resources, including tips and strategies, to help users manage storage effectively.
