Microsoft 365 Reducing Storage Limits
Release Date: January 06, 2025

Microsoft is reducing the storage allocation available for Microsoft 365 (M365) services across the Colorado State University System. The change, which applies to storage used by applications and user accounts, prompted a response plan developed by a committee of professionals from across CSU to ensure uninterrupted access and support for storage needs.
Key Changes to Storage Quotas
- New Email Accounts: Starting this month, 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.
- Review C for guidance on data management.
Impact on Research and Collaborative Tools
The university acknowledges the unique storage needs of researchers and collaborative teams. Usage of Teams and SharePoint will be closely monitored to minimize potential disruptions. Departments needing additional storage can submit requests through CSU’s web tools, and researchers with high storage demands are encouraged to contact IT for tailored solutions.
No Service Interruptions
The Division of IT assures the CSU community that the transition will not result in service downtime. Over the coming months, IT will provide resources, including tips and strategies, to help users manage storage effectively.
