Microsoft has announced that it will change its charging policy for M365 services for higher education institutions worldwide, and will charge based on our data storage capacity of M365 online service.

ICTO has reassessed the usage of these services and has decided to change the personal storage quota for UM@Connect and OneDrive. We will maintain continuous oversight of any adjustments made by the service provider to its billing methods, and will make suitable changes to the University’s usage of M365-related services, to ensure that the university can continue to provide cloud information services with reasonable resources.


Starting from December 1, 2023, the storage space for Microsoft Office 365 users at the University of Macau will be adjusted as follows:

M365 ServiceTarget UserNew Personal Quota
UM@Connect Lifelong Email ServiceStudent, Alumni10 GB
OneDrive Cloud StorageStaff, Student10 GB


As mentioned above, if your storage for Microsoft Office 365 services exceeds or is close to the new storage space limit, you will receive an email notification from Microsoft.

If your storage exceeds the storage space limit:

  • You will still be able to log into your Microsoft Office 365 account.
  • You will not be able to upload, edit, or sync new files. Your existing files will remain unchanged but will become read-only.
  • You can delete files to free up storage space.

If you need to take steps to reduce your storage space usage, here are some suggestions:

  • Find and delete large files, ZIP files, or other compressed files that are no longer needed.
  • Compressing large files can reduce the size of the files, thereby saving storage space.
  • Your recycle bin also takes up your storage space. Go to the recycle bin and choose to empty it.
  • Move unnecessary files out of OneDrive and store infrequently used files and data on external hard drives or cloud storage to free up storage space.
  • UM Staff can consider moving departmental or work-related files to the UMDrive platform.
