If you downloaded Microsoft Office 365 for your computer from the University to use during your study, your subscription ends when your StudentMail is disabled. If you want to keep using Office 365, you will need to buy a personal copy from Microsoft.
If you are not sure whether your copy of Office is University-provided:
You can purchase your own copy of Microsoft Office 365 for personal use, home use, or business use. Office 365 provides you with online application access, as well as OneDrive storage, for a yearly subscription fee.
Alternatively you can buy the Office Suite as a one-off purchase and have the full suite of Microsoft software applications installed on your computer to use indefinitely. See the Microsoft website for more information and pricing:
You cannot transfer information directly between your student Office 365 OneDrive account and your new personal account. You will need to download, then re-upload, your files.
