Your OneDrive will be frozen if you haven't signed in during the last 12 months. To prevent OneDrive from freezing, you must either:
Sign in to the OneDrive website at least once a year.
Use OneDrive on your computer, Xbox or mobile device at least once a year.
What happens when my OneDrive is frozen?
Don’t worry, your files are still there. You just need to unfreeze your OneDrive to get access to your files again.
Important: You will need to unfreeze your OneDrive within 12 months, or your files will eventually be deleted.
How do I unfreeze my OneDrive?
If your OneDrive is frozen because you stopped using it, choose one of these options:
Sign in to the OneDrive website and follow the instructions to unfreeze it.
Sign in to the OneDrive mobile app and follow instructions to unfreeze it.
Note: It can take up to 48 hours to unfreeze your OneDrive.
What happens if I do nothing after my OneDrive is frozen?
Your OneDrive and all files within it (including OneNote notebooks stored in OneDrive) will be deleted on or after the date indicated on OneDrive.com when you sign in. This will not affect content you may have in other Microsoft services such as Outlook.com or Xbox.
