Your OneDrive account will be frozen if you don’t use your account for over a year, or if you exceed your OneDrive storage limit for more than three months.
To make sure your OneDrive doesn’t become frozen, use OneDrive at least once a year and stay within your storage limit. You might exceed your storage limit for any or all the following reasons:
Your account was affected by changes to the amount of free storage that comes with OneDrive.
You bought either an Office 365 subscription with 1 TB (1024 GB) of OneDrive storage, or a OneDrive storage only plan, and then you didn’t renew your subscription, or you had a billing issue. View your Microsoft Office account information.
Additional OneDrive storage that you gained through a promotion has expired.
What happens when my OneDrive is frozen?
Don’t worry, your files are still there. You just need to unfreeze your account to get access to your files again. Keep in mind, though, that you will need to unfreeze your account, or your files will eventually be deleted.
How do I unfreeze my account?
If your OneDrive is frozen because you stopped using it, sign in to the OneDrive website and follow the on-screen instructions to unfreeze it.
If you’re over your storage limit, you have two options to bring your account back into good standing:

Choose Unfreeze your account to temporarily access your files. You'll have 30 days to remove enough files to be within your storage limit.

If you don't remove enough files within 30 days, your account will be frozen once more and you won't be able to unfreeze it again. If your account is frozen again, and you have questions, sign in to the OneDrive website. At the top of the page, select ? > Email OneDrive support.
