User Cases

Case 1: Why does my computer persistently indicate that my OneDrive is 91% full, while the storage status in OneDrive shows that I've used less than half of the available storage?

Case 2: My Office Subscription provides 1 TB of storage, and based on my assessment, I've utilized only 18 GB. However, I'm receiving a taskbar message on the desktop stating that I am exceeding my storage limit by 23 GB.

Why is Microsoft Saying My Storage is Full?

OneDrive Full Error
OneDrive Full Error

If OneDrive indicates that your storage is full, the "OneDrive full" error typically occurs when your OneDrive storage space is completely used up. OneDrive provides users with 5 GB of free storage. If you exceed this limit, you will need to either free up space or purchase additional storage.

There are 2 places that you may ignore when calculating how much storage you have used:

  • Shared Folders: If you have shared folders, be aware that OneDrive files shared with you also consume your OneDrive storage quota. If possible, ask the owner of shared folders to free up space.
  • Recycle Bin: Deleted files still occupy space in your OneDrive for 30 days until you empty the Recycle bin. Make sure to permanently delete files you no longer need.
