Have 1TB available but OneDrive wont upload and says "Not enough cloud storage"

It sounds like your OneDrive storage is not syncing correctly with your subscription, and your PC still thinks you have only 5GB instead of 1TB. Since you've already tried resetting OneDrive (is that correct?), let's focus on other possible issues:

1. Check If Your OneDrive Plan Is Correctly Applied

Even though you just subscribed, sometimes Microsoft takes time to update storage limits.

• Go to OneDrive Storage and confirm it shows 1TB (not 5GB).
• If it still says 5GB, your Office 365 subscription may not be activated correctly. Try signing out and back in.

  2. Force OneDrive to Recognize the New Storage

Since your PC still thinks you have only 5GB, try forcing an update:

• Sign out of OneDrive completely from your PC.
• Unlink your OneDrive account from Settings > Account > Unlink this PC.
• Restart your computer and then sign back into OneDrive.
• Check if OneDrive now recognizes 1TB.

  3. Check for Multiple Accounts

Are you sure you’re using the same Microsoft account on both your PC and OneDrive website?

• Go to OneDrive settings on your PC and check the email address.
• Compare it with the email on OneDrive Web (https://onedrive.live.com/login).

Sometimes, users mistakenly log into a free OneDrive account (5GB limit) instead of their Office 365 account (1TB limit).

4. Try the OneDrive Troubleshooter

Microsoft has a built-in tool to detect and fix OneDrive issues.

• Download the OneDrive Troubleshooter from Microsoft.
• Run it and check if it detects incorrect storage limits.
