OneDrive storage mismatch between web (2TB) and PC (5GB) – Microsoft 365 Family

Question

Hello everyone,

I’m currently using a Microsoft 365 Family subscription (MCS265 Family plan), but I’m experiencing an issue with OneDrive storage not displaying correctly across platforms.

• On the OneDrive web version, my storage shows 100GB used out of 2TB, which seems correct for the Family plan.
• However, on my PC (OneDrive desktop app), it shows 100GB used out of 5GB, and I receive a “storage full” notification.

Because of this mismatch, I cannot sync files from my computer to OneDrive.

What I have checked so far:

• I am logged into the same Microsoft account on both web and PC.
• My Microsoft 365 Family subscription is active.
• I have already accepted the Family sharing invitation.
• Unlink and relink my account with onedrive

Please help me fix this. Thank you!

Go to the OneDrive icon on the taskbar, then click "View online". That will take you to your linked account. Are you linked to the Family plan account?

Answer 2

Hi!Welcome to Microsoft Q&A forum.

This is a very common Microsoft 365 Family issue. Most likely the PC is being connected to the wrong OneDrive quota/account state, even if they appear to be the same. Let's check few steps and see what's happening.

Step 1: Open: https://account.microsoft.com/services

Check:

• Your Microsoft 365 Family is active
• Under sharing → your account shows as a member

Next, open: https://onedrive.live.com then go to Settings → Storage

Make sure it says 2TB (not 5GB)

Once done checking and still the same go ahead and proceed with theses steps.

Step 2: Fully reset OneDrive

• Press Windows + R
• Paste this:
  • %localappdata%\Microsoft\OneDrive\onedrive.exe /reset
  • Press enter and wait for it to complete 1-2mins
• If OneDrive doesn’t reopen:
  • Press Windows + R again
  • Run:
    • %localappdata%\Microsoft\OneDrive\onedrive.exe

Let me know once done so you can check again that status on your PC.

On the web, the correct 2 TB quota is already visible, so the issue is with how the OneDrive desktop app is seeing the quota.

Follow these steps in order:

1. Confirm the updated quota is visible
   • Go to the OneDrive Manage storage page: https://onedrive.live.com/?v=managestorage
   • Refresh the page and verify it shows the full 2 TB and the same usage as the web view.
   • If the new quota was only recently applied, wait up to 24 hours for it to fully propagate.
2. Force the desktop client to pick up the new quota Since unlinking/relinking was already tried, repeat it after confirming the quota on the web:
   • Right‑click the OneDrive icon in the taskbar/notification area.
   • Select Settings > Account > Unlink this PC.
   • Sign in again with the same Microsoft account that shows 2 TB on the web.
   • Complete setup and let it resync.
3. Check for local disk space issues The “storage full” message on the PC can also be caused by local disk space, not just cloud quota.
   • Run the Disk Clean‑up utility (Start > Disk Clean‑up in Windows) to free local space.
   • Move or delete unneeded local files.
   • Try syncing again. For details, see the guidance in I'm getting a "Disk full" message in OneDrive.
4. Reduce what is synced locally (if the PC disk is small)
   • Right‑click the OneDrive icon > Settings > Account > Choose folders.
   • Deselect large folders that do not need to be stored on the PC.
   • After sync completes, right‑click large files/folders in the OneDrive folder and choose Clear space to make them “online‑only” and free local disk.
5. Verify the correct account type and sharing
   • Ensure the signed‑in account on the PC is the Family subscription member account (not a different personal account with only 5 GB).
   • In a Family subscription, each person gets their own 1 TB; storage is not pooled. The desktop app must be signed into the specific member account that owns the 1 TB.

If, after 24 hours from purchase/upgrade and after unlinking/relinking, the desktop app still shows 5 GB while the web shows 2 TB/1 TB for that same account, contact Microsoft support with screenshots of the Manage storage page and the OneDrive desktop account page so they can correct the quota mapping on the service side.
