License & Subscription Issues

Fix OneDrive for Mac Showing Wrong Storage Quota

Maira MehtabMaira Mehtab Sep 24, 2026 869 views

Question details

The user's OneDrive for Mac desktop client incorrectly reports that the 5 GB default storage limit is full, failing to recognize the 1 TB storage entitlement provided by their active Microsoft 365 Personal subscription.

Product
OneDrive
Device & OS
macOS
Scenario
Using the OneDrive desktop sync client on Mac after changing or upgrading a Microsoft 365 subscription plan.
Observed behavior
The Mac client displays a 5 GB storage full error and stops syncing, even though the web account correctly reflects 1 TB of available capacity. Standard fixes like unlinking, reinstalling, and restarting the app do not resolve the discrepancy.
Before you start

Log in to your Microsoft account on the web to confirm that your Microsoft 365 subscription is active and that your web dashboard reflects the correct 1 TB storage limit before proceeding.

Solution 1Recommended

Contact Microsoft Support to Refresh Your Storage Entitlement

Since local troubleshooting steps like reinstalling or unlinking the client do not work, this issue is caused by a backend synchronization failure. You must contact support to have them manually refresh your subscription status.

This error typically occurs when transitioning between Microsoft 365 subscription tiers (such as moving from Family to Personal). The local OneDrive client fails to recognize the updated entitlement from Microsoft's servers, causing it to default to the free 5 GB limit.

1
Sign in to OneDrive Web

Open your preferred web browser on your Mac and navigate to https://onedrive.live.com. Sign in with the Microsoft account linked to your active Microsoft 365 subscription.

2
Access the Direct Support Link

Once logged in, open a new tab and go directly to the OneDrive support portal using this specific link: https://go.microsoft.com/fwlink/p/?LinkId=528676.

3
Request an Entitlement Refresh

In the support request form, explain that your Mac client is stuck on a 5 GB limit despite your 1 TB subscription. Ask the support representative to 'verify and refresh your storage entitlement' on their backend.

4
Restart Your Mac Client

After support confirms they have refreshed your account, restart the OneDrive for Mac application to allow it to pull the correct storage quota.

Account Verification Required: You must be actively signed into your OneDrive web account before clicking the support link, otherwise the link may not route you to the correct internal ticketing system.

Frequently Asked Questions

Why does OneDrive on the web show the correct storage, but my Mac app shows 5 GB?

This happens when the desktop application fails to communicate properly with Microsoft's subscription servers. Even though your account has 1 TB provisioned on the web, the local client reverts to the default free tier (5 GB) until the backend entitlement is manually refreshed by support.

Will reinstalling the OneDrive for Mac app fix the incorrect storage quota?

Usually, no. If the issue is related to an account entitlement desync (especially after changing from a Family to a Personal plan), local fixes like unlinking the account, reinstalling the app, or deleting cache files will not resolve the problem. Microsoft support must refresh it on their end.

How can I verify how much cloud storage I am actually using?

You can check your true storage usage and quota by logging into onedrive.live.com. Look at the bottom left corner of the web interface, which displays your current usage against your total available limit (e.g., 52 GB used of 1 TB).
