Solution 1Recommended

Verify Your Microsoft 365 Subscription and Account Details

Check your Microsoft account online to ensure your annual subscription is active and that you are signed in with the correct email address.

Often, subscription recognition issues occur because the Office apps are logged into a different Microsoft account than the one used to purchase the subscription.

Log in to your Microsoft Account

Open a web browser and navigate to https://account.microsoft.com/services. Sign in with your primary Microsoft account credentials.

Check Services and Subscriptions

Locate the 'Services & subscriptions' section. Verify that your Microsoft 365 annual subscription is listed as 'Active' and note the expiration date.

Verify the account in the Office app

Open any Office application like Word or Excel. Go to File > Account. Check the 'User Information' section to ensure the logged-in email matches the one with the active subscription.

Sign out and sign back in

If the correct account is shown but the error persists, click 'Sign out', restart your computer, open the app again, and sign back in to force a server sync.

Verify Your Microsoft 365 Subscription and Account Details

Tip: If you have multiple email addresses (e.g., personal and work), try checking the subscription status for each one to find where the active plan is registered.

Solution 2

Resolve OneDrive Storage and Sync Issues

Check your actual cloud storage usage and troubleshoot synchronization errors to clear the 'OneDrive is full' message.

Frequently Asked Questions

Why is Microsoft 365 asking me to buy it when I already paid?

This usually happens if the desktop application is logged into a different Microsoft account than the one used to purchase the subscription. It can also occur if the payment failed to process or if the software needs to be re-synced by signing out and back in.

How do I fix the 'OneDrive is full' error when I have a 1TB subscription?

If your Microsoft 365 subscription is not being recognized by your account, OneDrive temporarily downgrades your limit to the free 5GB. Fixing the subscription recognition issue (by verifying your account under Services & subscriptions) usually restores your 1TB limit and clears the error.

Why is my Gmail not synchronizing with OneDrive?

Gmail and OneDrive do not have a native direct synchronization feature. If you were syncing attachments, you likely used a third-party automation service (like Microsoft Power Automate or Zapier). You will need to check the settings of that specific automation tool to re-authenticate your Google and Microsoft accounts.
