Verify Subscription Status and Synchronize Accounts

This error typically occurs when Word or OneDrive is signed in with a free Microsoft account instead of the account that owns the active Microsoft 365 subscription.

Microsoft limits free accounts to 5 GB of OneDrive storage. If you purchased a 1 TB plan using one email address but are logged into Office apps with another, the system applies the lower tier limit.

To resolve this, you must confirm your subscription status online and ensure all local Office applications are signed into the correct corresponding account.

Check Active Subscriptions

Navigate to the Microsoft account website in your browser and sign in. Go to the 'Services & subscriptions' page to confirm that your Microsoft 365 Personal subscription is active and listed.

Verify Word Login Account

Open Microsoft Word, click on 'File' in the top-left corner, and select 'Account' at the bottom of the sidebar. Check the email address listed under User Information to see if it matches your subscription account.

Switch Accounts if Necessary

If the wrong email address is displayed, click 'Sign out', then click 'Sign in' and enter the credentials for the Microsoft account that has the 1 TB subscription.

Confirm OneDrive Sync Account

Right-click the OneDrive cloud icon in your computer's system tray, select 'Settings', and open the 'Account' tab. Ensure it is also signed into the correct email address to allow proper 1 TB storage utilization.

Account Processing Time: If you just renewed or purchased your subscription, it may take a few hours for the 1 TB storage quota to become fully available across all your Office applications.

Frequently Asked Questions

Why does Microsoft Word say I only have 5GB of storage when I pay for 1TB?

This happens when you are logged into Microsoft Word or OneDrive with a free, basic Microsoft account rather than the specific account used to purchase your Microsoft 365 Personal subscription.

How long does it take for 1TB storage to appear after purchasing Microsoft 365?

Generally, storage upgrades reflect immediately or within a few hours. If it takes longer, signing out and signing back into your Microsoft account across all Office applications forces a refresh.

Can I use Microsoft Word locally if my OneDrive storage is full?

Yes, you can bypass the cloud storage limit by changing your document's save location. Click 'File', select 'Save As', and choose 'This PC' to save the file locally to your computer's hard drive.

How do I check which account is signed into Microsoft Word?

Open Microsoft Word, click on the 'File' menu, and select 'Account' from the left sidebar. Your signed-in email address and subscription details will be displayed under User Information.
