- Device & OS
- not provided
- Scenario
- Upgrading an existing Microsoft account with free OneDrive storage to a paid Microsoft 365 Personal subscription.
- Observed behavior
- Clarifying the final total storage capacity of the OneDrive account after a Microsoft 365 Personal license is activated.
Ensure you know the exact Microsoft account credentials associated with your current OneDrive storage before activating any new Microsoft 365 subscriptions.
Check Your Upgraded OneDrive Storage Quota
Activate your Microsoft 365 subscription using your existing account and verify how Microsoft has applied the 1 TB quota to your profile.
When you upgrade to Microsoft 365 Personal, your OneDrive storage limit is increased to 1 TB (1,000 GB). In most cases, this 1 TB quota acts as an account-level cap that overrides the default free 5 GB limit, rather than simply adding to it (meaning your total available space will usually be exactly 1 TB, not 1,005 GB).
Certain legacy bonuses or promotional storage might be handled differently depending on Microsoft's current terms, so the best way to confirm your final capacity is to check your account settings after activation.
Go to the official OneDrive website and sign in with the Microsoft account used to purchase your Microsoft 365 Personal subscription.
Click on the gear icon (Settings) located in the top right corner of the page, then select 'Options' from the dropdown menu.
Navigate to the 'Manage storage' section on the left sidebar. Your new total storage limit (1 TB / 1,000 GB) and your current usage will be clearly displayed here.

Looking for a Free Alternative to Microsoft 365?
If you are hesitant about paying for a Microsoft 365 subscription just to get access to Office apps, WPS Office provides a powerful, free, and lightweight alternative. You can even connect your existing free cloud drives, including OneDrive, Google Drive, and Dropbox, directly within WPS Office to manage your files seamlessly without paying for a premium Office suite.
- 1. Download and install: Download WPS Office for free from the official website and install it on your device.
- 2. Connect your cloud storage: Open WPS Office, navigate to the 'Open' tab on the left panel, and select 'Add Cloud Storage'.
- 3. Sign in and edit: Log into your existing OneDrive or Google Drive account to directly access, edit, and save your documents in the cloud.

Frequently Asked Questions
Will I lose my files if my Microsoft 365 Personal subscription expires?
Yes, if your subscription expires, your OneDrive storage limit will revert to the free tier limit (typically 5 GB). If your saved files exceed this free limit, your account will become read-only until you free up space or renew your subscription.
Can I share my 1 TB Microsoft 365 Personal storage with others?
No, Microsoft 365 Personal provides 1 TB of storage strictly for a single user account. If you want to share storage and Office benefits with up to 6 people (where each person gets their own 1 TB), you need a Microsoft 365 Family subscription.
Does Microsoft 365 storage stack if I buy multiple years of a Personal subscription?
Buying multiple years extends the duration of your subscription but does not increase your overall storage capacity at one time. Your limit will remain at 1 TB for the entire duration of the active subscription period.
