Understand LTSC vs. Microsoft 365 Cloud Storage Differences

Clarify the licensing limitations of Office LTSC 2021 regarding OneDrive storage capacity.

Microsoft Office LTSC (Long Term Servicing Channel) Professional Plus 2021 is a one-time purchase, standalone license. Because it is not a subscription-based model, it does not include ongoing premium cloud services.

The 1 TB OneDrive storage allowance is an exclusive benefit provided only to users with an active, eligible Microsoft 365 subscription. When using a standalone perpetual license like LTSC, your account retains the standard, free 5 GB limit.

1
Confirm your license type

Open Microsoft Word or Excel, navigate to 'File' > 'Account', and look under the 'Product Information' section to confirm you are using Office LTSC 2021 rather than Microsoft 365.

2
Check current storage capacity

Log in to OneDrive.com using your Microsoft account, click the gear icon for Settings, and select 'Options' to view your current storage breakdown.

Frequently Asked Questions

Can I buy more OneDrive storage without subscribing to Microsoft 365?

Yes, you can purchase standalone OneDrive storage plans (such as Microsoft 365 Basic, which provides 100 GB) through your Microsoft account settings without needing to buy the full premium Office application suite.

Does the standard Office 2021 release include 1 TB of OneDrive storage?

No. All one-time purchase versions of Office, including Office 2021 Home & Student, Home & Business, and LTSC Professional Plus, only come with the default 5 GB of free OneDrive storage.

How do I migrate my files if I decide to switch to Microsoft 365?

If you purchase a Microsoft 365 subscription using the same Microsoft account tied to your current 5 GB OneDrive, your storage limit will automatically increase to 1 TB, and your existing files will remain intact and accessible.
