- Device & OS
- not provided
- Scenario
- Checking cloud storage capacity limits and Microsoft 365 subscription status.
- Observed behavior
- The available OneDrive storage space is displaying as 1 TB instead of the previously available 2 TB limit.
Ensure you have your Microsoft account login credentials available to access your billing and subscription history.
Verify Your Microsoft 365 Subscription and Promotional Status
Check your Microsoft account dashboard to determine if a promotional offer or additional storage add-on has recently expired.
In most cases, a 2 TB OneDrive capacity is the result of a base 1 TB Microsoft 365 subscription combined with a 1 TB promotional offer or a separate storage add-on. When these temporary promotions or add-on plans expire or are cancelled, your account automatically reverts to the standard 1 TB limit.
Open your web browser and navigate to account.microsoft.com/services. Sign in using the Microsoft account associated with your OneDrive.
On the 'Services & subscriptions' page, look at your current Microsoft 365 plan to confirm it is active and check the baseline storage it provides.
Navigate to the 'Payment & billing' section and check your order history. Look for any expired storage add-ons or promotional deals that may have recently lapsed.
If you need the 2 TB capacity back, you can purchase an additional 1 TB of OneDrive storage directly from your account dashboard to supplement your Microsoft 365 plan.

Frequently Asked Questions
What happens to my files if my OneDrive storage decreases below my usage?
If your storage limit drops to 1 TB but you have 1.5 TB of files, your files will remain safe and accessible. However, your account will be frozen for uploads, meaning you won't be able to add new files, sync changes, or send/receive emails (if using Outlook) until you free up space or purchase more storage.
Can I upgrade my Microsoft 365 storage beyond 1 TB?
Yes. While the standard Microsoft 365 Personal and Family plans include 1 TB of storage per user, you can purchase additional OneDrive storage in increments (up to an extra 1 TB) for a maximum total of 2 TB per user.
Are there any free ways to increase my OneDrive storage?
Currently, Microsoft rarely offers free ways to permanently increase storage beyond the basic free tier (5 GB). Any significant increase, such as jumping from 1 TB to 2 TB, usually requires purchasing an add-on subscription or redeeming a temporary promotional code.
