not provided
Scenario
Checking cloud storage quotas and attempting to access or add files to the OneDrive Personal Vault on a mobile device.
Observed behavior
The extra storage from a Microsoft 365 subscription is missing, and the Personal Vault incorrectly blocks new files by claiming the maximum file limit is reached.
Before you start

Ensure you are logged into the correct Microsoft account and have a stable internet connection before checking your subscription details and syncing status.

Solution 1Recommended

Verify Your Microsoft 365 Subscription and Storage Settings

Confirm that your account has an active Microsoft 365 subscription to unlock the 1 TB storage and remove the Personal Vault file limit.

1
Access Microsoft Account Settings

Navigate to the Microsoft Account website on your browser and click on the 'Services & subscriptions' tab.

2
Check Subscription Status

Verify if your Microsoft 365 subscription is active and ensure you are logged in with the correct account (personal vs. work/school).

3
Review OneDrive Storage

Check your OneDrive storage settings to confirm it reflects the 1 TB allocation from your subscription instead of the standard 5 GB free limit.

Frequently Asked Questions

Why does my OneDrive Personal Vault say it is full with only two files?

Free OneDrive accounts limit the Personal Vault to a maximum of three files. Syncing errors, hidden files, or unverified documents can invisibly take up the third slot. Checking via the OneDrive web version often reveals the hidden file.

How much storage comes with a standard OneDrive account?

A free OneDrive account includes 5 GB of storage. To expand this to 1 TB and remove the Personal Vault file limit, you must subscribe to an eligible Microsoft 365 plan.

Why isn't my Microsoft 365 extra storage showing up on my phone?

This usually happens if your phone is logged into a different account (such as a free personal account instead of a work or school account), or if the app has not synced properly. Verify your active account under Microsoft's Services & subscriptions page.
