How to Fix Missing OneDrive Storage and Personal Vault File Limit Errors
Question details
The user is not receiving their expected additional OneDrive storage on a mobile device and is encountering a Personal Vault limit error stating there are three documents when only two are visible.
- Product
- Microsoft OneDrive
- Device & OS
- 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.
Ensure you are logged into the correct Microsoft account and have a stable internet connection before checking your subscription details and syncing status.
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.
Navigate to the Microsoft Account website on your browser and click on the 'Services & subscriptions' tab.
Verify if your Microsoft 365 subscription is active and ensure you are logged in with the correct account (personal vs. work/school).
Check your OneDrive storage settings to confirm it reflects the 1 TB allocation from your subscription instead of the standard 5 GB free limit.
Check Personal Vault Files via OneDrive Web
Use the web version of OneDrive to identify hidden files or sync issues causing the incorrect file count in your Personal Vault.
Reset the OneDrive Mobile App
Resetting the app can resolve syncing glitches that cause storage quotas and Personal Vault limits to display incorrectly on your phone.

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.
