Cloud storage being full usually means the Microsoft cloud storage quota has been exceeded, even if a subscription is being paid for.
Key points and steps to resolve:
- Understand what is full
- Microsoft cloud storage (also called Microsoft Unified Storage) includes OneDrive files and photos, Outlook.com pictures and attachments, and other files stored with the personal Microsoft account.
- When this storage is full:
- OneDrive files become read‑only and new files cannot be uploaded, edited, or synced.
- Outlook.com cannot send or receive email, even if the mailbox itself appears under its own limit.
- Check actual storage usage and quota
- Sign in to the Microsoft account and open the storage page using the provided sign‑in entry point: Sign in.
- After signing in, select the Microsoft storage section to see:
- Total storage quota.
- How much is used.
- Breakdown across OneDrive, Outlook.com, and other services.
- Check OneDrive specifically
- If OneDrive shows as full:
- Open OneDrive on the web and select Manage your OneDrive storage.
- Empty the OneDrive Recycle Bin (items there still count against the quota).
- Use the “view largest files” option to find and delete large, unneeded files.
- If a shared folder pushed the account over quota, remove that shared folder from OneDrive.
- Check Outlook.com storage impact
- If either Outlook.com mailbox or OneDrive storage is full, email sending/receiving is blocked.
- Use the mailbox storage page (linked from the storage warning) to delete large emails, especially with attachments, and then empty Deleted Items and Junk Email.
- Verify subscriptions vs. storage
- The $1.99 charges may be for additional OneDrive storage or other subscriptions, but the effective quota is what appears on the Microsoft storage page.
- If a previous promotion or subscription expired (for example, bonus storage or a Microsoft 365 subscription), the storage quota may have been reduced, causing the account to be over quota even while another plan is being paid for.
- Check the Services & subscriptions section of the Microsoft account to confirm which active subscriptions are providing storage.
- Options to get back under quota
- Delete files/emails until total usage is below the displayed quota; or
- Buy or upgrade storage from the storage page using the built‑in Buy now or Upgrade options.
- If the account is already under quota but still shows full
- After freeing space or purchasing storage, it can take up to 24–48 hours for the status to update across services.
- If the status does not update after that time, contact Microsoft support using the Contact Support options on the storage or OneDrive help pages.
