STORAGE_LIMIT_EXCEEDED

The org has run out of data or file storage, so new records cannot be created.

Common causes

• Accumulated tasks, email messages, logs or history records.
• A large data load.
• Small sandboxes filling up quickly.
• Many file versions stored as ContentVersion records.

How to fix

• Open Setup → Storage Usage to see which objects use the most space.
• Delete or archive old records, starting with the largest objects.
• Remove old file versions and unused attachments.
• Move historical data to Big Objects or an external store.
• Purchase additional storage if the growth is legitimate.
