Give a mailbox more space if it's filling up.

1. Log in to cPanel and go to Email > Email Accounts.
2. Find the account and click Manage.
3. Under Storage Space, raise the quota or set it to Unlimited (if your plan allows).
4. Click Update Email Settings.

Note: Total email storage still counts toward your hosting disk space (article 56). If you're short on space overall, clear large folders and Trash, or upgrade your plan.
