How to manage mailbox storage

Why storage matters

A full mailbox may stop receiving new messages or cause email errors.

Checks

  • Log in to cPanel.
  • Open Email Accounts.
  • Check the storage used by each mailbox.
  • Delete old mail, empty trash folders or increase quota where available.

Tip

Large attachments often use the most space. Save important files elsewhere before deleting old messages.
