What Happens if My cPanel Mailbox Is Full?

A mailbox has a set storage limit that determines how many emails and attachments it can hold. When this limit is reached, new messages may not be delivered until space is made available.

This article explains what happens when a mailbox is full and outlines its impact on sending and receiving emails.

What Happens If Mailbox Is Full?

If your cPanel mailbox is full, new emails won’t be delivered. Instead, they’ll be returned to the sender with a message that your mailbox has reached its limit.

To start receiving emails again, you’ll need to either delete old messages or increase your mailbox storage limit.
