# Why do I get “Mailbox does not exist” bounceback from a brand new mailbox?

Getting a 'mailbox does not exist' message can be frustrating, we know. You just need to give it half an hour.

Mailbox password changes, webmail access and sending/receiving email via a mail client are all available as soon as your mailbox has been created.

However, it can take up to **30 minutes** for our MX servers to accept new email for your new mailbox.

If you receive a “Mailbox does not exist” bounceback to a new mailbox within 30 minutes of its setup, this should be nothing to worry about. It should resolve itself as soon as our MX configuration updates.
