Whenever I email a particular iCloud email address, I get a bounce message in return.

Sending to the @iCloud.com address from Gmail:

Delivery incomplete

Mail Delivery Subsystem <mailer-daemon@googlemail.com>

There was a temporary problem delivering your message to example@icloud.com. Gmail will retry for 44 more hours. You'll be notified if the delivery fails permanently.

The response from the remote server was:
450 4.2.2 <example@icloud.com>: user is overquota

What does user is overquota mean in reference to Apple's email software?

How can this iCloud email address receive future email messages?

What does user is over quota mean in reference to Apple's email software?

The user's storage, including the mailbox, is full.

Each iCloud account is allocated a certain amount of space, much like a drive on your computer. Once that space is filled up, there's no more room to accept any more, including email.

The solution to this is for the user to "clean up" their mailbox and/or files they've stored on their account. Most of the time, this is caused by someone never deleting email. It can be remedied by deleting old obsolete mail.

Unfortunately, you as the sender can't do anything, but contact the recipient by other means (phone call, text message, etc.) and let them know of the issue.
