# Bounce address warning

If an email sent to an address you enter in To, Cc or Bcc has bounced in the last 90 days, a yellow warning appears in the compose window 1: how many times, when it last happened and the reason, if any. It does not block sending.

- Every user who writes emails (only the history of mailboxes they can see)

## What is a bounce address warning?

If mail sent to an address you enter in the To, Cc or Bcc field in the last 90 days has bounced, a yellow warning appears on the compose screen 1: how many times, most recently when, and the reason if any. Who can do this: Every user who writes mail (history of only the mailboxes they can see).

## How it works

- The source is undeliverable mail notifications and outgoing mails that could not be delivered.

- Only the history of mailboxes you can see is searched; correspondence from another mailbox is not visible this way.

- The warning appears shortly after you enter the recipients.

**Tip**Is it an address typo, or has the person left? The reason in the warning usually gives the answer. If the address has been corrected, you can still send.
