# `disabled`: the server reported the mailbox as disabled or suspended

The detail behind a mailbox_disabled verdict: the account exists in the provider's directory but is blocked from receiving mail.

- Appears in: `smtp_reason`
- Billing: The verdict is undeliverable, so the lookup is free.

Closed accounts, suspended users and deprovisioned employees answer this way at providers that distinguish "disabled" from "unknown". Mail is rejected exactly as for a missing mailbox.

**What to do.** Remove the address; it has joined your suppression list.

```json
{
    "deliverable": "undeliverable",
    "reason": "mailbox_disabled",
    "smtp_reason": "disabled",
    "mailbox_exists": false
}
```
