The stored authorization stopped working: revoked access, a password change, an admin policy.

## Payload

| Prop | Type | Default | Description |
| - | - | - | - |
| `mailbox_id` | `string` | - | mbx_… |
| `address` | `string` | - | The mailbox address. |
| `provider` | `"google" \| "microsoft"` | - | Which provider. |
| `reason` | `string \| null` | - | What the provider said, when it said anything. |

## Handling it

Prompt the customer to reconnect here. Sync has already stopped, and sends will fail with [`mailbox_inactive`](/reference/errors#mailbox_inactive) until it's fixed.

This is the one mailbox event worth paging a human about — every hour it goes unhandled is an hour of that customer's mail silently not moving.
