# How to Control Mailbox Visibility

Control whether other DocStudio accounts can find your mailbox by name or alias. By default, mailboxes are hidden.

An account admin can change this setting at any time.

{% hint style="info" %}
**Corporate Account Admin** — is a user who has access to the company's account, in which a verified and active domain is registered.

* **Mailbox** — A working entity that sends, receives, stores, and processes envelopes.
* **Mailbox ID (UUID)** — A unique identifier assigned to a mailbox.

See the [Glossary](/glossary/glossary.md) for DocStudio term definitions.
{% endhint %}

1. Open **Menu** in the top-right corner.
2. Click **Admin panel**.
3. Open **Mailboxes**.
4. Find the mailbox you want to update.
5. Click **Settings**.
6. Enable or disable **Hide name/alias from other accounts**.

This setting controls whether other accounts can find the mailbox by name or alias.

### Send an envelope to a hidden mailbox

If you cannot find a mailbox by name, use one of these options:

* recipient email
* mailbox UUID
* saved contact

### Send by email

1. Start creating an envelope.
2. Enter the recipient email address.

If the recipient has a default mailbox, routing is automatic. If not, the recipient must accept the envelope.

### Send by mailbox UUID

{% hint style="info" %}
The **mailbox UUID** is a unique identifier for a mailbox in DocStudio. If you need to find a mailbox UUID, see [How to Find a Mailbox ID (UUID)](/user/mailbox/mailbox-user/how-to-find-a-mailbox-id-uuid.md).
{% endhint %}

Enter the recipient mailbox UUID in the recipient field. You can copy it from previous envelopes. This works even if the mailbox is hidden.

### Add a hidden mailbox to your contacts

Add the mailbox to **Contacts** first. Then reuse it when you create an envelope.

For the full step-by-step flow, see [How to Add a Contact to a Mailbox](/user/mailbox/mailbox-user/how-to-add-a-contact-to-a-mailbox.md).
