Every mailbox includes a basic amount of storage. When a mailbox needs more, you give that one mailbox a bigger size; the others stay as they are. This article also covers the **allowance**: how many mailboxes an email-only domain may have.

## The sizes

The smallest size in the menu is included with every mailbox and marked **included**. The larger sizes are priced per mailbox:

- Mailbox storage — 10 GB: €1 per mailbox / month
- Mailbox storage — 25 GB: €2 per mailbox / month
- Mailbox storage — 50 GB: €4 per mailbox / month

When a mailbox is full, new mail for it is refused until there is room again.

## See how full a mailbox is

Open [Email](https://manage.veldhost.eu/portal/mail) and choose the domain. The **Storage** column shows each mailbox as *used / size*, as the mail server last reported it. A dash means the mail server has no figure yet (for example, before the first mail arrives) or could not be asked just now.

## Change a mailbox's size

1. Open [Email](https://manage.veldhost.eu/portal/mail) and choose the domain.
2. Open the mailbox's **⋯** menu and choose **Change storage**. It shows the current size and, beside each other size, its price.
3. Choose a size. The **Change storage** confirmation says what the mailbox will cost and what your account's bill becomes.
4. Choose **Make it SIZE** to confirm.

The page then says how much mail the mailbox can now hold. A bigger size is billed from today, prorated: you pay only for the rest of the current billing period.

The same **Change storage** menu is on a site's mailboxes, under [Email](https://manage.veldhost.eu/portal/mail) → your site's domain.

Things to know:

- **Making a mailbox bigger changes the bill**, so it needs a role that can both manage domains and handle billing; in practice, the account owner (see [roles and permissions](https://veldhost.eu/docs/roles-and-permissions)). Anyone else who can manage domains sees "More space changes the bill: ask whoever handles billing."
- **Making a mailbox smaller** only works if its mail fits. If it holds more than the new size, nothing changes and the page asks you to delete or move some mail first.
- A mailbox marked **separate contract** keeps the size of that contract and has no **Change storage** option.
- If our payment provider cannot be reached, nothing changes and the page says so. Try again in a few minutes.

## Change how many mailboxes a domain may have

On an email-only domain, the **Mailboxes** heading shows how many are in use out of your allowance (for example, *3 of 5*). To change it:

1. Open [Email](https://manage.veldhost.eu/portal/mail) and choose the domain.
2. Beside **Mailboxes**, choose **Change allowance** (or **Raise the allowance** when every mailbox is in use).
3. Enter the new number under **Allowance** and choose **Change**.
4. The **Change the allowance** confirmation shows the price per mailbox and your account's new total. Choose **Change allowance**.

You cannot go below the number of mailboxes you already have: remove one first. Only someone who handles billing sees this option.

For a site with email, raise the number with **Add a mailbox** on the site's email page instead; see [create an email address on your domain](https://veldhost.eu/docs/create-a-mailbox).
