# Inviting External Users to Become Managed Users

export const InlineImage = ({src, alt = "", height = "1em"}) => {
  return <img noZoom src={src} alt={alt} style={{
    display: "inline-block",
    verticalAlign: "middle",
    height: height,
    width: "auto",
    margin: "0"
  }} />;
};

<div className="article_labels_list" style={{display: 'none'}} dangerouslySetInnerHTML={{__html: "Admin"}} />

You can invite a single external user to become a managed user within your organization or invite multiple external users to become managed users.

<Note>
  **Note**

  * An external user who is currently part of another Business or Enterprise account cannot be made a managed user in your organization and the option to make that user a managed user will not be available when converting a single external user. When converting unmanaged users, a message will indicate which external users cannot be converted.
  * Restrictions set by external folder owners, for example in the [domain allowlist](/en/box-admin-tools/how-to-guides-for-admins/limit-collaboration-to-allowlisted-domains), can trigger the removal of collaborations when a user is converted to a managed account.
</Note>

**To invite a single external user to become a managed user**

1. Go to **Admin Console > Users & Groups**.
2. Select the **External User** tab.
3. In the drop-down list, select **External Users**.
