To create a user mailbox in the Exchange Control Panel, follow these steps:

  1. Navigate to Manage My Organization > Users & Groups > Mailboxes > New.

  2. Enter the following information:

    • First name, Initial, Last name    These fields aren't required, but they're a good idea.

    • * Display name   This name appears in the address book, on the To and From lines in e-mail messages, and in the Mailboxes list in the Exchange Control Panel. It's required.

    • * Microsoft ID or Organization ID   This consists of the user's alias on the left side of the at sign (@), and your domain name, such as contoso.edu or fabrikam.com, on the right side. It becomes the user's sign-in ID and e-mail address. Users use their user ID to access their mailboxes. The user ID is required.

      noteNote:
      If you have accepted domains in your organization, the names of those domains appear in a drop-down list. If there's more than one domain name in this list, select one when you create a mailbox. To learn more about how to use accepted domains, see Accepted Domains.
    • * Password   It's a good idea to use strong passwords that are at least eight characters long and combine uppercase and lowercase letters, numbers, and symbols. For more information, see Password Guidelines.

    • * Confirm password   Retype the password to verify that you typed it correctly. You have to confirm the password to save the new mailbox.

    • Require password change on next logon   This option helps ensure that only the user knows the password. Make sure to encourage people to use strong passwords.

      noteNote:
      The option to require users to change their password isn't available for Microsoft Office 365 organizations.
    • Mailbox plan   A mailbox plan defines settings and permissions for the user. You can choose a mailbox plan for the user here if your organization has more than one mailbox plan. Some organizations have only one. For more information, see Mailbox Plans.

      Important   Mailbox plans correspond to Office 365 license types. When you create a new cloud-based mailbox using the Exchange Control Panel, all mailbox plans are available, even if the corresponding licenses aren't included in your organization’s subscription to Microsoft Office 365.

      Why does this matter? If you create a mailbox and assign a mailbox plan that corresponds to a license that gives users more features than you paid for, they may not be able to access their mailbox or they may lose data after you license the mailbox in the Office 365 portal. Be sure to assign a mailbox plan that supports your organization’s licenses.

  3. When you're finished, click Save.

If you have a Microsoft Office 365 e-mail organization, you must assign licenses to new mailboxes or they will be disabled when the grace period ends. For more information, see Assign a License to New Mailboxes in Office 365.

Live@edu - Import or evict existing Microsoft IDs when you create a new mailbox

In Microsoft Live@edu, when you create a new mailbox, you may receive an error message saying the Microsoft ID already exists. Why does this happen? If you used your domain name for e-mail addresses before you enrolled the domain in the cloud-based service, it's likely that many of your users created s for those e-mail addresses. This type of Microsoft ID is called an unmanaged Microsoft ID. You can't create a Microsoft ID that matches an existing unmanaged Microsoft ID. In this situation, you have to decide whether to import or evict the unmanaged Microsoft ID. For more information, see Import or Evict Existing Microsoft IDs in Live@edu.

Import the Microsoft ID

When you import the Microsoft ID, the Microsoft ID and all of its existing settings are preserved. The existing Microsoft ID is associated with the new mailbox that you create. After you import a Microsoft ID, the Microsoft ID is subject to the security and privacy policies of the organization.

When should you import an unmanaged Microsoft ID? When you're certain of the identity of the user and you want to associate that user's Microsoft ID with a new cloud-based mailbox in your organization.

Note   When you import a Microsoft ID, the properties of the existing Microsoft ID, such as first name, last name, display name, and password aren't modified by the values you specify in the New Mailbox page. But you can change these after you create the mailbox. Here's how: Change Mailbox Properties and Reset a User's Password.

Evict the Microsoft ID

When you evict the Microsoft ID, the Microsoft ID and all of its existing settings are preserved. This includes the password, Xbox Live points, and Zune points. However, the Microsoft ID is placed in a forced rename state. The user can sign in by using the Microsoft ID and its password, but then gets prompted to rename the Microsoft ID. The user must specify an e-mail address that's outside of your cloud-based domain.

When should you evict an unmanaged Microsoft ID? Whenever you don't know who owns the Microsoft ID. The owner of the evicted Microsoft ID can still sign in to the Microsoft ID, but they must rename the Microsoft ID by using an e-mail address that isn't associated with your cloud-based domain.

What happens when you evict the Microsoft ID from your domain? You can create a new Microsoft ID with the same name, but the password must be different than the password of the evicted Microsoft ID. If you encounter errors when you evict the exCoNameNoMk ID, try again by using a different password.

What's next?

After you create a mailbox, you can make changes and set additional properties. To do this, select the mailbox on the Mailbox list, and then click Details. Here's how: Change Mailbox Properties.
