1. In the EAC, navigate to Recipients  > Mailboxes.
   
   
2. Click New > User mailbox.
   
   
3. On the New user mailbox page, in the Alias box, type the user’s alias, which specifies the email alias for the user. The user’s alias is the portion of the email address on the left side of the at (@) symbol. It must be unique in the forest.
   
   

   Note:
   If you leave this box blank, the value from the user name portion of the User logon name is used for the email alias.

4. Select one of the following options:
   
   
   • Existing user   Select to mail-enable and create a mailbox for an existing user.
     
     Click Browse to open the Select User – Entire Forest dialog box. This dialog box displays a list of Active Directory user accounts in the forest that aren't mail-enabled or don't have Exchange mailboxes. Select the user account you want to mail-enable, and then click OK. If you select this option, you don’t have to provide user account information because this information already exists in Active Directory.
     
     
   • New user   Select to create a new user account in Active Directory and create a mailbox for this user. If you select this option, you'll have to provide the required user account information.
     
     

   Note:
   The Active Directory account that is associated with user mailboxes must reside in the same forest as the Exchange server. To create a mailbox for a user account that resides in a trusted forest, you have to create a linked mailbox. See Manage Linked Mailboxes.

5. If you selected New user in Step 4, complete the following boxes on the New user mailbox page. Otherwise skip to Step 7.
   
   
   • First name   Use this box to type the first name of the user.
     
     
   • Initials   Use this box to type the initials of the user.
     
     
   • Last name   Use this box to type the last name of the user.
     
     
   • * Display name   Use this box to type a display name for the user. This is the name that's listed in the mailbox list in the EAC and in the shared address book. By default, this box is populated with the names you enter in the First name, Initials, and Last name boxes. If you didn't use those boxes, you must still type a name in this box because it’s required. The name can't exceed 64 characters.
     
     
   • * Name   Use this box to type a name for the user. This is the name that's listed in Active Directory. This box is also populated with the names you enter in the First name, Initials, and Last name boxes. If you didn't use those boxes, you must still type a name because this box is required. This name also can't exceed 64 characters.
     
     
   • Organizational unit   You can select an organizational unit (OU) other than the default (which is the recipient scope). If the recipient scope is set to the forest, the default value is set to the Users container in the Active Directory domain that contains the computer on which the EAC is running. If the recipient scope is set to a specific domain, the Users container in that domain is selected by default. If the recipient scope is set to a specific OU, that OU is selected by default.
     
     To select a different OU, click Browse. The dialog box displays all OUs in the forest that are within the specified scope. Select the desired OU, and then click OK.
     
     
   • * User logon name    Use this box to type the name that the user will use to sign in to the mailbox and to log on to the domain. The user logon name consists of a user name on the left side of the at (@) symbol and a suffix on the right side. Typically, the suffix is the domain name in which the user account resides.
     
     

     Note:
     If the value for the user name is different than the value used in the Alias box, then the user’s email address and the user logon name will be different.

   • * New Password   Use this box to type the password that the user must use to sign in to his or her mailbox.
     
     

     Note:
     Make sure that the password you supply complies with the password length, complexity, and history requirements of the domain in which you are creating the user account.

   • * Confirm password   Use this box to confirm the password that you typed in the Password box.
     
     
   • Require password change on next logon   Select this check box if you want the user to reset the password when they first sign in to the mailbox.
     
     If you select this check box, at first sign-in, the new user will be prompted with a dialog box in which to change the password. The user won't be allowed to perform any tasks until the password is successfully changed.
     
     
6. Click More options to configure the following boxes. Otherwise, skip to Step 7 to save the new user mailbox.
   
   
   • Specify the mailbox database   Use this option to specify a mailbox database instead of allowing Exchange to select a database for you. Click Browse to open the Select Mailbox Database dialog box. This dialog box lists all the mailbox databases in your Exchange organization. By default, the mailbox databases are sorted by name. You can also click the title of the corresponding column to sort the databases by server name or version. Select the mailbox database you want to use, and then click OK.
     
     
   • Create local archive storage for this user   Select this check box to create an archive mailbox for the mailbox. If you create an archive mailbox, mailbox items will be moved automatically from the primary mailbox to the archive, based on the default retention policy settings or those you define.
     
     Click Browse to select a database that resides in the local forest to store the archive mailbox.
     
     To learn more, see In-Place Archiving.
     
     
   • Address book policy   Use this option to specify an address book policy (ABP) for the mailbox. ABPs contain a global address list (GAL), an offline address book (OAB), a room list, and a set of address lists. When assigned to mailbox users, an ABP provides them with access to a customized GAL in Outlook and Outlook Web App. To learn more, see Address Book Policies.
     
     In the drop-down list, select the policy that you want associated with this mailbox.
     
     
7. When you're finished, click Save to create the mailbox.
   
   

This example creates a new user account and mailbox for Pilar Pinilla with the following details:

• The alias is pilarp
  
  
• The first name is Pilar and the last name is Pinilla
  
  
• The name and display name is Pilar Pinilla
  
  
• The user logon name is pilarp@contoso.com

This example creates a mailbox for the existing user estherv@contoso.com on the Exchange database named UsersMailboxDatabase.

	Copy Code
Enable-Mailbox estherv@contoso.com -Database UsersMailboxDatabase

You can also use the Enable-Mailbox cmdlet to mail-enable multiple users. You can do this by piping the results of the Get-User cmdlet to the Enable-Mailbox cmdlet. When you run the Get-User cmdlet, you must return only users that aren't already mail-enabled. To do this, you need to specify the value User with the RecipientTypeDetails parameter. You can also limit the results returned by using the Filter parameter to request only users that meet the criteria you specify. You then pipe the results to the Enable-Mailbox cmdlet.

For example, the following command mailbox-enables users who aren't already mail-enabled and that have a value in the UserPrincipalName property, which helps ensure that you don’t inadvertently convert a system account to a mailbox.

	Copy Code
Get-User -RecipientTypeDetails User -Filter { UserPrincipalName -ne $Null } | Enable-Mailbox

For syntax and parameter information, see Enable-Mailbox and Get-User.

For more information about pipelining, see Pipelining.

To verify that you’ve successfully created a mailbox for an existing user, do one of the following:

• In the EAC, navigate to Recipients  > Mailboxes. The new mailbox-enabled user is displayed in the mailbox list. Under Mailbox Type, the type is User.
  
  
• In the Shell, run the following command to display information about the new mailbox-enabled user.
  
  

  	Copy Code
  Get-Mailbox <Name> | FL Name,RecipientTypeDetails,PrimarySmtpAddress

  Note that value for the RecipientTypeDetails property is UserMailbox.
