How to Create a Mailbox for an Existing User
Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Applies to: Exchange Server 2007, Exchange Server 2007 SP1, Exchange Server 2007 SP2, Exchange Server 2007 SP3
This topic explains how to use the Exchange Management Console and the Exchange Management Shell to create a new mailbox for an existing user in Microsoft Exchange Server 2007. After you mailbox-enable an existing user on a specified Mailbox server, the user can send and receive e-mail messages.
Before You Begin
To perform this procedure, the account you use must be delegated the following:
Exchange Recipient Administrator role
Account Operator role for the applicable Active Directory containers
For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.
Important
If you want to create a new mailbox for a user that exists in a domain that is different than the one in which your Exchange servers reside, you must first prepare that domain for Exchange 2007. To learn more about preparing a domain for Exchange 2007, see How to Prepare Active Directory and Domains.
Procedure
Exchange 2007 Service Pack 1 (SP1)
To use the Exchange Management Console to mailbox-enable a user
In the Exchange Management Console, click Recipient Configuration.
In the action pane, click New Mailbox. The New Mailbox wizard appears.
On the Introduction page, click User Mailbox, and then click Next.
On the User Type page, click Existing user, and then click Browse.
In the Select User dialog box, select the user that you want to create a new mailbox for, and then click OK.
On the User Type page, click Next.
On the Mailbox Settings page, complete the following fields:
Alias By default, this field is populated based on the User logon name (User Principal Name) of the user if you are creating a mailbox for a single existing user. You can modify the alias in this field. If the user logon name contains any characters that are not valid for the alias field, they will be replaced by underscore characters (_). The alias cannot exceed 64 characters and must be unique in the forest. If you are creating mailboxes for multiple existing users, this text box will be unavailable and will display the following message: An alias will be automatically generated for each new mailbox.
Mailbox database 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 storage group name or server name. Select the mailbox database you want to use, and then click OK.
Managed folder mailbox policy To specify a messaging records management (MRM) policy, select this check box, and then click Browse to select the MRM mailbox policy to be associated with this mailbox. For example, use this option if you want this mailbox to adhere to an MRM policy such as the retention period for the mailbox data. To learn more about managed folder mailbox policies, see Understanding Messaging Records Management. This is an optional field.
Note
Managed custom folders are a premium feature of MRM. Mailboxes with policies that include managed custom folders require an Exchange Server Enterprise client access license (CAL).
Exchange ActiveSync mailbox policy To specify an Exchange ActiveSync mailbox policy, select this check box, and then click Browse to select the Exchange ActiveSync mailbox policy to be associated with this mailbox. To learn more about Exchange ActiveSync mailbox policies, see Understanding Exchange ActiveSync Mailbox Policies. This is an optional field.
On the New Mailbox page, review the Configuration Summary. This summary contains information about the options you have selected for the mailbox. To make changes to these options, click Back. To create the new mailbox, click New.
On the Completion page, the summary states whether the mailbox was successfully created and displays the Exchange Management Shell command that was used to create the mailbox.
Click Finish to create the mailbox for the user.

To create a new mailbox for the existing user John in the contoso.com domain, run the following command:
