Mail users are similar to mail contacts. Both have external e-mail addresses and both contain information about people outside your Exchange organization that can be displayed in the global address list (GAL) and other address lists. However, unlike a mail contact, a mail user has Active Directory logon credentials and can access resources.

Properties specific to a mail user are controlled by the Set-MailUser cmdlet. You can use the EMC to set additional properties, but the permissions may vary depending upon the feature that you're configuring.

What Do You Want to Do?

Use the EMC to configure mail user properties

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Provisioning Recipient Permissions" section in the Mailbox Permissions topic.

  1. In the console tree, navigate to Recipient Configuration > Mail Contact.

  2. In the result pane, select the mail user that you want to configure.

  3. In the action pane, click Properties.

  4. Use the General tab to modify the display name, alias, and custom attributes.

    • Display name   Use this unlabeled box at the top of the page to view or change the display name.

    • Organizational unit   This field displays the organizational unit (OU) that contains the user account.

    • Modified   This read-only field displays the last date and time that a configuration change was made to the recipient.

      Configuration changes made through any other method, such as the through the Exchange Management Shell or Active Directory Service Interfaces (ADSI) Edit, will also update this field.

    • Alias   Use this box to view or change the recipient's alias. The alias can't exceed 64 characters and must be unique in the forest. One of the reasons why the alias field must be unique is because it's used to generate the SMTP address in a default installation.

    • Use MAPI rich text format   Select one of the following options from the corresponding list:

      Never   If you select this option, messages sent to this recipient will be converted to plain text.

      Always   If you select this option, messages sent to this recipient will be in the MAPI rich text format (RTF).

      Use Default Settings   If you select this option, messages sent to this recipient will be sent in either MAPI RTF or plain text, depending on the settings of the client computer from which the message is sent.

    • Hide from Exchange address lists   Select this check box to prevent the recipient from appearing in the global address list (GAL) and other address lists that are defined in your Exchange organization.

      After you select this check box, users in your Exchange organization can still send messages to the recipient by using the e-mail address.

    • Custom Attributes   Click this button to open the Custom Attributes dialog box. You can specify up to 15 custom attributes for the recipient. To specify the custom attribute values, use the corresponding boxes, and then click OK.

  5. Use the User Information tab to modify the following fields.

    • First name   Use this box to modify the recipient's first name.

    • Initials   Use this box to modify the recipient's middle initials.

    • Last name   Use this box to modify the recipient's last name.

    • Name   Use this box to modify the recipient's directory name. This is the name that's listed in Active Directory.

    • Simple display name   Use this box to modify the recipient's simple display name. The simple display name field accepts only ASCII characters.

      In Exchange 2010, the Display name field (located on the General tab) can contain Unicode characters. However, third-party applications and older clients may not support Unicode characters. If the system that is displaying the recipient properties doesn't support Unicode characters, you can use the simple display name. For more information about Unicode characters, see Unicode.

    • Web page   Use this box to modify the recipient's Web page address.

    • Notes   Use this box to modify administrative notes about the recipient.

      These notes are also visible in Outlook. When a user views the recipient's properties in Outlook, the notes will be displayed on the Phone/Notes tab.

  6. Use the Address and Phone tab to view or modify the following fields:

    • Street address   Use this box to view or change the recipient's street.

    • City   Use this box to view or change the city where the recipient is located.

    • State/Province   Use this box to view or change the state or province where the recipient is located.

      You can use the State/Province field as a condition for dynamic distribution groups and e-mail address policies. If you plan to use this field as a condition, you must devise and follow a consistent naming convention to ensure accurate results for dynamic distribution groups and e-mail address policies.

    • ZIP/Postal code   Use this box to view or change the ZIP code or the postal code where the recipient is located.

    • Country/region   Use this list to view or change the country or region where the recipient is located.

  7. Use the Organization tab to view or change the information about the recipient's role in your organization.

    • Title   Use this box to view or change the recipient's title.

    • Company   Use this box to view or change the company for which the recipient works. You can use this field to create recipient conditions for dynamic distribution groups, e-mail address policies, or address lists.

    • Department   Use this box to view or change the department in which the recipient works. You can use this field to create recipient conditions for dynamic distribution groups, e-mail address policies, or address lists.

    • Office   Use this box to view or change the office location for the recipient.

    • Manager   Select this check box if you want to specify this recipient's manager. By specifying the manager for each recipient in your organization, you can create a virtual organization chart that is accessible from e-mail clients such as Outlook.

      Click Browse to open the Select Recipient User or Contact dialog box. Select the recipient's manager, and then click OK to return to the property page.

    • Direct Reports   Use this box to view the list of mailbox users and contacts that are managed by this recipient. This field is read-only and is populated automatically when this recipient is designated as a manager for another recipient.

  8. Use the Account tab to modify the logon names for the Active Directory domain service user account that is associated with the recipient:

    • User logon name (User Principal Name)   The user logon name consists of a user name and a suffix. Use this box to type the user name that the user will use to log on to the Active Directory domain. The user logon name cannot exceed 1,024 characters and must be unique in the forest.

      Use the corresponding drop-down list to select the suffix for this user. Typically, the suffix is the Active Directory domain name in which the user account resides. To view or change the list of available domain suffixes in your forest, use Active Directory Domains and Trusts. In the Active Directory Domains and Trusts console tree, right-click Active Directory Domains and Trusts, and then click Properties. In the property page, use the UPN suffixes tab to view the list of available domain suffixes in the forest.

    • User logon name (pre-Windows 2000)   Use this box to type a user name that is compatible with legacy versions of Windows (prior to the release of Windows 2000 Server). The user logon name for a version of Windows earlier than Windows 2000 Server can't exceed 20 characters and can't contain any of the following characters: \/ [] : | <> + = ; ? , *.

      When the user account is first created, this field is automatically populated based on the User logon name (User Principal Name) field.

    • User must change password at next logon   Select this check box if you want the user to change the password at next logon. The user won't be able to log on until the password is successfully changed.

  9. Use the Member Of tab to view a list of the groups to which this recipient belongs. Some of these groups may not be mail-enabled. Mail-enabled groups will have an envelope icon next to them. You can't use this tab to modify membership information. The recipient may match the criteria for one or more dynamic distribution groups in your organization. However, dynamic distribution groups aren't displayed on this tab because their membership is calculated each time they are used. For more information, see Managing Distribution Groups.

  10. Use the E-Mail Addresses tab to configure the e-mail addresses for the recipient. You can modify the existing addresses or create additional ones. Each recipient must have at least one primary STMP address that is internal to your Exchange organization and one external address.

    • Add   Click Add to add a new e-mail address for this recipient. Use the drop-down box to select from the following address types:

      SMTP Address   This is the default address type. Click this button and use the corresponding dialog box to add an SMTP address.

      EUM Address   This address type is available only for user mailboxes. It's not available for mail users, mail contacts, distribution groups, or mail-enabled public folders. An EUM (Exchange Unified Messaging) address is used by Unified Messaging servers to locate UM-enabled users within an Exchange 2010 organization. EUM addresses contain the extension number and the UM dial plan for the UM-enabled user. Click this button and use the corresponding dialog box to add an EUM address.

      Custom Address   Click this button and use the corresponding dialog box to add a custom address (for example, fax or X.400).

      Note:
      With the exception of X.400 addresses, Exchange doesn't validate custom addresses for proper formatting. You must make sure that the custom address you specify complies with the format requirements for that address type.
    • Edit   Click this button to modify the selected e-mail address.

    • Remove icon   Click this button to remove the selected e-mail address.

    • Set as Reply   Click this button to set your selected address as the "reply to" address. A recipient can have multiple e-mail addresses for a specific address type. This allows the recipient to receive messages that are addressed to any one of these e-mail addresses. However, a single address must be used for any messages that are sent by the recipient. If a recipient has multiple e-mail addresses, the primary address is used for any messages sent by the recipient.

      This button is available only when an address other than the primary address is selected. Primary addresses for each address type are displayed in bold type.

      If an e-mail address policy in your Exchange organization applies to this mailbox, the Set as Reply setting will be controlled by that policy. To change the primary address for a specific address type, you must clear the Automatically update e-mail addresses based on e-mail address policy check box.

    • Set as External   This button is available only for mail users and mail contacts. It's not available for user mailboxes, distribution groups, or mail-enabled public folders. Click Set as External to designate the selected e-mail address as the external e-mail address for the recipient.

      Note:
      This button is enabled when an address other than the external e-mail address is selected.
    • Automatically update e-mail addresses based on e-mail address policy   Select this check box to have the recipient's e-mail addresses automatically updated based on changes made to e-mail address policies in your organization. This box is selected by default.

  11. Use the Mail Flow Settings tab to configure message size or message delivery restrictions for the mail user.

    • Message Size Restrictions Select this setting and then click Properties to open the Message Size Restrictions dialog box. In this dialog box, select the Maximum message size (in KB) check box to set the maximum size for messages that can be received by this recipient. Use the corresponding text box to specify the maximum message size allowed (in KB). The message size must be between 0 and 2,097,151 KB. If a message larger than the specified size is sent to the recipient, the message will be returned to the sender with a descriptive error message.

    • Message Delivery Restrictions   Select this setting and then click Properties to open the Message Delivery Restrictions dialog box. Use this dialog box to configure the following settings:

      All senders   Click this button to specify that the recipient can accept messages from all senders. This includes senders in both your Exchange organization and external senders. This button is selected by default. This option includes external users only if you clear the Require that all senders are authenticated check box. If you select this check box, messages from external users will be rejected.

      Only senders in the following list   Click this button to specify that the recipient can accept messages only from a specified set of senders in your Exchange organization. Click Add to open the Select Recipient dialog box. This dialog box displays a list of all recipients in the Active Directory forest. Select the recipients you want, and then click OK. You can also search for a specific recipient by typing its name in the Search box and then clicking Find Now.

      Require that all senders are authenticated   Select this check box to prevent anonymous users from sending messages to the recipient.

      No senders   Click this button to specify that the recipient will not reject messages from any senders in the Exchange organization. This button is selected by default.

      Senders in the following list   Click this button to specify that the recipient will reject messages from a specified set of senders in your Exchange organization. Click Add to open the Select Recipient dialog box. This dialog box displays a list of all recipients in the Active Directory forest. Select the recipients you want, and then click OK. You can also search for a specific recipient by typing its name in the Search box and then clicking Find Now.

Use the Shell to configure mail user properties

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Provisioning Recipient Permissions" section in the Mailbox Permissions topic.

This example sets the e-mail address outside of the organization to which mail-enabled user John Peoples' e-mail is sent.

Copy Code
Set-MailUser john -ExternalEmailAddress john@tailspintoys.com

This example sets the maximum size of messages that John Peoples is allowed to receive to 10 MB.

Copy Code
Set-MailUser -Identity john -MaxReceiveSize '10 MB'
