      The Display name field (located on the General tab) can contain Unicode characters. However, third-party applications and older client applications may not support Unicode characters. If the system that is displaying the public folder doesn't support Unicode characters, the simple display name can be used. For more information about Unicode characters, see Unicode.
      
      
    • 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.

11. (This tab appears only for mail-enabled public folders.)
    
    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.
      
      
    •    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.
      
      
12. (This tab appears only for mail-enabled public folders.)
    
    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.
    
    
13. (This tab appears only for mail-enabled public folders.)
    
    Use the Mail Flow Settings tab to configure delivery options and message size or message delivery restrictions for the mail-enabled public folder.

      Deliver message to both forwarding address and mailbox   If you selected the Forward to check box, you can select this check box to specify that e-mail messages be delivered to both the public folder and to the forwarding address.
      
      
    • Message Size Restrictions Select this setting and then click Properties to open the Message Size Restrictions dialog box. In this dialog box, use the Maximum message size (in KB) check boxes to set the maximum size for messages that can be sent and received by this recipient. Use the corresponding text boxes to type 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.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Public folders" entry in the Mailbox Permissions topic.

Use the Set-MailPublicFolder cmdlet to configure public folder properties.

This example sets the primary SMTP address of the public folder Sales to MyMailPublicFolder@contoso.com.

	Copy Code
Set-MailPublicFolder -Identity "\Sales" -PrimarySmtpAddress MyMailPublicFolder@contoso.com

Note:
You cannot change the primary SMTP e-mail address if the EmailAddressEnabled parameter is set to true.

This example disables the e-mail address policy of the mail-enabled public folder Sales.

	Copy Code
Set-MailPublicFolder -Identity "\Sales" -EmailAddressEnabled $False

This example assigns a value (string) to the first custom attribute of the mail-enabled public folder Sales.

	Copy Code
Set-MailPublicFolder -Identity "\Sales" -CustomAttribute1 "This string is the value of custom attribute one."

This example sets a 200 megabyte (MB) size limit for the mail-enabled public folder Sales, after which the folder can no longer send e-mail messages.

	Copy Code
Set-MailPublicFolder -Identity "\Sales" -SendStorageQuota 200MB
