  In Exchange 2007, the Display name field can contain Unicode characters. Third-party applications and older client applications may not support Unicode characters. If the system that is displaying the public folder does not support Unicode characters, the simple display name can be used. For more information about Unicode characters, see Unicode.

Use the E-Mail Addresses tab to configure the e-mail addresses for the mail-enabled public folder. You can modify the existing addresses or create additional addresses. Each mail-enabled public folder must have at least one primary Simple Mail Transfer Protocol (SMTP) address.

Note:
By default, each mail-enabled public folder has e-mail addresses based on the e-mail address policies that are defined in your Exchange organization. For more information about e-mail address policies, see Managing E-Mail Address Policies.

The following fields are available:

• Add   Click this button to add a new e-mail address for this mail-enabled public folder. Use the drop-down box to select an SMTP e-mail address (default) or a custom e-mail address. Depending on the type of address you select, the SMTP E-Mail Address or the Custom Address dialog box appears.
  In Exchange 2007, all addresses that are not SMTP addresses are considered to be custom addresses. Exchange 2007 does not provide unique dialog boxes or property pages for X400, GroupWise, or Lotus Notes e-mail address types.
  If you add a custom address, you must have appropriate dynamic-link library (DLL) files installed. If you do not have the appropriate DLL files, you are not able to create a customized e-mail address policy. The following error is logged in Event Viewer:
  "The e-mail address description object in the Microsoft Exchange directory for the 'Address Type' address type on 'Machine Type' machines is missing."
  
• Edit   Click this button to modify the selected e-mail address. Depending on the type of address you select, the SMTP E-Mail Address or the Custom Address dialog box appears.
  
•    Click this button to delete the selected e-mail address.
  

  Note:
  You cannot use this button to remove the primary SMTP address for a recipient. To remove a primary SMTP address, you must first designate a new or existing SMTP address as primary.

• Set as Reply   Click this button to set your selected address as the reply to address. When the mail-enabled public folder sends an e-mail message, this is the e-mail address that is seen by other users and is the address to which they reply.
  A mail-enabled public folder can have multiple e-mail addresses for a specific address type. This allows the mail-enabled public folder to receive messages that are addressed to any one of these e-mail addresses. However, a single address must be designated as the reply to address for each address type. An e-mail address that is designated as the reply to address is also considered the primary address for the specific address type.
  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.
  

  Note:
  If an e-mail address policy in your Exchange organization applies to this mailbox, the Set as Reply setting is 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.

Automatically update e-mail addresses based on e-mail address policy   Select this check box to have the mail-enabled public folder's e-mail addresses automatically updated based on changes made to e-mail address policies in your organization. This box is selected by default.

Use the Member Of tab to view a list of distribution groups that includes this mail-enabled public folder. You cannot use this tab to modify membership information. To add this mail-enabled public folder to a distribution group or to remove it from a distribution group, you must use the property pages of that distribution group. For more information about how to create or delete distribution groups, see Managing Distribution Groups.

Note:
The public folder may match the criteria for one or more dynamic distribution groups in your organization. However, dynamic distribution groups are not displayed on this tab because their membership is calculated each time they are used.

Note:
This tab displays all groups that include this public folder, some of which may not be mail-enabled. Mail-enabled groups have an envelope icon next to them.

The following fields are available:

• Display Name   Displays the name of the group.
  
• Organizational Unit   Displays the organizational unit (OU) that contains the group.
