As is also the case with the user permissions, you can confi gure administrative permissions using
the Exchange 2003 System Manager. You do so by following these steps:
1. On the respective Exchange 2003 Server, open the System Manager by clicking
Start | All Programs | Microsoft Exchange | Exchange System Manager.
2. Drill down to the Folders and expand the Public Folders node.
3. Now right-click the Public Folder for which you want to add or remove administrative
permissions, then select Properties.
4. Click the Permissions tab.
5. Click the Administrative Rights button. Here you can see each user that has already
been granted permissions to administer the Public Folder.
6. Click Add and add the respective user(s) to the administrative permission list (see Figure 4.23),
then click OK.

7. Now select the user(s) you just added, then grant the type of administrative permission
you want the user to have. You do so by ticking the respective permission boxes under
Permissions for Administrator.
8. Finally, click OK and exit the Exchange 2003 System Manager.
Managing Public Folder Replica Settings
Another feature missing in the Exchange 2007 Management Console is the option of confi guring
Public Folder replication settings. This also has to be done using either the EMS or an Exchange 2003
server that’s still part of your Exchange organization.
To stop or resume Public Folder replication, you can use the Stop-PublicFolderReplication and
Resume-PublicFolderReplication CMDlets, respectively.
To add Public Folder databases to or remove them from a replica list, you’ll need to use the
an Exchange 2003 System Manager.
Mail-Enabling a Public Folder
You might run into situations where you want to mail-enable a Public Folder—perhaps you’ll want
your users to be able to send messages to the folder in addition to posting messages. Because
Public Folders by default are not mail-enabled, you need to mail-enable them using either the

Enable-MailPublicFolder CMDlet or an Exchange 2003 System Manager. To mail-enable the Finance
Public Folder we created earlier using the Enable-MailPublicFolder CMDlet, we would need to type:
Enable-MailPublicFolder -Identity “\Finance” followed by Enter
If you don’t want the Public Folder to appear in the GAL, you would need to include the
HiddenFromAddressListsEnabled parameter, and the command would look like the following:
Enable-MailPublicFolder -Identity “\Finance” -HiddenFromAddressListsEnabled
followed by pressing Enter.
NOTE
You need to create a Public Folder before you can mail-enable it.
To get a list of the mail-enabled Public Folders in your organization, you can use the
Get-MailPublicFolder CMDlet. To get information for a specifi c mail-enabled Public Folder,
type Get-MailPublicFolder –Identity <public_folder>.
Managing the Exchange 2007 Mailbox Server Role • Chapter 4 189
If you don’t specify an SMTP address when you mail-enable a Public Folder, it will use the name
of the Public Folder. So, if the Public Folder is called Finance and the domain is Exchangedogfood.dk,
the address will be fi If you want to use another primary SMTP address,
you need to set it using the Set-MailPublicFolder CMDlet. The command would then be:
Set-MailPublicFolder -Identity “\Finance” -PrimarySmtpAddress:

followed by pressing Enter.
Many other Set-MailPublicFolder CMDlet parameters are available. We won’t go into details on
each of them, but instead we list each of them with a short description in Table 4.4.
