This topic explains how to create an external host name for Outlook Anywhere on a computer that is running Microsoft Exchange Server 2007 that has the Client Access server role installed.
If you manage more than one Exchange site, we recommend that you create separate external host names for each site that has a Client Access server that is enabled for Outlook Anywhere. When you create separate external host names for each site, Microsoft Office Outlook 2007 clients automatically use the Client Access server that is closest to their mailbox.
|For Outlook 2007 clients to be able to automatically use the Client Access server that is closest to their mailbox, the user's mailbox must be located on either an Exchange 2003 server that has Service Pack 1 (SP1) or later versions installed or on an Exchange 2007 server that has the Mailbox server role installed.|
|Users who are using Outlook 2003 must have their profiles manually updated to use the external host name that is closest to their mailbox.|
To perform this procedure, the account you use must be delegated the Exchange Organization Administrator role.
For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
|To successfully complete this procedure, either the Client Access server must be enabled for Outlook Anywhere or the external host name must be specified by using the Enable Outlook Anywhere Wizard.|
In the console tree, expand Server Configuration, and then click Client Access.
In the action pane, click Properties for the Client Access server.
On the Client Access server properties page, click the Outlook Anywhere tab.
In the text box under External host name, enter the external host name to use for this site.
Click OK to save your changes.
Run the following command:
set-OutlookAnywhere -Server:'CAS01' -ExternalHostName:'site.contoso.com'
