Hi RickyHere are the steps if you still need it: Creating and Applying New Address Lists You can create new address lists to accommodate your organization's special needs. For example, if your organization has offices in Seattle, Portland, and San Francisco, you might want to create separate address lists for each office. To create an address list that users can select in their Outlook mail client, follow these steps: In Exchange Management Console, expand the Organization Configuration node, and then select the related Mailbox node. Right-click the Mailbox node in the console tree, and then select New Address List. This starts the New Address List wizard. type a name for the address list. The name should describe the types of recipients that are viewed through the list. For example, if you're creating a list for recipients in the Boston office, you could call the list Boston E-mail Addresses. The container on which you base the address list sets the scope of the list. The list will include recipients in address lists in and below the specified container. The default (root) container, , specifies that all address lists are included by default. To specify a different container for limiting the list scope, click Browse, and then use the Select Address List dialog box to select a container. In most cases, you'll want to select the default (root) container. Use the Include These Recipient Types options to specify the types of recipients to include in the query. Select either All Recipient Types or select The Following Specific Types, and then select the types of recipients. Click Next. On the Conditions page, you can now set the filter conditions. The following types of conditions are available: q Recipient Is In A State Or Province Filters recipients to be included in the address list based on the value of the State/Province field on the Address And Phone tab in the related Properties dialog box. Click the related In The Specified State Or Province link. In the Specify State Or Province dialog box, type a state or province to use as a filter condition, and then press Enter or click Add. Repeat as necessary, and then click OK. q Recipient Is In A Department Filters recipients to be included in the address list based on the value of the Department field on the Organization tab in the related Properties dialog box. Click the related In The Specified Department link. In the Specify Department dialog box, type a department to use as a filter condition, and then press Enter or click Add. Repeat as necessary, and then click OK. q Recipient Is In A Company Filters recipients to be included in the address list based on the value of the Company field on the Organization tab in the related Properties dialog box. Click the related In The Specified Company link. In the Specify Company dialog box, type a company name to use as a filter condition, and then press Enter or click Add. Repeat as necessary, and then click OK. Click Next. If you want to create and apply the address list immediately, select Immediately. To schedule the address list creation and application, select At The Following Time, and then set the date and time to create and apply the list. To specify the maximum length of time that the server can spend creating and applying the address list, select the Cancel Tasks That Are Still Running After (Hours) check box, and then set the maximum number of hours the address list task can run. Note Cancelling after a maximum number of hours is designed to ensure address list tasks that are blocked or not proceeding as expected are cancelled. Most address list tasks should be completed in two hours or less, but the exact duration depends on the number of recipients involved and the complexity of the filters. Click Next, and then click New to create and schedule the address list to be created. After the address list is created, users will be able to use the new address list the next time they start Microsoft Outlook. Click Finish.hopefully this is just what you've been looking for.
