How to Enable Up-to-Date Notifications for Your Organization
After you configure your organization to use Microsoft® Exchange ActiveSync, you can configure your Exchange Server 2003 servers so that users can receive up-to-date notifications to keep their devices current with the changes that occur when a new item arrives in their Exchange mailbox. This notification prompts the user's device to synchronize with the Exchange mailbox automatically.
Procedure
To enable up-to-date notifications for your organization
On the Exchange front-end server running Exchange ActiveSync, log on with the Exchange administrator account, and then start Exchange System Manager.
Expand Global Settings, right-click Mobile Services, and then click Properties.
On the Mobile Services Properties page, in the Exchange ActiveSync pane, select Enable up-to-date notifications.
Click OK.
