Always-up-to-date Notifications is a new feature in Exchange 2003 that permits an always up-to-date user experience with Pocket PC. This feature is only available on devices that have Microsoft Windows Mobile 2003 operating system. By default, Always-up-to-date Notifications are installed with Exchange 2003. When an event is generated in a user’s Exchange account, a notification is sent to the user’s device. The device performs synchronization in the background so that the most current information is available when the user next checks the device.
When a message arrives in the user’s mailbox, there is an event registration item in this folder (referred to as a binding) that is registered with the Exchange OLE Database Provider (ExOLEDB) and the Exchange Store Event .dll file (OmaSink.dll). The binding will trigger an event with the store event sink (OmaSink). The store event sink creates a new message in the Simple Mail Transfer Protocol (SMTP) Pickup directory. The message is then processed by the Outlook Mobile Access Categorizer. The Outlook Mobile Access Categorizer modifies the message body and adds the user’s device address as the recipient. Exchange 2003 can then send the SMTP message to the appropriate carrier by using the standard routing mechanism. The carrier creates and sends a Short Messaging Service message to the device.
