This article describes several methods that you can use to connect Windows CE PC companion devices to Exchange Server. The easiest method uses a browser to connect to Exchange Server by using a Web interface. To use this method, the Outlook Web Access (OWA) component of Exchange Server must be installed on either the Exchange Server computer itself or on another computer. You can also connect to Exchange Server by using standard Internet protocols, such as Post Office Protocol version 3 (POP3) and Internet Message Access Protocol, Version 4rev1 (IMAP4).
This article does not describe third-party methods to connect Windows CE PC companion devices to Microsoft Exchange Server. This article only describes the "out of the box" solutions to connect these devices to Exchange Server. Also, this article does not describe how to synchronize your device by using a desktop personal computer; synchronize your device by using the software that is included with your device.
Connecting to Exchange Server By Using a Browser
Windows CE version 2.1 (Windows CE Pro) contains a browser that supports frames and scripting, as well as secure links and 128-bit security. This browser can connect to a standard OWA server and is the recommended method to connect devices that are running Windows CE 2.1 to Exchange Server. It requires the least amount of resources from the device that is running Windows CE. For more information about how to install OWA, see the Exchange Server 5.5 documentation.
Connecting to Exchange Server By Using POP3 or IMAP4
Windows CE 2.0 provides an Internet Mail Service (POP3 only) that you can configure to connect to Exchange Server.
IMPORTANT: This service can only make serial, dial-up, or infrared connections to the POP3 server. This service is not compatible with Ethernet network connections.
Windows CE 2.1 (Windows CE Pro) includes a POP3 service and an IMAP4 service. POP3 allows you to connect to only the Inbox; you cannot open any other folders. If you use the IMAP4 protocol, you can open folders other than the Inbox. Also, both of these protocols can use an Ethernet connection as well as serial, dial-up, or infrared connections.
Serial connections require that you have the Windows CE synchronization software and a connecting cable installed directly on the Exchange Server computer. Likewise, an infrared connection requires the Exchange Server computer to be fitted with a compatible infrared device. Serial and infrared connections also require the Exchange Server computer to be physically available to the Windows CE users. Because of these requirements, it is unlikely that a serial or infrared connection would be made from a Windows CE PC companion device directly to an Exchange Server computer. For more information about how to configure one of these types of connections, see the Windows CE help files on how to create the connection on the device.
A dial-up connection to the Exchange Server computer is the type of connection most likely to be used for remote connectivity. A compatible dial-up server must be configured either on the same computer that Exchange Server is installed on, or on another server that has connectivity to the Exchange Server computer. Microsoft Windows NT Remote Access Service (RAS) or Routing and Remote Access Service (RRAS) provide this capability.

An Ethernet connection is the fastest method available to connect Windows CE PC companion devices to Exchange Server. If you use a compatible Personal Computer Memory Card International Association (PCMCIA) card or CompactFlash Ethernet card with a device that is running Windows CE, you can make a direct connection to a desktop personal computer for synchronization. Handheld PCs that are running Windows CE Pro can also make POP3 or IMAP4 connections to Exchange Server computers that are available on the local area network (LAN). For more information about how to configure one of these types of connections, see the Windows CE help files about how to create the connection on the device. For additional information, refer to the FAQ located at the following Web site:
If you use any of these services with Exchange Server 5.5 you can connect directly to your server by using POP3 or IMAP4. However, to send mail by using SMTP, you must ensure that the server that you want to connect to has the Internet Mail Service configured and running. This can be a separate server, or the same server that contains your mailbox. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
