Microsoft Exchange Server, E-mail, and Remote Access

No. Exchange Server 2007 is only available as a 64-bit product; it cannot be installed on a 32-bit operating system such as SBS 2003 R2.

Yes. However, the SBS 2003 R2 configuration wizards and management tools will not work with Exchange Server 2007, and so you must manually configure and monitor both Exchange Servers so that they will operate properly in your domain. For more information on configuring multiple Exchange Servers in a domain, consult the Exchange Server 2007 online help.

No. You must purchase additional Exchange Server 2007 CALs in order to be compliant with your licenses.

Yes. Your SBS 2003 R2 CAL entitles each user or device to use Outlook 2003 or any earlier version to connect to the Exchange Server 2003 technology in SBS 2003 R2.

Yes. The Microsoft Connector for POP3 Mailboxes is included with both SBS 2003 R2 Standard Edition and Premium Edition.”

Many small businesses that purchase SBS 2003 R2 already use pre-existing POP3 mailbox accounts. After these businesses configure Exchange technology for e-mail services, they need a way to transition from their old e-mail addresses based on POP3 to their new addresses based on the Simple Mail Transfer Protocol (SMTP). The Microsoft Connector for POP3 Mailboxes provides an easy way to continuously retrieve e-mail sent to pre-existing e-mail addresses and deliver it to the new SMTP ones. Users can now view all of their mail from a single, integrated Inbox in Outlook 2003. Use of the POP3 connector also assists in better filtering for unsolicited e-mail because message delivery is controlled by the Exchange server, not by client computers.

SBS 2003 R2 does not automatically create shortcuts on the user's desktop for the Company and User folders. This is a change from Small Business Server 2000, and it was made to accommodate customer requests for an uncluttered desktop.

Because of the way that IIS, Exchange, and OWA are integrated and managed on SBS 2003 R2, you cannot do this. If you want to run OWA on a separate physical server, you must purchase an additional copy of Exchange Server 2003 Standard Edition. This means that Exchange and OWA will not be managed using SBS 2003 R2 management consoles and your e-mail accounts and functionality must be managed separately.

Yes. An employee’s computer must be left on in order to gain remote access to the desktop.

SBS 2003 R2 Backup cannot be used to restore individual e-mail messages or files from user mailboxes. SBS 2003 R2 Backup functionality is designed to backup user data and shared data files stored on the server. However, SBS 2003 R2 does store deleted e-mail messages and files on the server for a period of time so an end user can restore them without assistance from the person responsible for the network. For more information, see "Recover deleted items or folders that were permanently deleted" in Outlook 2003 Help.

No. The option to use "Outlook over the Internet" enables RPC over HTTP in SBS 2003 R2. RPC over HTTP is a new feature in Exchange Server 2003 and in Outlook 2003. Using RPC over HTTP, remote users can enjoy the full Outlook client experience without the need to first establish a virtual private network (VPN) connection. RPC over HTTP wraps the original RPC commands from Outlook into the HTTP protocol, then encrypts them using Secure Sockets Layer (SSL), so all traffic between the remote client and the server occurs over SSL/HTTPS. RPC ports are not exposed to the Internet when using this feature. For more information about RPC over HTTP, see Configuring Outlook 2003 for RPC over HTTP on the Office Online Web site.

No. You can use this feature to connect only to computers running Windows XP Professional or later.

WebEx is primarily a remote conferencing product, while Go2MyPC is a remote access product. A quick glance at the Web sites shows a key differentiator: Go2MyPC chargez for remote access, typically a per-user-per-month fee. For SBS 2003 R2, access to your desktop via Remote Web Workplace is included for free with your Client Access Licenses. Cost-sensitive businesses may find that third-party access solutions are not cost-effective for multiple employees. In addition, these solutions do not provide the automatic backup of user information stored in the “My Documents” folder, the ability to access network applications and resources, or have immediate access to information that others have shared on the network. In sum, these may be sufficient for individual or home users but it is not the smartest, cost-effective solution for businesses.

The first time that your internal company Web site is launched, the Internet Information Services (IIS) World Wide Web worker process must start (usually 10-20 seconds). Subsequent requests are processed immediately because the process has already started. If the internal site is not accessed for an extended period of time (the default is 11 hours), the same delay will occur the next time the site is accessed. You can use the IIS Manager snap-in to modify the timeout period.

A static IP address is not required on the client to use the "Connect to my computer at work" feature of the Remote Web Workplace. In fact, Microsoft recommends that client computers be configured to use the DHCP Server service to dynamically assign IP addresses and avoid potential IP conflicts on the local network. Currently, only SBS 2003 with Service Pack 1 and SBS 2003 R2 provide this functionality for Remote Web Workplace.

In order for the files to be synchronized, the laptop must be connected to the domain. If the laptop is not connected to the domain, a notification appears in the system tray announcing that the server cannot be contacted. In that case, updated files are stored on the local hard disk drive. The next time the laptop is connected to the domain, the files on the laptop and the server are synchronized. If you connect to the network over a slow connection, such as a dial-up, the files are not synchronized.

SBS 2003 R2 configures connectivity for your Windows Mobile-based Smartphone or Pocket PC Phone Edition when the device connects to a client computer within the network. Once configured, the device can be synchronized with the server in any wireless environment. Users can send and receive e-mail, and manage contacts and calendar items as if they were sitting at their desktop computer. You can learn how to configure SBS and your wireless devices for remote e-mail access on the Microsoft Web site.

Yes. For security purposes, you must install a certificate on your mobile device in order to access the SBS 2003 R2 network. You can use a self-signed certificate or obtain a certificate from a trusted third-party provider. For more information on setting up mobile connections and configuring certificates, see the whitepaper “Deploying Windows Mobile 5.0 with Windows SBS 2003” at the Microsoft Web site.
