Configuring IMAP over SSL with SBS 2003 Premium and ISA 2004

Because of the release of the iPhone, there has been an increase in interest in configuring IMAP and POP3 services on SBS servers. In this author's opinion, providing access to e-mail via IMAP is better than POP3. The approach of IMAP more closely emulates how Exchange provides e-mail services in that messages are maintained on the server, and the IMAP client only pulls down what is needed. There are still security issues with IMAP, however, in that the default protocol still transmits the username and password information across the internet in clear text, and even though fewer sniffers are trained on IMAP ports to try and discover account credentials, the risk is still there.
To help protect account credentials, as well as e-mail contents, IMAP can be set up over SSL, which encrypts the entire transaction process, not just username and password. The iPhone and other devices can be easily set up to use IMAP over SSL, but you have to first set up the Exchange server on SBS to provide the secure mail transport. This document covers this implementation with SBS 2003 and ISA 2004. A separate document has been created for the process to follow with SBS 2003 Standard.

This document covers this implementation with SBS 2003 Standard and no ISA. You will need to configure your firewall to forward the appropriate ports to the SBS server, which is beyond the scope of this document.

Beginning in 2007, daylight saving time (DST) will be extended in the United States. DST will start on March 11, 2007, which is three weeks earlier than usual, and it will end on November 4, 2007, which is one week later than usual. This results in a new DST period that is four weeks longer than in previous years. Unless certain updates are applied to your computer, the time zone settings for your computer's system clock may be incorrect during this four-week period. In particular, you must make sure that both your Windows operating system and your calendar programs are updated.
Regarding the update for Exchange 2003 and SQL 2000, you can refer to the following detailed steps:
- Install the Windows OS update to the SBS 2003 server and all Windows 2003 servers on the network.(High-priority update on Windows Update and Microsoft Update on 2/13/2007). 931836 February 2007 cumulative time zone update for Microsoft Windows operating systems - http://support.microsoft.com/default.aspx?scid=kb;EN-US;931836
- Install the Windows OS update to all Windows XP/2003 clients on the network. (High-priority update on Windows Update and Microsoft Update on 2/13/2007). 931836 February 2007 cumulative time zone update for Microsoft Windows operating systems - http://support.microsoft.com/default.aspx?scid=kb;EN-US;931836

Exchange Calendar Update Tool
- Note 1: This tool must be run from a client that has been updated with 931836 with a user account that has full mailbox rights to all mailboxes. You should not run this tool on the SBS 2003 server. KB 930879 below provides a script to give a user full mailbox rights to all users. When you are done, you can run the script again to remove the full mailbox rights.
- Note 2: This tool requires the Outlook Time Zone Update Tool and .Net Framework 2.0 to be installed on the client computer.
- Note 3: This tool does not update public folders. The Outlook tool is the only way to update public folders.
- If users have a Windows Mobile device, the device will also need an update. See steps 3 and 4 here: http://www.microsoft.com/windowsmobile/daylightsaving/default.mspx#followsteps
