When using MessageGuard with Exchange, you first need to configure Exchange to perform "journaling" on the messages going through the Exchange system.

MessageGuard, Exchange 2000 SP3, Exchange 2003 SP1.

Before you can proceed, your Microsoft Exchange server must be on a version that supports Envelope Journaling.  You must be on (at least) Exchange 2000 SP3 with the August 2004 Update Rollup, Exchange 2003 SP1 (or newer), Exchange 2007, or Exchange 2010.  The updates for Exchange 2000 SP3 are located at http://support.microsoft.com/kb/870540/.

On Exchange 2000 and 2003, it supported two different forms of journaling.  We need the more detailed type called Envelope Journaling.  To activate this, you use the "exejcfg.exe" tool, located at http://www.microsoft.com/downloads/details.aspx?FamilyId=E7F73F10-7933-40F3-B07E-EBF38DF3400D&displaylang=en .  Download this tool on a Domain Controller...we'll use it in a moment.

1. Make an account for the journaling ("messageguard" for example).  This account needs to have a very secure / strong password, since every piece of mail will be temporarily stored in this mailbox.  We recommend using at least one special character, one number, and mixed case.  A random string of characters works best.
2. Find the server mailbox store in System Manager (Administrative Groups -> Group -> Servers -> Server Name -> Storage Group), right click the Mailbox Store and go to Properties.
   • Check the box for "Archive all messages sent or received by mailboxes on this store"
   • Click on the Browse button and find the messageguard account that was just created
3. On a domain controller, run the exejcfg.exe at a command prompt with the -e option to enable envelope journaling... "exejcfg.exe -e".
4. Make sure POP3 is enabled for the server. (Administrative Groups -> Group -> Servers -> Server Name -> Protocols -> POP3 -> Default POP3 Virtual Server) (This may be off in the Services applet in the Control Panel too...check to make sure it's not disabled there. If it is, set it to Automatic). If you'd like to only allow POP3 access for the purpose of MessageGuard archiving, you can restrict access to the POP3 service on the Access tab to just the appliance's IP address.

Once you've completed the above steps, call customer service at 877-225-0100 and we'll finish the setup process with you and test to make sure mail is getting routed correctly.
