There are two options available to prevent the Junk E-mail from being archived depending on the type of client being used, see options below.

Option 1: Using the Enterprise Vault Outlook Full Client

This can be configured via the Outlook application on the client machine:

1. Right-click on the Junk E-mail folder in Outlook
    
2. Select Properties.
    
3. Select the Enterprise Vault tab
    
4. Change the settings so that this folder is not archived.

 
Option 2: Using the Enterprise Vault Outlook Lite client

Use Enterprise Vault Policy Manager (EVPM) to run an EVPM script to disable archiving for the junk e-mail folder . 

1. Create a initialization file. This should be a text file (an example of the content is included at the end of this document)
    
2. Include the Distinguished Names of all the mailboxes which require the archiving of the "Junk E-mail" folder disabled.
    
3. Save the text file in Unicode format with a .ini extension.
    
4. Run EVPM on the EV server:
   
   a.    Click on Start > Run
   
   b.    Type cmd and click OK
   
   c.    Change to the Enterprise Vault installation folder.  e.g.  c:\Program Files (x86)\Enterprise Vault
   
   d.    Run the following command:
   
   evpm
   
   Example :
   
   evpm myexchange EnterpriseVault-myexchange c:\Program Files (x86)\enterprise vault\evpm_junk.ini
   
   Example .ini file:
   
   [Directory]
   DirectoryComputername =
   SiteName =
   
   [Mailbox]
   DistinguishedName = /o=organization/ou=mailboxou/cn=Recipients/cn=
   
   [Folder]
   Name = \Junk E-Mail
   Filtername = DoNotArchive
   OverrideArchiveLocks = true
    

Note: For some special folders created by Outlook, it is not required to specify a path. Only the folder name needs to be specified without the backslash. These special folders are: Inbox, Outbox, SentItems, DeletedItems, Drafts, Calendar, Contacts, Journal, Notes, Tasks. These names work for all languages. For example, it can be specified Inbox on a Japanese system. Additionally, the [Folder] part must be added for each folder specified in the script.
