You can turn Message Archiving on or off at any time, as follows:

1. Access the Administration Console:
   
   1. Sign in to the Google Admin console. 
   2. On the dashboard, click Postini services.
   3. Click System Administration.
   
   
2. Go to Orgs and Users > Orgs, and then select the users organization for which you want to turn on archiving. For example:



3. On the Organization Management page, scroll down to Organization Settings, then click Archiving:



4. Under Message Archiving Settings, select or clear the Archive messages for this organization check box.


5. If you are turning on archiving:
   • Google Apps Message Discovery: Ensure that All inbound & outbound messages is selected. Don't select All journaled messages, because that option does not apply to your service.
   • Google Message Discovery: Select either All inbound & outbound messages or All journaled messages. If you select both options, Message Archiving stores two copies of all inbound and outbound messages.

To ensure that all your users' email messages are archived, do the following:

• Keep the Non-Account Bouncing option set to OFF for your Message Discovery service. When on, this option tells your service to reject any messages sent to an account that isn't registered with the service. In this case, if you add a new user account to Google Apps, that user won't receive message and the user's messages won't be archived until the account is synchronized on your Message Discovery service. To check the Non-Account Bouncing setting, go to Orgs and Users, and then select the relevant users organization. Select General Settings.
• Make sure you've added all your subdomains to Google Apps as domain aliases. If any users have subdomain email addresses, their messages are archived only if you've added the subdomain to Google Apps and changed your MX records so that messages for the subdomain flow through your Message Discovery service. Usually, it's best to add all of your subdomains during activation of the service. For details, see Step 3 of the Postini for Google Apps Activation Guide.

Email Settings in Google Apps includes the Route to catch-all address option, which is turned off by default. If on, this option routes any email messages sent to unknown users in your domain (for example, unknown@yourdomain.com) to the user account you specify. We recommend that you keep this option turned off; otherwise, spammers can send messages to nonexistent addresses in your domain, and because Google Apps will accept these messages, Message Discovery will archive them.

If you want to archive messages for some users and not others, you can use the Message Discovery Administration Console to group those users into separate user organizations. Then turn on archiving for the organization whose messages you want to archive, and leave if off for the organization whose messages you don't want to archive.

You can let other users have complete access to all messages in the archive. We recommend that you let at least one other user have this access.

The Personal Archive is a component of the Message Center. It lets users recover their own archived messages in the event that they delete them from their mail accounts. By default, users can access their Personal Archives. To prevent access, you can remove their Personal Archive privileges.
