In Microsoft Office Outlook 2007, retention settings and AutoArchive help determine how e-mail is managed in user mailboxes. You can configure settings for these features for users in your organization, determining, for example, how frequently to run AutoArchive and whether to prompt users before running AutoArchive.
If you configure Exchange Server document management settings for users as well as Outlook retention and AutoArchive settings, be aware that the Exchange settings can affect Outlook retention and AutoArchive behavior. See the Working with Outlook archiving and Exchange document management section later in this article.

How AutoArchive works in Outlook
Outlook mailboxes grow as users create and receive items. To keep mailboxes manageable, users need another place to store — or archive — older items that are important but not frequently used. It is typically most convenient to automatically move these older items to the archive folder and to discard items whose content has expired and is no longer valid. AutoArchive manages this process automatically for users.
Scheduling automatic archiving
AutoArchive is on by default and runs automatically at scheduled intervals, removing older and expired items from folders. Older items are those that reach the archiving age a user specifies (the default archiving age varies by the type of Outlook item). Expired items are mail and meeting items whose content is no longer valid after a certain date, such as a mail item set to expire two months ago that still appears in a user's Inbox.
Users can specify an expiration date on items in Outlook at the time they create or send the item or at a later date. When the item expires, it is unavailable and shows in a folder list with a strike-out mark through it.
Archive folder location
When AutoArchive runs, it can delete items or move items to an archive folder, depending on the settings you specify.
The archive file is an Outlook data file (PST file) that appears as Archive Folders in the Outlook folder list. The first time AutoArchive runs, Outlook creates the archive file automatically in the following location:
%UserProfile%\Local Settings\Application Data\Microsoft\Outlook\Archive.pst
How retention settings work in Outlook
In addition to the AutoArchive settings, you can also enable retention policy settings for items in user mailboxes. Retention policy settings can help users to follow retention policy guidelines that your company establishes for document retention.
| Note:
|
|---|
|
Because retention policies settings are part of Outlook's AutoArchive functionality, retention settings only run when AutoArchive is run. Running an archive manually does not trigger retention settings enforcement. |
Retention Group Policy settings in Outlook can be configured to follow company policies, to encourage users to retain documents and items for only a fixed period of time. Retention settings implementation requires AutoArchive to be enabled, but retention settings take precedence over AutoArchive settings.
Working with Outlook archiving and Exchange document management
If Microsoft Exchange is configured to implement document management features that set e-mail message expiration dates for user mailboxes, make sure that Outlook archiving settings are configured so that item expiration and archiving or deletion work predictably for users.
By default, in most configurations, Exchange retention policies override Outlook retention settings. Users who are not aware that Exchange policies take precedence might lose Outlook items. This can happen if users expect their AutoArchive settings to move items to an Outlook data file and instead the items are removed by Exchange document management procedures.
To help prevent user confusion this scenario, disable the option to configure manual archiving. Use the following procedure to disable manual archiving by using Group Policy.
Disable manual archiving by using Group Policy
-
In Group Policy, load the Office Outlook 2007 template (Outlk12.adm).
-
Under User Configuration\Administrative Templates\Microsoft Office Outlook 2007\Tools | Options\Other\AutoArchive, double-click Disable File|Archive.
-
Click Enabled.
-
Click OK.
