SUMMARY
You can use system policies to apply consistent settings to multiple servers, mailbox stores, and public folder stores at one time. This step-by-step article describes how to use mailbox store policies to manage the following items:
 * Storage space
 * Indexing
 * Databases
 * Associated default public folder stores
 * Mail archive settings
 * Offline address lists

This article also describes how to apply these policies selectively to one or more mailbox stores throughout your Exchange 2000 organization.

Requirements
The following list outlines the recommended hardware, software, network infrastructure, and service packs that you need:


 * Windows 2000 Server with Service Pack 2 (SP2)
 * Active Directory
 * Microsoft Exchange Server 2000 with Service Pack 1 (SP1)

This article assumes that you are familiar with the following topics:
 * The Exchange 2000 Administrator console
 * The role of administrative groups in Exchange 2000

A Description of the System Policy Functionality
Before you implement Mailbox system policies, you must understand the areas that policies can configure, which include:
 * General settings such as default public store, offline address list, message archival, Secure/Multipurpose Internet Mail Extensions (S/MIME) signatures and message display settings.
 * Database settings such as maintenance intervals.
 * Storage limits such as mailbox sizes, maintenance scheduling, and deleted item retention settings.
 * Timings for running incremental and full populations of full-text indexes.

You can use system policies to configure most of the settings that you see on the General tab, the Database tab, the Limits tab, and the Full-Text Indexing tab in all of the mailbox stores' properties.

If you configure a system policy for mailbox management, you can apply that policy to any mailbox store in any storage group on any server in the administrative group. If you use system policies, you can apply one group of settings to multiple mailbox stores.

Alternatively, you can have several different system policies, and then select the policy that you want to apply to each mailbox store.

How to Create a System Policies Container

 * 1) Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
 * 2) Right-click the   (Exchange) icon at the top of the tree (where   is the name that you selected for your Exchange 2000 organization), and then click Properties.
 * 3) Click Display administrative groups.

Optionally, you can also click Display routing groups; however, this setting not required to set administrative permissions.
 * 1) Click OK.
 * 2) Restart Exchange System Manager, and then confirm that a new object named &quot;Administrative Groups&quot; is displayed in the left pane.
 * 3) Double-click Administrative Groups, and then double-click the administrative group to which you want to add the policy.
 * 4) If you do not already have a System Policies folder, right-click the respective administrative group, point to New, and then click System Policy Container.

How to Create a Mailbox Store Policy
 Right-click the newly created System Policies folder under the administrative group, point to New, and then click Mailbox store policy. Select the check boxes for the elements that you want this policy to configure.

The example in this article assumes that you select all of the following check boxes:  General Database Limits Full-Text Indexing</li></ul>

</li> On the General tab, type the name for the new system policy.

Microsoft recommends that you use a name that describes the policy, for example, &quot;System Policy for Power Users.&quot;</li> Click the General (Policy) tab, and then configure a default public store for all of the mailbox stores that are associated with this policy.

If you define more than one public folder store, you can change this association. However, because Outlook client computers can view only the first public folder tree that is linked to the default public folder store, it is not necessary for you to change the association.</li> If you have configured alternative Offline address lists, associate these address lists with your mailbox stores.

It is not necessary to associate these address lists with your mailbox stores, unless you are running either a hosted environment or virtual organizations within Exchange 2000.</li> To archive messages sent or received by mailboxes on this store, click Archive all messages sent or received by mailboxes on this store.

The archive setting is useful for auditing; however, you may need to specify in your users' organizational terms and conditions that you are archiving messages.</li> Click Browse, click the user or the folder that you want to archive, and then click OK.</li> If all of your clients that connect to all mailbox stores support S/MIME digital signing, click Clients support S/MIME signatures.</li> Click Display plain text messages in a fixed-sized font.

Use this setting if your users report that messages from external domains are not displayed properly.</li> Click the Database (Policy) tab, click a time when you want online maintenance to run or click Customize.

If you select a maintenance interval for the mailbox stores that are governed by this policy, this time determines when online compaction runs.</li> If you click Customize, either click a day in the left column, and then click a time on the top row or click and hold the mouse button as you sweep across the time slots to configure the update interval.

NOTE: To configure the schedule to be displayed in hour slots or in 15-minute slots, click the appropriate option under Detail View.</li> Click OK.</li> Click the Limits(Policy) tab, and then select one or all of the following check boxes under Storage limits: <ul> Issue warning at: Select this check box to warn the user that their mailbox has exceeded its limit. However, normal functioning of the mailbox continues.</li> Prohibit send at: Select this check box to send a warning message that states that the user will not be able to send any more messages until they delete or archive their old mail. However, users can still receive messages.

NOTE: Type a value (in kilobytes [KB]) for the size of the mailbox, for example, 100,000 KB for normal users or 200,000 KB for the power users.</li> Prohibit send and receive at: Select this check box to send a warning message that states that the user has exceeded mailbox limits. If the user receives this message, the user cannot receive any messages.

NOTE: Type a value (in kilobytes [KB]) for the size of the mailbox, for example, 100,000 KB for normal users or 200,000 KB for the power users.</li></ul> </li> Either click the time that you want the warning messages to be generated in the Warning message interval box or click Customize.</li> If you click Customize, either click a day in the left column, and then click a time on the top row or click and hold the mouse button as you sweep across the time slots to configure warning settings.

NOTE: To configure the schedule to be displayed in hour slots or in 15-minute slots, click the appropriate option under Detail View.</li> <li>After you configure the warning message interval times, click OK.</li> <li>Set deletion item retention times for messages and for deleted mailboxes under Deletion settings.

Microsoft recommends that you set the deletion setting to 7 days for messages and 30 days for mailboxes.</li> <li>If you want maximum control of your database sizes, configure the Keep deleted items for (days) setting to 0. Otherwise, Microsoft recommends that you a configure this setting to 7 days.</li> <li>Click the Full-Text Indexing(Policy) tab, and then either click a time that you want to run an incremental update of the full-text index in the Update Interval box or click Customize.</li> <li>If you click Customize, either click a day in the left column, and then click a time on the top row or click and hold the mouse button as you sweep across the time slots to configure warning settings.

NOTE: To configure the schedule to be displayed in hour slots or in 15-minute slots, click the appropriate option under Detail View.</li> <li>Configure the Rebuild interval setting.

If you perform a rebuild operation, the search catalog is completely indexed. Microsoft recommends that you perform a rebuild operation once a week at midnight on Saturday or Sunday.</li> <li>Click OK.</li></ol>

How to Apply a Mailbox Policy to a Mailbox Store
To apply the mailbox policy that you just created to one or more mailbox stores:
 * 1) Right-click the system policy that you just created, and then click Add Mailbox Store.
 * 2) Double-click each mailbox store that you want this policy to control, and then click OK.
 * 3) When you receive a message that prompts you to confirm that you want to add the items to the policy, click Yes.

The mailbox stores are now displayed in the right pane of Exchange System Manager if you click System Policies. Click the policy that you created.

How to Confirm That You Configured the System Policies Correctly
To confirm that the system policy has been assigned:
 * 1) Open the properties of one of the mailbox stores to which you applied the policy. All the settings that can be configured by using the policy are shaded.
 * 2) Open the properties of a mailbox store on which you applied the system policy, and then click the Policies tab. A list of all of the policies that apply to that particular mailbox store are displayed.
 * 3) Click the System Policies object in Exchange System Manager. A list of policies and the time that these policies were last applied is displayed.

Troubleshooting
To prevent policy conflicts, you can only associate a mailbox store that has more than one policy if the two policies do not configure the same mailbox store's properties.
