Mailbox Store Controlled by Policy

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft® Exchange Best Practices Analyzer Tool queries the Active Directory® directory service to determine the value of the msExchPolicyList attribute of each mailbox store object. The msExchPolicyList attribute determines whether an Exchange Server mailbox policy has been created and assigned to a mailbox store. If the Exchange Server Analyzer finds that the msExchPolicyList attribute has been set, the Exchange Server Analyzer displays a non-default configuration message.

By default, when mailbox stores are created, they do not have a mailbox policy assigned. Usually, administrators create mailbox policies and then assign them to multiple mailbox stores. These policies apply administrative settings such as storage limits, indexing updates, maintenance intervals, mappings to public stores, and offline address lists. If a mailbox policy has been created and assigned to a mailbox store, the Analyzer tool displays a message stating that the mailbox store is currently controlled by a mailbox policy. No additional actions are required.

To remove a mailbox policy from a mailbox store
  1. Open Exchange System Manager, and then expand Administrative Groups in the console tree.

  2. Expand First Administrative Group, and then select System Policies.

  3. In the results pane, right-click the mailbox store, and then click Remove from policy.

  4. In the Exchange System Manager window, click Yes to confirm the removal of the mailbox store.

If the System Policies node is not visible in the console tree in Exchange System Manager, configure Exchange System Manager to display Administrative Groups.
