Managing Exchange Server Mailboxes

Management Tools for Administering Exchange Server

The Active Directory Users and Computers Management Console

The Active Directory Users and Computers snap-in is extended to support the management of mailbox configurations and settings. The Active Directory Users and Computers management console is the central tool used for creating and managing user account and computer account objects and configuration settings in Windows domains.

Users can apply different permissions to different Exchange server objects. Permissions can be assigned at the Exchange organization level and at the Administrative Group level:

• Exchange Full Administrator
• Exchange Administrator
• Exchange View Only Administrator

The Exchange System Manager

The Exchange System Manager uses extension snap-ins to perform its tasks. Extension snap-ins extend other extensions’ functionality. To maintain configuration information, Exchange System Manager communicates with a Windows 2000 or Windows Server domain controller.

The Exchange System Manager window is displayed when Exchange System Manager is started. It contains directory information relating to the Exchange organization from the specified domain controller. Multiple Exchange System Manager windows can be simultaneously displayed. To do this, simply select the particular node and select New Window From Here to open a new Exchange System Manager window.

The Mailbox Manager utility

The Mailbox Manager utility is automatically installed when an Exchange Server server is installed. The Mailbox Manager utility allows users to configure mailbox recipient policies to manage email retention policies and mailbox cleanup tasks. With Exchange Server, users do not need to configure mailbox management on each specific Exchange server. Policies can be replicated through Recipient Update Service (RUS).

Mailbox recipient policies can be configured to:

• Delete mailbox items based on the following:
  • Size
  • Time
  • Age limit
  • Specific folders
• Move mailbox items based on the above criteria.

A few preconfigured options that can be specified when configuring mailbox recipient policies are listed here:

• Move to Deleted Items option: This option moves items to the Deleted Items folder in the Exchange mailbox. Items that match certain predefined criteria are included in the move to the Deleted Items folder.
• Move to System Cleanup option: This option creates a partial replica of the mailbox folders and any items that surpass the predefined criteria are moved to the system folders and are then stored there.
• Delete Immediately option: The Delete Immediately option deletes each item that surpasses the predefined policy criteria.
• Generate Report Only option: Determines the impact of initiating a policy to move items or to delete items. The options users can choose between when using the Generate Report Only option are listed here:
  • Send Summary Report to Administrator – provides information on the size of all items that are deleted or moved to other folders.
  • Send Detailed Report to Administrator – provides information on all items processed and all affected policies and folders.

The Exchange System Manager creates mailbox recipient policies in the Recipient Policies container. When users configure mailbox cleanup tasks, they have to define the message size limits and message age limits.

The default values for message size limits and message age limits are listed here:

• Message size limits: 1024 KB
• Message age limits: 30 days

The Mailbox Recovery Center Tool

The Mailbox Recovery Center tool is a new Exchange Server feature that can be initiated from within the Exchange System Manager.

The uses and features of the Mailbox Recovery Center tool are summarized here:

• Recover and reconnect disconnected mailboxes to Active Directory accounts.
• Mailbox conflicts between Active Directory accounts can be identified and resolved.
• Mailboxes can be merged as well.
• Individual mailboxes and multiple mailboxes can be recovered at one time.

Through the Event Viewer, various system events and errors can be viewed and examined. All events are written to Event logs. Exchange services mainly use the application event log.

Services snap-in can be used to manage services, including the Exchange Server services, running on the server. The snap-in is utilized to configure settings including the Startup Type and the Log On account for Exchange Server services to run. There are a number of recovery options with different escalation levels, such as Take No Action, Run A File, Reboot The Server, or Restart The Service that can be configured.

A better option than utilizing the Services snap-in is using the Computer Management utility . The Computer Management utility manages applications and services on the local computer and on a remote server. The utility also enables access to systems tools and storage utilities: Event Viewer, System Information, Removable Storage, and Disk Management.

When it comes to monitoring the system’s state, the Computer Management snap-in or Performance utility can be utilized. The Performance Logs and Alerts tool can be accessed through the Computer Management snap-in and Performance utility. However, only the Performance utility offers System Monitor use. When utilizing System Monitor to monitor performance, performance data can be specified in charts, reports, and real-time graphs. Both the performance of local computers and remote computers can be monitored.

Programs and processes running on a Windows computer can be controlled, monitored, and started or stopped through the Task Manager. Task Manager includes a Processes and Performance tab that contain valuable information on the active processes running on a server, resource utilization, and CPU and memory usage. The End Process button located in the Processes tab and End Task button found in Applications tab can be used to end running process.

The Backup utility is included in each Windows version and is typically used for backing up system files and network data. The backup utility makes it possible for backup jobs to be scheduled. Through the Backup utility, backups can be scheduled to run during off peak hours.

The Windows Registry Editors can be used to examine and change startup settings of Exchange Server 20003 services. The following can modify these service settings:

• REGEDIT.EXE
• REGEDT32.EXE

Any modifications made are written to the Registry immediately and there are controls that prevent invalid parameters from being specified. It is recommended to only use the Registry Editor when no other administrative tool is available for use.

Similar to the Registry Editors, the Active Directory Service Interface (ADSI) Edit snap-in allows Active Directory information to be directly changed and deleted from the Domain, Configuration, and Schema partitions.
