This topic lists the new functionality available for Mailbox servers, mailboxes, and recipients in Microsoft Exchange Server 2010.

For information about the other mailbox features, see the following topics:




In Exchange 2010, your users can share information with external users. This information includes calendar, contacts, and free/busy data. For more information about accessing free/busy data from different organizations, see Managing Federated Delegation.

Contact sharing will be available with the release of Microsoft Outlook 2010. For information about when Outlook 2010 will be available, visit Microsoft Office Online.

Before you can share any information between organizations, a federation trust must be established. For more information, see Federation.

The MailboxCalendarSettings commands have been removed. The functionality is replaced by the following cmdlets:

Calendar Repair Assistant

Calendar Repair Assistant (CRA) is a configurable, time-based mailbox assistant that runs within the Microsoft Exchange Mailbox Assistants service on Exchange 2010 Mailbox servers. CRA automatically detects and corrects inconsistencies for single and recurring meeting items in mailboxes. With this functionality, recipients won't miss meetings or have unreliable meeting information.

For more information about CRA, see Understanding Calendar Repair.

Resource Scheduling

You can now use the Exchange Management Console (EMC) to manage resource scheduling by editing the resource mailbox's properties. For more information, see Configure User and Resource Mailbox Properties.

Moving Mailboxes

Exchange 2010 includes cmdlets that allow you to move a mailbox while the end user is still accessing it. These cmdlets are for use in moving Exchange 2010 mailboxes between Exchange 2010 databases. Use the Move-Mailbox cmdlet in Exchange Server 2007 to move legacy Exchange mailboxes.

For more information, see Understanding Move Requests or Managing Move Requests.

Mailbox moves are now managed by the following cmdlets:

  • New-MoveRequest   This cmdlet begins the process to move a mailbox. You can test the readiness of a mailbox by including the WhatIf parameter in the command.

  • Get-MoveRequest   This cmdlet retrieves statistics about the status of an ongoing mailbox move that was initiated by using the New-MoveRequest cmdlet.

  • Remove-MoveRequest   This cmdlet cancels an ongoing mailbox move that was initiated by using the New-MoveRequest cmdlet.

Distribution Groups

Exchange 2010 includes new functionality for both moderated and user-created distribution groups.

Moderated Distribution Groups

You can appoint a moderator to regulate the flow of messages sent to a distribution group. Anyone can send a message to the distribution group alias, but before the message is delivered to all participants, a moderator must review and approve it. This helps prevent inappropriate e-mail messages from being delivered to large audiences. For more information, see Understanding Moderated Transport.

User-Created Distribution Groups

The following is a list of new functionality for user-created distribution groups:

  • New parameters have been added to the distribution group cmdlets to allow users to create and manage their own distribution groups in Microsoft Office Outlook Web App and Outlook 2010.

  • A new user interface (UI) has been added to allow administrators to manage the distribution group ownership, including how users can be added to the group.

    To view the new UI, open a distribution group's property dialog box (right-click the group, and then click Properties). The Group Information and the Membership Approval tabs include the new functionality.

The following table lists the new parameters that support user-created distribution groups.

New parameters added to distribution group cmdlets

New parameter Used in cmdlets
















Also, the ManagedBy parameter has been updated to indicate ownership of a distribution group. Users specified in the ManagedBy parameter can modify the distribution group settings.

The ManagedBy parameter functionality for dynamic distribution groups didn't change.

For more information about distribution groups, see Understanding Recipients and Managing Distribution Groups.

Permission Management for Mailbox Folders

You can manage folder-level permissions for all folders within a user's mailbox. Sharing mailbox folders and calendar folders is managed through a new set of cmdlets. These cmdlets allow you to view, remove, and add permissions for specific users on all designated mailbox folders:

Bulk Recipient Management in the EMC

Exchange 2007 Service Pack 1 (SP1) introduced bulk recipient management for moving, removing, disabling, and enabling mailboxes in the EMC. In Exchange 2010, this functionality is expanded to include the following tasks:

  • Properties   You can select multiple recipients in the result pane, and then click Properties in the action pane. Properties that you can't bulk edit are unavailable.

    You can only bulk edit recipient properties when the same recipient types are selected.
  • Send Mail   You can select multiple recipients in the result pane, and then click Send Mail in the action pane to send an e-mail to multiple recipients. For more information, see the Send Mail section later in this topic.

Personal Archive

A personal archive is a specialized mailbox associated with a user's primary mailbox. It appears alongside the primary mailbox folders in Outlook 2010 or Outlook Web App. Users have direct access to e-mail within the archive just as they would their primary mailbox. Users can drag e-mail from .pst files into the personal archive for easier online access.

Through the use of retention policies, e-mail items from the primary mailbox can be automatically offloaded to the personal archive. This reduces the mailbox size and improves application and network performance. In addition, users can use Outlook 2010 or Outlook Web App to search both their personal archive and primary mailbox.

To learn more, see Understanding Personal Archives.

Send Mail

You can send mail to multiple recipients from the EMC. Select multiple recipients in the result pane, and then click Send Mail in the action pane. You must configure an e-mail account on the computer from which you are sending mail. You can send mail to the following recipient types:

  • User mailboxes

  • Mail contacts

  • Mail users

  • Dynamic distribution groups

  • Distribution groups

You can't send mail to resource mailboxes.
