This topic lists the new functionality available for Mailbox server, mailboxes, and recipients in Exchange Server 2010.
For information about the other mailbox features, see the following topics:

What would you like to do?

Calendaring
Users can share information such as calendar and contacts folders, or access free busy data with users who reside in a different organization. For more information, on free busy access to different organizations, see Managing Federated Sharing.
Note: |
|---|
|
Contacts sharing will first be available for e-mail users who are using Outlook 2010. For information about when Outlook 2010 will be available, visit the Microsoft Office Online Web site.
|
Before you can share any information between organizations, a Federated 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
The 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 that occur for single and recurring meeting items for mailboxes that are homed on that mailbox server so that recipients will not miss meetings or have unreliable meeting information.
For more information about the Calendar Repair Assistant, see Understanding Calendar Repair.

Resource Scheduling

Moving Mailboxes
You can now 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 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 will begin the process to move a mailbox. You can test the readiness of a mailbox by running the command with the WhatIf parameter.
-
Get-MoveRequest This cmdlet will retrieve statistics regarding the status of an on-going mailbox move that was initiated using the New-MoveRequest command.
-
Remove-MoveRequest This cmdlet will cancel an on-going mailbox move that was initiated using the New-MoveRequest command.
-
For more information about how to use the new cmdlets, see:

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 or time-wasting e-mail blasts from being delivered to large audiences. For more information, see Understanding Moderated Transport.

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 Outlook Web App and Outlook 2010 and new UI has been added to allow administrators to manage the distribution group ownership and how users can be added to the distribution group.
To see the new UI, open a distribution group's property dialog box (right-click on the group) and the there are new changes on the Group Information tab and the Membership Approval tab.
The ManagedBy parameter has been updated to indicate ownership of a distribution group and users specified in the ManagedBy parameter can modify the distribution group settings.
Note: |
|---|
|
The functionality for the ManagedBy parameter in the dynamic distribution groups cmdlets did not change.
|
The following cmdlet changes have been made to support this feature:

Mailbox Folder Permission Management
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
In Exchange 2007 SP1, you could perform bulk recipient management to move, remove, and disable or enable mailboxes in the EMC. In Exchange 2010, bulk recipient management has been expanded to allow you to include the following tasks:
-
Properties Select multiple recipients in the result pane and then click Properties in the action pane. Properties that you can't bulk edit are grayed-out.
Note: |
|---|
|
You can only bulk edit recipient properties when the same recipient types are selected.
|
-
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.

Send Mail
You can send mail to recipients from the EMC. Select the recipient in the result pane, and then click Send Mail in the action pane. You must configure an e-mail account setup 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 cannot send mail to resource mailboxes.

Personal Archive
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. In this way, the user has direct access to e-mail within the archive just as they would their primary mailbox. Users can “drag and drop” e-mail from .PST files into the personal archive for easier online access. E-mail items from the primary mailbox can also be offloaded to the personal archive automatically using retention polices, which reduces the mailbox size and improves application and network performance. In addition, users can search both their personal archive and primary mailbox using Outlook 2010 or Outlook Web App.
