You can't manage Exchange 2010 objects using the Exchange Server 2003 System Manager. You can use the EMC in Exchange 2010 to view certain properties and objects, like the routing group connector in Exchange Server 2003. You can't perform message tracking configuration tasks between Exchange 2010 and Exchange 2003. You must use Exchange 2003 messaging tracking tools within your Exchange 2003 organization, and Exchange 2010 messaging tracking tools within your Exchange 2010.

The Exchange Management Console (EMC) is available in both Exchange Server 2010 and Exchange Server 2007. The following lists the tasks and actions that can be performed using the EMC in either Exchange 2010 or Exchange 2007:

• Actions that create objects, such as new mailboxes or a new offline address book (OAB), can only be performed on a version of the EMC that's the same as the target object. For example, creating a mailbox on an Exchange 2007 Mailbox server must be performed with the EMC in Exchange 2007. The following applies:
  
  
  • Exchange 2007 Mailbox databases can't be managed from the EMC in Exchange 2010, although these databases can be viewed.
    
    
  • The EMC in Exchange 2010 can't enable or disable Exchange 2007 Unified Messaging mailboxes.
    
    
  • The EMC in Exchange 2010 can't manage Exchange 2007 mobile devices.
    
    
• Actions that require viewing of objects can be performed from any version of the EMC to any version of Exchange objects, with a few exceptions:
  
  
  • Exchange 2010 and Exchange 2007 transport rule objects can only be viewed from their corresponding version of the EMC.
    
    
  • Exchange 2010 and Exchange 2007 servers can only be viewed from their corresponding version of the EMC.
    
    
  • The Queue Viewer tool in the EMC in Exchange 2010 can't connect to an Exchange 2007 server to view queues or messages.
    
    

    Note:
    If an Exchange 2007 object (such as a storage group) is no longer present in Exchange 2010, there's no interoperability expected or provided because Exchange 2010 isn't aware of the feature.

• You can't use message tracking configuration tasks between Exchange 2010 and Exchange 2007. You must use Exchange 2007 messaging tracking tools within your Exchange 2007 servers, and Exchange 2010 messaging tracking tools within your Exchange 2010 servers.
  
  

The following is a list of Exchange 2010-only and Exchange 2007-only objects. These objects are available for viewing, managing, and creating only in the corresponding version of the EMC.

Note:
Be aware that managing an object in the Exchange 2010 Exchange Control Panel can upgrade the object. As a result, it can't be managed by the Exchange 2007 management tools (EMC, Shell) that created the object.

Exchange 2007 objects no longer present in Exchange 2010:

• Storage groups
  
  
• Exchange Administrators
  
  
• WebDAV
  
  

Exchange 2010 Management Console-only objects:

• Database availability group
  
  
• Certificate creation
  
  
• Database copies
  
  
• Federation trust
  
  
• Sharing relationships
  
  
• Sharing policies
  
  
• Microsoft Office Outlook Web App mailbox policies
  
  
• Customer Experience Program properties
  
  

Side-by-Side Management Console

To use the side-by-side EMC feature, the Exchange 2007 EMC must first be installed on a non-Exchange administrative machine. After the Exchange 2007 EMC is installed, you can then install the Exchange 2010 EMC to run in a side-by-side scenario.

Note:

Exchange 2010 EMC can only be administered from a 64-bit machine. Therefore, for side-by-side management, the Exchange 2007 EMC must be installed on a 64-bit machine. Side-by-side management for Exchange Server 2003 and Exchange 2010 management tools isn't supported, because Exchange Server 2003 management tools can only be run on 32-bit machines. However, you can use 32-bit Windows PowerShell 2.0 and remotely access your Exchange 2010 environment.
