So long Exchange features--we hardly knew ye!

Here are some of the features that Microsoft is taking away in Exchange 2007; ones that could make migrating from Exchange 2003 to Exchange 2007 a little more difficult.

You've probably read a lot of articles talking about what Exchange 2007 brings to the table. But, what about the stuff that Microsoft is taking away? I won't be able to go into an exhaustive list of everything Microsoft has removed from Exchange 2007, but will provide you with some of the big ones that could make migrating from Exchange 2003 to Exchange 2007 a little more difficult.

  • Exchange 5.5 integration: Unlike Exchange 2000 and 2003, Exchange 2007 cannot coexist with Exchange 5.5. If you have existing Exchange 5.5 servers in your organization, you must move the mailboxes to Exchange 2000 or Exchange 2003 before you can install Exchange 2007.
  • Network-attached storage: Exchange 2007 does not support network-attached storage. Exchange 2007 supports only iSCSI.
  • Active Directory Computers and Users-based management: Personally, I hate this one since it will make user management more difficult. Microsoft has removed the Exchange extensions from Active Directory Users and Computers. To manage anything mail-related, you must use the GUI-based Exchange Management Console or the command line-based Exchange Management Shell.
  • ExMerge: Gone. Microsoft has replaced ExMerge with the command line tool Export-Mailbox and the GUI-based Move Mailbox Wizard.
  • Public folder GUI-based management: Microsoft eventually plans to completely eliminate public folders in Exchange and has made great efforts in Exchange 2007 to decouple those previously depended on public folders. For example, free/busy information, while still using Public Folders for legacy clients, is no longer necessary once all of your clients are at Outlook 2007. As the first step in a bid to eliminate public folders in favor of a SharePoint-based repository, Microsoft has removed the GUI-based management functionality from the new Exchange Management Console. Microsoft recommends that, if you need this functionality, you keep one Exchange 2000 or Exchange 2003 server in your organization.
  • NNTP: Gone. NNTP has been removed from Exchange 2007.
  • Active/Active clustering: Only active/passive clustering is supported in Exchange 2007.
  • This isn't a complete list of what Microsoft has gutted from Exchange 2007. While some of these features won't be missed, some will take some getting used to and will require workarounds.
