Well at least for Technet and MSDN subscribers.
Exchange 2010 was built from the ground up with the “cloud” in mind and is the mail engine behind Microsoft’s online email offering(s) (part of BPOS). I did not want to do another “what is new in Exchange 2010” so I though it would be good to highlight what is missing, changed or discontinued when compared to Exchange 2007.
Architecture changes
Storage Groups GONE! that’s right it’s all about the database now and these are at the organisational level, so no more shared log files between storage groups.
ESE Streaming backup APIs GONE! Backup’s are now VSS based so you can now even use Windows Server Backup to protect your valuables.
Outlook Web Access (App)
Document access GONE! well in this release anyway. So no SharePoint libraries or file shares can be access via OWA :-(
Web Parts GONE! Not supported in this release.
OWA themes GONE! Not supported in this release.
Reading pane GONE! well not fully true, it can on longer be placed at the bottom of the window.
New posts can not longer be created in the mailbox, this can only be done in Public Folders.
HA Features
CCR, LCR, SCR GONE, GONE and GONE! but only to be replaced by “High Availability and Site Resilience” features which includes Database Availability Groups, Mailbox Databases Copies and Active Manager the replacement for Cluster service in previous releases.
Setup /recoverCMS is replaced with Setup /m:recoverServer
Clustered mailbox servers are also replaced with “High Availability and Site Resilience”
