We've published a post on the Exchange Team Blog that provides the first public details about Exchange Server 2010 Service Pack 1 (SP1).  SP1 will of course include fixes and enhancements in the areas customers have helped us identify (including code from all of the Exchange 2010 post RTM update rollups we've released to date).  But SP1 will also include some new features and functionality changes, as well. For example, we've made several improvements to the Multi-Mailbox Search features:

  • A new search preview helps with early case assessment by providing you an estimate on the number of items in the result set-with keyword statistics-before e-mail located in the search are copied to the designated discovery mailbox.
  • And, a new search result de-duplication option, when checked, only copies one instance of a message to the discovery mailbox.

We've also made improvements to the Exchange Management Console (EMC) and the Exchange Control Panel (ECP). For example, one of my favorite changes is in there - new GUI property fields for database availability group (DAG) IP addresses and alternate witness server and alternate witness directory settings:

Edit DAG IP Addresses  Alternate Witness Server and Directory

There are other cool GUI enhancements, too:

  • Create/configure Retention Tags + Retention Policies in EMC
  • Recursive public folder settings management (including permissions) in EMC 
  • Configure Transport Rules in ECP
  • Configure Journal Rules in ECP
  • Configure MailTips in ECP
  • Provision and configure the Personal Archive in ECP
  • Configure Litigation Hold in ECP & EMC
  • Configure Allow/Block/Quarantine mobile device policies in ECP
  • RBAC role management in ECP

Finally, there are two big changes with respect to the archive mailbox.  Both are such huge changes, that I don't want to spoil the surprise.  So, head over to the Exchange team blog, and check out the post Yes Virginia, there is an Exchange Server 2010 SP1.
