Microsoft has officially released SP1 for Exchange Server 2010. The update had previously been available via test betas and to select journalists, but it’s finally available to the general public. We’ve gone over the specifics before, but here’s a refresher. It includes:

• Improvements to the Personal Archive feature, including the ability to provision the archive on a separate database and use tiered storage; look for a feature article about implementing Personal Archives in Windows IT Pro in the near future.
• Improvements to Outlook Web App (OWA; formerly Outlook Web Access), including easier navigation and the ability for users to apply themes; you can read more about OWA improvements in Tony Redmond’s article “Exchange 2010 SP1: More Than a Simple Upgrade.”
• Easier management of Role Based Access Control (RBAC) in Exchange Control Panel (ECP).
• Easier management for retention policies and tags added through Exchange Management Console (EMS).
