Exchange 2010 SP2 RTM

Did you all know that Exchange Server 2010 Service Pack 2 (SP2) has been released last night, raising the Exchange version number to You can download Exchange 2010 SP2 here.

For those still unaware, the 530Mb+ file (1,3 GB extracted) contains the full set of binaries; you can use it to upgrade existing RTM or SP1 installations or deploy new Exchange 2010 SP2 installations.

Besides the usual set of hotfixes, SP2 introduces the following features:

Address Book Policies
Address Book Policies, also known as GAL segmentation, ABPs are meant to segmented the address book, giving users a certain view of the address book like Address List Segregation did for Exchange 2003/2007. ABPs were already announced back in January. I wonder how this affects for instance MailTips, as MailTips might report on organization-wide figures (sending mail to X users) while the end user may only see a small fragment of the population. Also, be advised that clients bypassing the CAS server for directory lookups, e.g. LDAP queries, don’t benefit from ABPs. Think Outlook for Mac but also multifunctionals, fax solutions etc.

OWA mini
This will be a lightweight browser like OMA in the past, meant for simple browsers.

Hybrid Configuration
This wizard is to make the configuration of an on-premise Exchange and Office 365/Exchange Online more simple, reducing the steps required from 49 to 6.

OWA Cross-Site redirection
This will allow clients to be silently redirected to the proper site if they log on to a CAS server located in a site different than the site where their mailbox is hosted and externalURL has been specified there. This greatly increases the single sign-on experience.

The releases notes are not available at this time.
