Exchange 2010 SP2

Exchange Server 2010 Service Pack 2 (SP2) has been released, raising the Exchange version number to 14.2.247.5.

For those still unaware, the 530Mb+ file (1,4 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 segmentize the address book, giving users a certain view of the address book like Address List Segregation did for Exchange 2003/2007. An Address Book Policy is a combination of global address list, offline address book, room list and address lists and can be assigned to mailbox users. For more information, see Understanding Address Book Policies.
  • OWA mini
    This will be a lightweight browser like OMA in the past, meant for simple browsers. It offers simple features, like:

    • Access to e-mail, calendar, contacts, tasks and the global address list.
    • Access to e-mail subfolders.
    • Compose, reply to, and forward e-mail messages.
    • Create and edit calendar, contact, and task items.
    • Handle meeting requests.
    • Set the time zone and automatic reply messages.

    For more information, see Understanding the Mini Version of Outlook Web App.

  • Hybrid Configuration Wizard
    This wizard is to streamline the process of configuring a hybrid deployment between on-premises and Office 365 Exchange organizations, reducing the steps required from 49 to 6. For more information, see Understanding the Hybrid Configuration Wizard.
  • OWA Cross-Site Redirection
    This 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, improving the single sign-on experience for those users. For more information, see Understanding Proxying and Redirection.
  • Mailbox Auto-Mapping
    The automatic mapping of mailboxes where end users have Full Access permissions in Outlook 2007 or Outlook 2010, can be turned off using the Automapping parameter in conjunction with the Add-MailboxPermission cmdlet. Unfortunately, there’s no option to set this via the GUI when using the Exchange Management Console to grant Full Access permissions. For more information, see Disable Outlook Auto-Mapping with Full Access Mailboxes.
  • Mailbox Replication Service
    The Mailbox Replication Service (MSProxy), used for moving mailboxes cross-forest (including cross-premise), can now be easily configured using cmdlet parameters instead of through editing a web.config file on each Client Access server. The related cmdlets are New-WebServicesVirtualDirectory and Set-WebServicesVirtualDirectory, the parameters are MRSProxyEnabled and MaxMRSProxyConnections. For more information, see Start the MRSProxy Service on a Remote Client Access Server.
  • Multi-Valued Custom Attributes
    SP2 introduces five new multi-value custom attributes, ExtensionCustomAttribute1 to ExtensionCustomAttribute5, for storing additional information for mail recipient objects.
  • Disabling or Removing Mailboxes on Litigation Hold
    In SP2, you can’t disable or remove a mailbox that has been placed on litigation hold, unless you explicitly specify the new IgnoreLegalHold switch.

After preparing your forest for Exchange 2010 SP2, the schema version number will have changed. Check the Schema Versions page for information on the new ObjectVersion and RangeUpper values for Exchange 2010 SP2.

Note that SP2 introduces an additional requirement, which is the IIS 6 WMI Compatibility feature; you can add this feature using the GUI or by using the Powershell cmdlets Import-Module ServerManager followed by Add-WindowsFeature Web-WMI.

The proper method to upgrade mailbox servers that are a member of a Database Availability Group is described here.
