Earlier last year, we announced that Exchange 2010 Service Pack 3 would be coming in the first half of 2013. Later, we updated the timeframe to Q1 2013. Today, we're pleased to announce the availability of Exchange Server 2010 Service Pack 3, which is ready to download.

Service Pack 3 is a fully slipstreamed version of Exchange 2010. The following new features and capabilities are included within SP3:

  • Coexistence with Exchange 2013:Customers who want to introduce Exchange Server 2013 into their existing Exchange 2010 infrastructure will need the coexistence changes shipping in SP3.

    NOTE: Exchange 2010 SP3 allows Exchange 2010 servers to coexist with Exchange 2013 CU1, which is also scheduled to be released in Q1 2013. Customers can test and validate this update in a representative lab environment prior to rolling out in their production environments as an important coexistence preparatory step before introducing Exchange Server 2013 CU1.

  • Support for Windows Server 2012: With SP3, you can install and deploy Exchange Server 2010 on computers that are running Windows Server 2012.
  • Support for Internet Explorer 10: With SP3, you can use IE10 to connect to Exchange 2010.
  • Customer Requested Fixes: All fixes contained within update rollups released before SP3 will also be contained within SP3. Details of our regular Exchange 2010 release rhythm can be found in Exchange 2010 Servicing.

In addition to the customer reported issues resolved in previous rollups, this service pack also resolves the issues that are described in the following Microsoft Knowledge Base (KB) articles:

Exchange 2010 SP3 FAQ

Here are answers to some frequently asked questions.

  • Q. Does Exchange 2010 SP3 include the fixes in Exchange 2010 SP2 RU6?
    A. Yes. Service Packs are cumulative - they include all fixes included in previous RUs and service packs. Although Exchange 2010 SP2 RU6 was released on the same day as Exchange 2010 SP3, fixes in RU6 are included in SP3.

  • Q. Does Exchange 2010 SP3 include the security fix mentioned in Microsoft Security Bulletin MS13-012?
    Yes, fix for the vulneraiblity in MS13-012 is included in Exchange 2010 SP2 RU6, and (as stated above) fixes from SP2 RU6 are inclued in SP3. We recommend reviewing the related security bulletin before applying an update that contains security fixes.

  • Q. Why release RU6 for SP2 at all if all fixes are included in SP3?
    Exchange 2010 SP2 is a supported service pack (see Exchange Server Support Lifecycle). Customers typically deploy update rollups quickly but take longer to deploy service packs.

  • Q. Is Exchange 2010 SP3 compatible with WMF 3.0/PowerShell 3.0?
    A. Exchange team has validated and supports Exchange 2010 SP3 running on Windows Server 2012, which comes with PS 3.0 by default. Please note that even when running on Windows Server 2012, Exchange 2010 SP3 will still use only PowerShell 2.0 functionality. Exchange team has not validated Exchange 2010 SP3 running on earlier server OSes (2008, 2008 R2) with WMF3 / PS3 installed, and we therefore do not recommend that configuration.

    A. Yes, as mentioned in Exchange 2010 SP3 Release Notes, an Active Directory schema is required.

  • Q. Can I install Exchange 2013 RTM in my Exchange 2010 organization after upgrading to Exchange 2010 SP3?
    A. As mentioned in the post, coexistence of Exchange 2013 in an Exchange 2010 SP3 org requires Exchange 2013 CU1, also scheduled for release in this quarter (Q1 2013).
