Exchange 2010 Service Pack 2

source : http://blogs.technet.com/b/exchange/archive/2011/05/17/announcing-exchange-2010-service-pack-2.aspx

SP2, the following new features and capabilities will be included:

• Outlook Web App (OWA) Mini: A browse-only version of OWA designed for low bandwidth and resolution devices. Based on the existing Exchange 2010 SP1 OWA infrastructure, this feature provides a simple text based interface to navigate the user’s mailbox and access to the global address list from a plurality of mobile devices.
• Cross-Site Silent Redirection for Outlook Web App: With Service Pack 2, you will have the ability to enable silent redirection when CAS must redirect an OWA request to CAS infrastructure located in another Active Directory site. Silent redirection can also provide a single sign-on experience when Forms-Based Authentication is used.
• Hybrid Configuration Wizard: Organizations can choose to deploy a hybrid scenario where some mailboxes are on-premises and some are in Exchange Online with Microsoft Office 365. Hybrid deployments may be needed for migrations taking place over weeks, months or indefinite timeframes. This wizard helps simplify the configuration of Exchange sharing features, like: calendar and free/busy sharing, secure mailflow, mailbox moves, as well as online archive.
• Address Book Policies: Allows organizations to segment their address books into smaller scoped subsets of users providing a more refined user experience than the previous manual configuration approach. We also blogged about this new feature recently in GAL Segmentation, Exchange Server 2010 and Address Book Policies.
• Customer Requested Fixes: All fixes contained within update rollups released prior to Service Pack 2 will also be contained within SP2. Details of our regular Exchange 2010 release rhythm can be found in Exchange 2010 Servicing.

In order to support these newly added features, there will be a requirement for customers to update their Active Directory schema. We’ve heard the feedback loud and clear from our customers on multiple occasions regarding delays that can be caused to deployment as a result of needing to update your schema and as such with the release of Exchange 2010 SP2 are communicating the required changes ahead of release in order to assist our customers with planning their upgrade path ahead of time.

Internet Explorer 9(IE9) and Forefront TMG 2010

After install IE9, Microsoft Forefront Thread Management Gateway management tools cannot work anymore, it gives error message like “member not found”, “refresh failed”.

* Open "C:\Program Files\Microsoft Forefront Threat Management Gateway\UI_HTMLs\TabsHandler\TabsHandler.htc"
* Search for the 3 lines which contain "paddingTop", and remark-out each of them by adding "//" in the begining.
Example: Change the line:
m_aPages [niPage].m_tdMain.style.paddingTop = ((m_nBoostUp < 0) ? -m_nBoostUp : 0) ;
into:
// m_aPages [niPage].m_tdMain.style.paddingTop = ((m_nBoostUp < 0) ? -m_nBoostUp : 0) ;
* Save the file, and re-open TMG management console.
