Exchange 2010 Service Pack 2 - What's New

Exchange Server 2010 has released SP2, It is not such a major update as SP1, but there are small numbers of new features that have been added to the product. There are around five hundred Exchange Server 2010 SP1 Update Rollup fixes that have been included in to SP2. But there is a lot of great stuff inside SP2 that should appeal to you.


Hybrid Configuration Wizard

Exchange Server 2010 introduces the Hybrid Configuration Wizard, which provide you an Exchange 2010 on-premises environment can be integrated with Office 365. This is called rich coexistence. It provides the seamless look and feel of a single Exchange organization and offer administrator the ability to extend the feature-rich experience and administrative control of an on-premises organization to the cloud.

Using the Hybrid Configuration Wizard you can:

1. Share free/busy information between on-premises Exchange 2010 organization and Office 356.

2. Move mailboxes between on premises Exchange 2010 and Office 365, preserving the outlook profile and the OST file.

3. You can use Message tracking between on-premises HUB transport server and Office 365 for mail flow and troubleshooting.

4. You can use Mail tips for mailboxes located both in Office 365 and in the on-premises Exchange 2010 environment.

5. Use online Archiving where online archiving is located in Office 365.

6. Use OWA redirection between Office 365 and the on-premises Exchange 2010 implementation.

To setup a ‘rich coexistence scenario’ with Office 365 a number of server need to be installed:

• A Directory Synchronization Server {DirSync} that sync the local AD with the Office 365 directory. This way one address List is created where mailboxes can exist both on-premises and the O365.

• An Active Directory Federation Services 2.0 {ADFS} server that can provide the true single sign-on solution. Using ADFS it is possible to logon to the local AD domain and at the same time logon to the O365 mailbox using the local credentials.

• The Exchange 2010 server itself that is used together with O365.



Mini OWA

In Exchange 2003 a special version of the webmail was available for WAP enabled mobile device. Using a WAP-enabled mobile device was possible for users to access their mailbox using a character-based interface. This was called OMA but this feature was removed from Exchange 2007. It has now turned as OWA mini in Exchange 2010 SP2. The mini OWA provides users with the following basic functionality:

• Access to e-mail, calendar, contact, tasks and 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.

Address Book Policies

In Exchange 2007 and earlier it was possible to implement a feature called Address List Segregation. This feature made it possible to use several fully-separated address lists in Exchange by using the Access Control List (ACLs) on the various address lists to achieve this. ACLs are the means by which permission are assigned in a Windows OS. But Exchange 2010 introduces a new technology called the Address Book Service that is running on the Exchange 2010 CAS server. Therefore the ACL based method didn’t work anymore on the Exchange 2010.

Exchange 2010 SP@ introduces the address book policy object which can be assigned to a mailbox user. The ABP determines the global address list, offline address book, room list and address lists that are visible to the mailbox uses that is assigned the policy. Address book policies provide a simpler mechanism to accomplish GAL separation for the on-premises organization that needs to run disparate GALs.

Cross-Site Redirection

In large, Geographical dispersed companies it is likely that several location are used, each hosting their own Exchange 2010 servers {same AD and Exchange Org} and their own Internet connection. With Exchange 2010 SP2, you can enable a silent redirection when a CAS receives a client request that is better serviced by a CAS located in another AD site. This silent redirection can also provide a single sign-on experience when form-based authentication is enabled on each CAS. The only bad thing is that this only work when the CAS is connected directly to the Internet, without a reverse proxy solution.


Multi-Valued Custom Attributes

Exchange 2010 SP2 introduces five new multi-value custom attributes that you can use to store additional information for mail recipient objects. The ExtensionCustomAttribute1 to ExtensionCustomAttribute5 parameters can each hold up to 1,300 values; you can specify multiple values as a command line. The following cmdlets support these new parameters;

• Set-DistributionGroup

• Set-DynamicDistributionGroup

• Set-Mailbox

• Set-MailContact

• Set-MailPublicFolder

• Set-RemoteMailbox


Litigation Hold

In Exchange 2010, you can’t disable o remove a mailbox that has been placed on litigation hold. To bypass this restriction, you must either remove litigation hold from the mailbox, or us the new IgnoreLegalHold switch parameter when removing or disabling the mailbox.
