Exchange Server 2010 SP2 Released

Exchange 2010 SP2 has been released today! Here are the new features/improvements: 

• Hybrid Configuration Wizard
• Address Book Policies
• Cross-Site Silent Redirection for Outlook Web App
• Mini Version of Outlook Web App
• Mailbox Replication Service
• Mailbox Auto-Mapping
• Multi-Valued Custom Attributes
• Litigation Hold

I’m not going to describe what each one of these are/do as the topic What’s New in Exchange 2010 SP2 does the job very well. What I will do is post here some more information once I test them.

Just a quick note: when you try to install it, you might get the following error:

CAS Prerequisites SETUP error: The "IIS WMI Compatibility" component is required.  Install the component via the Web Server Manager.

This is because SP2 introduces a new requirement for CAS servers to have the IIS6 WMI Compatibility role. So, probably the best way is to use one of the following methods:

1.

setup.com /m:upgrade /InstallWindowsComponents

2.

Import-Module ServerManager
enable-windowsfeature web-wmi

3.

Import-Module ServerManager
