Earlier today, Microsoft released Update Rollup 4 for Exchange 2010 Service Pack 2.

The update includes a new feature as well as an important update that I would like to call out:

  • Calendar & Task (items) now support Retention Tags. Before this was not the case, as tags could only be applied to mail items/folders. Although tags for Calendar/Task (items) can only be configured by an Administrator (PowerShell), they will at least prove useful for companies that (heavily) rely on the use of Retention Policies to keep their mailboxes clean. If you are already using Retention Policies or are looking to implement them, there are some caveats to look out for when installing UR4. These items have been well described by Ross Smith IV in his article. I suggest you take a look at them.
  • a fix for a vulnerability in WebReady Document viewing that was recently reported. When the vulnerability was first reported, you were advised to temporarily disable this feature using the following command:
    [sourcecode language=”powershell”]Get-OwaVirtualdirectory | ?{$_.OwaVersion –eq ‘Exchange2007’ –or $_.OwaVersion –eq ‘Exchange2010’} | Set-OwaVirtualdirectory –WebReadyDocumentViewingOnPublicComputersEnabled:$False –WebReadyDocumentViewingOnPrivateComputersEnabled:$False[/sourcecode]

    After installing UR, you can safely re-enable the feature by using the following command:
    [sourcecode language=”powershell”]Get-OwaVirtualdirectory | ?{$_.OwaVersion –eq ‘Exchange2007’ –or $_.OwaVersion –eq ‘Exchange2010’} | Set-OwaVirtualdirectory –WebReadyDocumentViewingOnPublicComputersEnabled:$True –WebReadyDocumentViewingOnPrivateComputersEnabled:$True[/sourcecode]
