De acordo com informação publicada no blog da equipa de Exchange da Microsoft, estas são as principais correcções:

1. KB 969911 - This is bug likely to affect customers who have deployed the Messaging Records Management feature and have specified a storage limit for a managed folder. After a move mailbox, the property which marks the folders as managed is not preserved.
2. KB 968621 - Store stops responding under certain conditions when scheduled backup is canceled and online maintenance is in progress.
3. KB 945877 - Performance improvements to eseutil when it verifies the checksum of transaction logs.
4. Support for Windows Server 2008 R2 Domain Controllers in the environment (Note: Exchange Server 2007 itself is not supported to be installed on a Windows Server 2008 R2 system.
5. KB 968715 - This bug is likely to affect customers who have deployed CAS-CAS proxying. When a user selects This is a public or shared computer or This is a private computer on the Outlook Web Access logon page, this value is not maintained  between the CAS servers when the request is proxied. This bug will most likely affect customers with Internet facing CAS sites which proxy the requests to internal sites. Now the bug was that we defaulted to private access irrespective of the option selected by the user. Outlook Web Access has the following features which allow the administrator to control access of users depending on the logon type.:
   • Public and Private Computer File Access
   • WebReady Document Viewing

After deploying this rollup, the logon type will now be correctly maintained between CAS servers if the request is proxied.
Administrators should watch out for scenarios where they have configured different behavior based on the logon type and required users to select the private computer option to access files, but users were able to access files without selecting the private computer option due to this bug. These users will now be unable to do so because we fixed the bug.

Como é habitual, usei as minhas máquinas virtuais como cobaias e o resultado foi bastante satisfatório!
