We have released Update Rollup 8 for Exchange Server 2007 Service Pack 1 (KB 968012) to the download center. The release of the rollup via Microsoft Update will happen on May 26.
As in the previous rollups, we have done a mix of product improvements (aka Critical Design Change Requests) and bug fixes. A few key ones which I would like to call out are as follows:
KB 969690 - We have fixed the bug introduced in Update Rollup 7 which caused the sender of the Delivery Status Notification (DSN) to be unresolved.
Disable kernel mode authentication in Windows Server 2008 for CAS servers - As documented here, it was required to manually take the additional step to configure the CAS servers running Windows Server 2008 to disable kernel mode authentication. Starting this rollup, the installer will configure this for you.
X-Header promotion to named properties- Change to the way X-headers are promoted to named properties. More on this in Jason Nelson's blog post Named Properties, X-Headers, and You.
KB 961606 - We have fixed a bug where Outlook Web Access (OWA) users may find that the font size of plain text messages is extremely small on third-party Web browsers.
KB 968012 has more details about this release and a complete list of all fixes included in this rollup.
As a follow up to the Exchange Server 2007 Service Pack 2 (SP2) announcement, all fixes in this Update rollup and the previous ones we have released for Exchange Server 2007 will be included with Exchange Server 2007 SP2. We will have a blog post soon which covers:
When update rollups can be expected for Exchange 2007 SP2.
As always, the Exchange Software Updates forum is available to provide help if you encounter issues in the updates we release for Exchange. We have staffed the forums with engineers monitoring the forum ready to assist you and request you to utilize that mode instead of asking for help via comments on this blog.
