The msexchangeteam blogged how the single-label domain will be able to apply Exchange Server 2007 SP1. There was a change in the prerequisite check file.

Localized versions of this file will be available soon, and we’ll update this blog post when they are available. Do not use the English version of the file if you are running a non-English version of Exchange 2007.

What kind of OCS clients do access the EWS services? In this post of the Communicator team there is a lot information about that.

In the Unified Communications (UC) world 2 types of clients access Exchange 2007 Web Services (EWS) running in Client Access server role (CAS). These two clients are Office Communicator 2007 (OC) and Office Communicator 2007 Phone Edition (OCPE). The Office Live Meeting client, Communicator Web Access and Office Communicator Mobile do not access EWS.

OC uses EWS only if the user is running Outlook 2007 on the desktop with mailbox running on Exchange 2007. OC uses EWS only to access Out Of Facility (OOF) Note and Calendar data. More information about OC can be found here.

OCPE uses AutoDiscover and EWS on the CAS servers. It uses AutoDiscover to locate EWS. OCPE refreshes AutoDiscover information every 24 hours. EWS is used to fetch Outlook Contacts, Voice Mails and Call Logs for the signed in user. OCPE uses EWS only if the signed-in user is enabled for Enterprise Voice and Exchange 2007 UM. If the user is not enabled for Exchange 2007 UM OCPE will not show the tabs for Voice Mails and Call logs.

Michael Affronti has posted about Sync filters and performance in Outlook 2007. He also mentioned a KB with a set of troubleshooting performance tips for Outlook 2007 (http://support.microsoft.com/kb/940226).

Performance is one of the most important characteristics of an application for many of our customers in corporate, small business, and personal environments. Since our application is one that many of you spend a good portion of your day in, the development team here is committed to providing a fast and reliable experience every day when using Outlook. Outlook 2007 is packed with new features, but some of our users are hitting performance issues which negatively impact their day-to-day experience. We are now working even harder for our next release of Office to improve the performance characteristics of Outlook across a number of different features and environments.

Cindy Kwan has posted how to manage the contact list in Ofice Communicator 2007 .

The contact list in Office Communicator (OC) 2007 has a very similar look and feel to lists in other instant messaging clients. However there are some fundamental contact list differences between Office Communicator and other IM clients. I would like take this chance to talk about the structure of the OC contact list and provide some tips for organizing it.

A nice post about Windows Server 2008 and Exchange Server 2007 SP1.

In a previous blog post, we wrote about the various versions of Exchange Server and their support for Windows Server 2008. Now that Windows Server 2008 has released to manufacturing, we wanted to briefly discuss some specific issues that you might encounter as you deploy Windows Server 2008 in your environment, particularly if you’re planning on running Exchange Server 2007 Service Pack 1 (SP1) on Windows Server 2008.

Exchange 2007 SP1 is the only version of Exchange Server that is supported for installation on Windows Server 2008. Now that Windows Server 2008 has RTM’d, Exchange 2007 SP1 is fully supported on Windows Server 2008 in production environments. No other version of Exchange Server, including the released to manufacturing version of Exchange 2007, is supported on Windows Server 2008.

As stated in the blog, Mission Impossible: In-Place Upgrading Microsoft Exchange Server 2007 from Windows Server 2003 to Windows Server 2008, you cannot upgrade the operating system in-place while Exchange 2007 (RTM or SP1) is installed. Thus, the only way to run Exchange 2007 on Windows 2008 is to do a fresh install of Windows 2008 and then install Exchange 2007 SP1.

Most of you might have received the following error:

“The Exchange server address list service failed to respond. This could be because of an address list or email address policy configuration error.”

The research made by the MSExchangeTeam was that only occured if the System Attendant was restarted between 12:00AM, Feb 29 and 12:00AM, March 01.
