The Exchange Calendar Update Tool enables administrators to update multiple user mailboxes and adjust calendars and meetings for daylight savings times.

Important
Before you run the Exchange Calendar Update tool, refer to Microsoft Knowledge Base article 941018, "How to address daylight saving time by using the Exchange Calendar Update Tool," for complete information about potential effects on your IT environment and user base.

After you install the DST updates for Microsoft Windows, all old appointments that occur during the DST change periods will be incorrectly displayed as occurring one hour later. This is true for both recurring and single-instance appointments. These appointments must be updated so that they will be displayed correctly in Outlook, in Outlook Web Access, and in CDO-based applications. Outlook provides a tool that is named the Time Zone Data Update Tool for Microsoft Office Outlook . This tool enables users to update their own calendars.
The Exchange Calendar Update Tool ("the Exchange tool") helps you avoid the challenges difficulties that are faced by administrators in deploying the Outlook tool widely to all users and to make sure that each user runs the Outlook tool correctly.

Exres.dll is Resource DLL of Exchange Server. It acts like "proxy" in communication between Windows Cluster Services and Exchange Services. Windows Cluster service communicates trough Resource Monitor to Exres.dll, and Exres.dll communicates with the Exchange services. This .dll is responsible for reporting failures in the cluster and bringing resources onnline/offline.

If you are brave enough you probably already tried Exchange Server 2007 Service Pack 1 Beta 2. ;-)

So if you want to install Forefront Security for Exchange don`t use RTM version of Forefront Security for Exchange. Microsoft provided special version for Exchange Server 2007 with Service Pack 1 Beta 2.

Overview
Forefront Security for Exchange Server SP1 Beta 2 integrates multiple scan engines from industry-leading security firms into a comprehensive, layered solution, helping protect your Microsoft Exchange Server messaging environments from viruses, worms, spam, and inappropriate content.

This new release provides support for Exchange Server 2007 SP1 and Windows Server 2008, as well as content filtering and manageability enhancements. These enhancements include:

• Seamless support for organizations running IPv6.
• Improved content filtering with installable keyword lists that can be used to eliminate email containing profanity in eleven supported languages.
• Improved integration with Microsoft System Center Operations Manager through new management packs (available in Q4 2007) that allow administrators to proactively monitor the state of their Exchange 2007 protection.
• Increased flexibility for scanning or blocking high compression zip files and RAR archives.

Note: Forefront Security for Exchange users who are running Exchange 2007 RTM and wish to upgrade to Exchange 2007 SP1 must first upgrade to Forefront Security for Exchange SP1.

I`m really busy lately. I have some projects involving Microsoft Exchange Server 2007 Beta 2 (Rapid Deployment Program). But I will talk about that some other time... What I can say for now is that Exchange 2007 really ROCKS (or FYDIBOHF23SPDLT if we take the name from New Exchange Admin Group [H])!

It`s not a new thing but a lot of people never saw it on Windows (but they are familiar with it from Unix or Novell).

So what is Access-based Enumeration?

Windows Server 2003 Access-based Enumeration makes visible only those files or folders that the user has the rights to access. When Access-based Enumeration is enabled, Windows will not display files or folders that the user does not have the rights to access. This download provides a GUI and a CLI that enables this feature.

Exchange 12 uses Active Directory sites as a basis for choosing which servers to communicate with directly. What that means? When running native Exchange 12 organization no additional routing configuration is required. It automatically routes with minimal hops (shortest path between the source and destination). Each Active Directory site is considered a hop.

If no Bridgehead servers whithin site are available due to temporary network outages, mail will be queued at the point of failure. To avoid this kind of failures deploy multiple Exchange 12 Bridgehead servers whitin site. In this configuration mailflow between the Bridgehead and Mailbox servers is automatically load balanced by default. If one Bridhead server is unavailable (due failure or maintance) failover to other Bridgehead servers is automatic by default.
