Microsoft Exchange Server 2007 Service Pack 3 Help

Exchange Server 2007 SP3


Microsoft released Service Pack 3 for Exchange Server 2007. SP3 raises Exchange Server 2007 version number to 8.3.83.6.

Major change in this Service Pack is that it enables you to install Exchange Server 2007 on Windows Server 2008 R2. It will also allow you to install the Exchange 2007 Management Tools on Windows 7.

Another nice addition is the new password reset tool for OWA users; no more fiddling around with the IISADMPWD in IIS on Client Access Servers. Enabling the password reset rool just requires creating or setting the following registry key on CAS servers (its disabled by default):

HKLM\SYSTEM\CurrentControlSet\Services\MSExchange OWA\ChangeExpiredPasswordEnabledValue (REG_DWORD) = 1

More information on the new password reset tool can be found on TechNet here.

The Exchange Server 2007 SP3 Release Notes are available on TechNet here; the What’s New in Exchange Server 2007 SP3 topic is located here.

Note that the download contains the full set of binaries; you can use it to upgrade existing installations but it can also be used to deploy new Exchange 2007 SP3 installations. Note that upgrading or installing Exchange 2007 SP3 on a system which is going to be or has been upgraded from Windows Server 2008 to Windows Server 2008 R2 in any way is unsupported.

You can download the x64 or x86 version of SP3 from here. The updated Unified Messaging Language Packs can be found here.

The Exchange versions, builds and dates table has been updated accordingly and can be found here.

Exchange Mailbox Role Calculator updates


Updates? Yes, updates. Both the Exchange 2007 Mailbox Role Calculator as well as the Exchange 2010 Mailbox Role Calculator have been updated.

The Exchange 2010 Mailbox Role Calculator has been updated to version 7.7 (was 6.3, so major update). This version includes the following enhancements:

  • 32-core support;
  • Fourth mailbox tier in the calculator;
  • Two new columns to the primary data center “Active Database Configuration / DAG” table to expose the total number of databases activated in each site after server failure events. This change was added to expose cross-site database fail-over events;
  • Option to activation block secondary data center mailbox servers that host HA database copies. This allows you to design a solution where you can activate the secondary data center in the event of a primary data center failure mode, or choose to activate a copy in the secondary data center manually, but prohibits Active Manager from automatically activating a copy in the secondary data center;
  • Modified IOPS Multiplication Factor calculations from “Base + (Base * Multiplier)” to “Base * Multiplier” to accommodate some 3rd party factors (so now you should use 1.5 instead of 0.5).

Besides enhancements, the updated Exchange 2010 Mailbox Role Calculator also contains some bug fixes which are described in the changeblog. You can download the updated calculator here. Usage instructions can be found here.

Regarding the Exchange 2007 Mailbox Role Calculator, it has been updated to version 17.5 (was 17.3). It contains some minor fixes. The Exchange 2007 Mailbox Role Calculator can be found here (changeblog, instructions).

Exchange 2007 Mailbox Role Calculator 17.3


Exchange 2007? Yes! With all this Exchange 2010 coverage one might forget about Exchange 2007, but not the Exchange team who updated the Exchange 2007 Mailbox Server Role Storage Requirements Calculator to version 17.3.

The major change in this version compared to version 16.9 (released April, 2009!) is a change in the IOPS calculation. This change is to based on the BlackBerry Enterprise Server for Microsoft Exchange 2007 Performance Benchmarking Guide which simplifies the IOPS calculation in combination with 3rd party software.

The update also contains some bug fixes which are contained in the release notes. You can download the calculator here; usage instructions can be found here.

MAPI Client and Collaboration Data Objects 1.2.1


The MAPI and CDO libraries, still required by some applications or scripts talking to Exchange, have been updated.

The libaries are meant to unwind the application and storage layers, making applications and code using these libraries independent of the underlying Exchange or Outlook version. It also enables certain applications/scripts to run remotely (mostly apps/scripts from the pre-PowerShell era). Only problem you can encounter is when applications/scripts make use of certain functionality only to be found in certain Exchange/Outlook versions, requiring specific MAPI or CDO library versions.

These libraries may be required by certain 3rd party applications, scripts, etc. that need to interface with Exchange, e.g. Blackberry Enterprise Server, the Transporter Suite (for Notes-Exchange co-existence/interoperability), Quest Exchange tools, etc. etc.

Note that MapiCDO release follows Exchange Server 2003’s lifecycle and it is recommended you upgrade your application or port your application/script to and start leveraging new Exchange interfaces, e.g. Exchange Web Services, Outlook Object Model or the Outlook MAPI Client Library.

ExchangeMapiCDO 1.2.1  version 6.5.8165.0 can be download here.
