Problem

When you’re building (or already) have a active/passive Exchange 2007 cluster and you try to move the cluster to the other node, it’s possible you receive an error like this :

The installation on node ‘NODE’ is inconsistent. ConfiguredVersion=, UnpackedVersion=8.2.176.2. An upgrade might not have completed successfully.

As the error already explains, there is a version problem. To understand this problem you need to know a little bit about the installation steps Exchange does while installing. Read more »

The Microsoft Exchange Team announced the release for Service Pack 2. It’s expected in Q3 of 2009.

This Service Pack will be required for transitioning to Exchange 2010.

When you want to adjust the Maximum Attachement Size in Exchange 2007, you can use this script to check where the size limits are set.

The only Message Size limit that is not set through Powershell, is the one for Outlook Web Access. This is done through the web.config file on the Client Access Server.

• First make a backup of the web.config file (default location c:\Program Files\Microsoft\ExchangeServer\ClientAccess\Owa).
• Open the file with Notepad
• Change the line <httpRuntime maxRequestLength=”30000″ />
  Where 30000 is the maximum message size (in kilobytes)
• Save the file (nothing else needs to be done)

When you want to upgrade to Exchange 2007 SP1, from the RTM version, follow these steps :

Installation Steps

• Install Net 2.0 SP1 on your Exchange 2007 Servers
• Reboot the servers
• Prepare the Schema: Read more »

I was looking for a way to create a custom signature for all users within our company. Unfortunatly with Exchange 2007 there is no way to achieve this, besides adding a Disclaimer with a transport rule.

After searching I came accross a login script with wich you can create an automated signature based on Active Directory information.

Maybey a nice addition in Exchange 2007 SP2??
