Exchange 2007: Preparing the server

Recently I prepared a server to install Exchange 2007 on Windows 2008 R2. Instead of manually installing all the prerequisites, I downloaded the XML files created by the Exchange Server Team and applied them to the machine. This saved me a considerable amount of time and the cool thing is that there’s one for each Exchange role. Another sweet feature of the XML templates is that it would check if the Windows Role or Feature is already installed and it would automatically skip the Role or Feature if it is already present. There are 6 XML templates to prepare an Exchange server.

These XML files are applied by using ServerManagerCMD -InstallPath <Path>\Exchange-Base.xml

Exchange 2007 Troubleshooting: Don’t know where to start?

Exchange 2007 suppresses a host of rich information from appearing in the Event Viewer. When troubleshooting a particular Exchange 2007 component, increasing the EventLogLevel for the particular component can save a lot of time and heartbreak. To view the currently set EventLogLevel for any Exchange 2007 component, launch Exchange Shell and type the following command:

Exchange 2007 "Legacy Mailbox" after migration from Exchange 200x

It’s been a long week but I thought I had to post on little migration issues that I am currently seeing. OWA seems to be full of cryptic error messages. With that said, If you read the errors very carefully, especially the parts highlighted in red in the error message sample below, you should get a pretty good idea why the request is failing. Here’s one I saw this week:
 
 
SCENARIO:
Exchange 2007 was installed into an existing Exchange 2000 organization. All the mailboxes are being moved manually through the EMC 2007. However, after migrating some users, they attempt to login to OWA and they get the error below:

Fix CCR replication using Update-StorageGroupCopy

During a recent migration, the log files on the Exchange 2007 server kept filling up too quickly. What engineers typically do not plan for during an Exchange 2007 migration are the amount of log files generated during the migration.

I’ve been caught by this issue before. So what’s the cure? Plain and simple, run a full backup of the particular storage group to flush the logs.

Unfortunately, this isn’t always possible since the storage group fails to continue replicating and the database dismounts because the log drive is full.

This means that you’ll have to delete a few log files. In order to establish which log files are required for the database to come up and function properly, follow the instructions in this KB:
