Changing the Queue Database path in Exchange Server 2007

Share this:

Hello folks,

 Today, we are going to visualize how to change the Queue Database in Exchange Server 2007. That feature is one of the innovations of Exchange Server 2007 which uses the ESE engine to control the queue. The queue database is found only in two server roles: Hub and Edge Transport. Let’s see how to change it:

The default path of the Queue database and transaction log is “C:Program FilesMicrosoftExchange ServerTransportRolesdataQueue”. To change this settings, we should open the file EdgeTransport.exe.config in this file we have to parameters:

  • QueueDatabasePath: Database path (mail.que and trn.chk files)
  • QueueDatabaseLoggingPath: transaction logs path (*.log and *.jrs files)

Now, let’s change both parameters for the c:Database folder, as shown in the figure below.

After changing the config file, we have to methods do accomplish our queue database moving process:

Moving the current database

  1. Click on Start / Run and type services.msc  click OK
  2. Stop the service called Microsoft Exchange Transport
  3. Move the database files(mail.que and trn.chk) from original location to the new place
  4. Move the transactions log files (*.log and *.jrs) from original location to the new place 
  5. Start the Microsoft Exchange Transport service

Creating a new queue database

  1. Click on Start / Run and type services.msc  click OK
  2. Restart the the Microsoft Exchange Transport service

In both cases the result will be the same, the new database will be changed for the directory specified in the .config file.
