1. First thing we will want to create a new folder where we will want to automatically put all the emails from a specific account.

Open outlook express, right click on the reception box and click on new folder in the sub menu, then name your folderas wished

2. Once your new folder has been created he will be displayed under the reception box in the left hand side
To set up the rule click on tools -> message rules -> mail

3. Then click on new in the next window

4. This step is straight forward: in our case in the first area go down a bit and find the sentence "when the message comes from a specified account" and tick the box
and in the second area look for "move it in the specified folder"

Then click on the 2 blue links in the third area, the first one will ask you to choose the account involved and the second one the folder where you want the emails to go, choose the folder that you have created in the first step.

You can then name that rule if you want and click ok

So from now when you will receive all your email from the specified account they will go straight to the folder that you have created. That is really handy if you want to sepparate you personal email from for example a gmail account or hotmail from you business email from your website.
