Prerequisite is that you download and install the 1&1 MXConnector before you begin.
Double-check the rest of the information as it should have been auto-completed for you. Change the Drive Letter if you wish to assign the 1&1 InfoStore another drive letter. If the Restore at startup check box is checked, the program will automatically log you in and assign the same drive letter to the 1&1 InfoStore when the computer starts up.
In My Computer, you should see the 1&1 InfoStore mapped as the drive letter you have chosen.
