Contacts Sync is free software that syncs Outlook contacts with Google Contacts. From there, an Android device can sync automatically with Google Contacts to complete an Outlook to Android sync. Outlook 2003-2010 are supported. There is an automatic sync feature, so you can set it and forget it.
When I tested Contacts Sync, it installed easily and synced flawlessly. While this software is free, its functionality leaves some things to be desired. It syncs only one way in the direction of your choice, but not bidirectionally. It does not sync contact notes or contact pictures. While there is no listed documentation, installation or user's guide, I must admit the ease of installation and intuitive setup did not require additional support. If you do need help, there is an email address and contact form at their site available for support. There is also a small FAQ to help with a few questions. When I wrote to find out more about their product, the vendor responded very quickly and politely.
