If you are using Gmail with Microsoft Outlook, you know how cumbersome it is to keep your Outlook address book in sync with Google Contacts. You add a new contact in Outlook but it won’t magically appear in Gmail. The same is true when you edit a contact’s details in Google Contacts, your Outlook will continue to have the old data.
Would you therefore like to save yourself from this never-ending hassle of maintaining contacts data at two places and have a unified address book.
Sync your Gmail Address Book and Outlook Contacts:
Google offers a free Outlook plugin called Apps Sync to help keep your Outlook Contacts and Google Contacts in sync with each other but probably for business reasons, they have made this utility available only for premier (read 'paying') Google Apps customers - so it does not work with a free Gmail account.
What is Google Apps Sync?
Google Apps Sync for Microsoft Outlook® is a plug-in for Outlook 2003, 2007, or 2010 that lets you use Outlook to manage your Google Apps mail, calendar, and contacts—along with your Outlook notes, tasks, and journal entries. Google Apps Sync seamlessly syncs mail, calendar events, contacts, notes, and tasks between your Google profile in Outlook and your Google Apps account in the cloud. As a result, you can access this same information at any time, from any device where you use Google Apps.
Note: When you install Google Apps Sync, you also have the option to migrate your mail, calendar, contacts, and other data from your old Outlook profile. However, if all you want to do is migrate data (that is, you don't plan to keep working in Outlook afterwards), use Google Apps Migration for Microsoft Outlook® , instead.
