There are many tutorials out there but they are all too complicated or/and give you paid, complicated tools to do the job.

Both tools on this post are free, will sit on your tray and won’t bother you, while maintaining your contacts and calendar synced. I’m gonna show you the easiest way to do it.

Google Calendar Sync

google calendar

Download page:
(Direct link to download)


  1. Read through the Google Calendar Sync Terms of Service, and click I Agree.
  2. Follow through the Installation Options and click Install to finish the set-up process.
  3. Once Google Calendar Sync is installed on your computer, the Google Calendar Sync Settings window will appear:

Google Calendar SyncPrint

Just enter your email/password and click Save. If you don’t want to sync back to Google Calendar choose “1 way: Google Calendar to Microsoft Outlook”

You are now syncing Google Calendar with Outlook!

Go Contact Sync

As the name says this is the plugin that’s gonna sync your Gmail Contacts. It supports contact categories and contact photos so your contacts will look exactly the same.

  1. Follow the setup instructions..
  2. After installed, choose Start > All Programs > GO Contact Sync

GO Contact Sync Configuration

Just enter your email/password, make sure Sync Profile is not empty (enter any text, the program doesn’t allow it to be empty) and click Sync. Also check “Run program at startup .

You may be prompted by Outlook that a program is trying to access it. Grant permission to it for 5 minutes.

You are now syncing Gmail Contacts with Outlook!


Because Go Contact is still in beta you may some notices from the program that an error has ocurred. I found that a restart to the program solves it. I don’t know what the error means but a future release should correct the bug.

Also you are not limited to Outlook. With your Outlook synced you can keep your mobile also synced without spending money; I keep my Nokia N70 synced by bluetooth (maybe a future blog post). I just tell Nokia Suite to sync Outlook with my Nokia everytime its in range and now I have Google Calendar and Gmail Contacts on my pocket 24/7.


If you have any questions or problems just reply on the comments.

    Lonnie, I had that problem also. I was using the “Merge Prompt” option to be safe. I believe the problem was that Google Contacts were empty, so there was never a match to merge. When I selected “Outlook To Google Only”, it proceeded to copy the Outlook contacts to Google.

    Try using “Outlook To Google Only” to start. See if that does not make a difference.

    A lot of people seem to be having Index errors. I would suggest that the first place to start is to run the ScanPST tool to be sure that the Outlook data file is not broken. Go to this article from Microsoft on locating and running the tool:

    Then see if Go Contact Sync works properly.

    I've installed GO Contact Sync twice. I have Outlook 2007. At first, only 43 contacts synced, and then it failed. Something about Execution of request failed …

    I restarted serveral times. I still can only get 223 of 251 contacts synced. Needs work.

    google (gmail calendar sync) causes my outlook to continuously restart everytime it trys to sync. what would cause that. so consequently they never get synced

  • edwardally

    my error is
    Authorization Required!!!
    What is this?

  • Dennis

    What a great tool. I have been looking for years for this!

  • Yes

    Doesn't sync details like birthday…. Which makes it kind useless for my objective: full sync.

    I successful download Go Contact to my PC and synced my contacts with gmail, but for some reason a contact I added in the pc was not added to google when I was done. What am I doing wrong?

  • Andy

    I fixed this by deleting all contacts with duplicate email addresses. I had a few contacts with different variations (eg “Joe Blogs” and “Blogs, Joe”) which had the same email addresses. Once I dleted the duplicates, it worked.


  • Andy

    I got it to work with 2007 by running both outlook and calendar sync as administrator. Not ideal, but it worked. Another thing I found is that if you use Microsoft “click to run” or App-V virtualised software (eg you download a trial then register it), it doesn’t work. My wife had office 2010 installed this way. I completely uninstalled office and click to run, then reinstalled from the DVD and it now works.

     Hi, when I use Go contact  the leading “0″ (zero) on my phone numbers in Outlook is lost on syncing to gmail – any tips to fix this?
