The Compatibility mode of Windows is a great feature to make usage of legacy programs that have not been or will never bee updated to the latest Windows version. Since Windows 7 even mode modes (including Windows Server) back to Windows 95 are supported. The number of supported versions might vary depending on the Windows 7 version you use, however, the Vista and XP mode should always be available.

    I hoping this would solve my problem but it may be beyond your scope. I have the SAmsung Epic phone (new) and so I switched to Google calendar etc. Outlook and Google calendar are syncing. If I input something on my phone in the calendar, it does not sync with Google calendar. Any ideas?

    Thank you, fixed my sync problem on win7 ultimate 64bit, I was starting to get annoyed that I had to use lightning and thunderbird to sync.

    Thank you! Now do you know if running in compatibility mode also works for Win 7 64 bit/Outlook 2010?

      Kathryn, I meanwhile switched to Outlook 2010. Unfortunately, it seems that there is a new issue. This might be caused by the fact, that the plug-in does not play well with the new Outlook version. I might write about this once I figured out.

      Hi Charles, unfortunately there are no news regarding Outlook 2010. The Google software just provides error numbers I cannot find any information for. That’s very unfortunate. Considering the time I had to spend in getting the Google tools running, I meanwhile switched entirely to as online solution.

    @Maureen – my HTC Desire is doing the same thing. I have to
    manually refresh the calendar then events I added on my phone show
    up. @Andreas – I tried the above solution without success. My sync
    does not give the same error code, it says could not connect to
    Microsoft Outlook error 2146959355 and to see the error centre
    (which of course tells me nothing). I have spent several hours
    working on this to no end. To be honest I cannot seem to figure out
    whether I am running Office 2007 in 32 or 64 bit. My operating
    system is Windows 7 (64 bit). And I am also trying to set up a
    Windows 7 (starter version) on a netbook with Outlook 2010 and it
    won’t sync either. I can sync the private url but not the public
    one. Of course I cannot edit the private one it is just a
    snapshot… so frustrated.

    the images associated with this post are missing. i see from your July 2011 post that you’ve migrated to WordPress. i guess the images didn’t make the trip? i had to search your blog for this article as my old link was 404. i think yours is one of the best descriptions of the workaround for Google Calendar Sync on Win 7, i refer to it whenever i’m re-installing. thanks for posting, sure hope you can find those images.
