If you use Google Calendar sync and have upgraded to Microsoft Office 2010 you’ve no doubt discovered that the two don’t work together. Here’s the world’s easiest fix:
- Download this file: GoogleCalendarSync.zip
- Unzip it
- Go to C:Program FilesGoogleGoogle Calendar Sync
- Rename GoogleCalendarSync.exe to OLDGoogleCalendarSync.exe
- Move the new GoogleCalendarSync file to this folder.
- Launch Goggle Calendar Sync.exe
- Fixed.
In the simplest of terms, the latest version of the Sync.exe file reads the version of Microsoft Outlook differently from the way the older version of the same file does. We are simply replacing the latest version of the file with a slightly older one.
Cheers!
UPDATE 17Aug: Google has released an update that should work with the 32 bit version of Outlook 2010

Me 2, same problem and have the same system.

But it seem to sync anyway!!

After copying in the old file, each time it runs, it pops open a window asking that I choose a profile. When I select outlook and click OK it runs, but pops the window open each time. I tried checking the set default block.

I have Outlook 2010 32 bit and Windows 7 64 bit and get the same Could Not Connect Microsoft Outlook error message. Thanks.

At my workplace, I have to have 2 different user accounts on 2 different domains. I have an Outlook calendar (and email and contacts, etc…) on both. Is there any way to synchronize them so that all appointments display on both and an appointment changed/added on one will display on both? I have used the import/export function, but that doesn't remove an appointment which has been deleted.
You would think Microsoft would have an answer, but I can't find it… Any help would be greatly appreciated!

OMG I am a morron! I had never used google calendar before, so I just had to login the first time to activate it! Now it works!

Nice easy fix. Thanks!

many thanks for this, it worked like a charm. I really do appreciate your time and effort in posting this page (and link on the Google help page).

Worked beautifully, thank you! I tried to cheat and copy your EXE straight from the ZIP folder, but found I did actually have to extract the EXE before copying it.
August 4th, 2010 at 6:57 pm
Thank you so much! I upgraded to Outlook 2010 and spent a bit of time researching how to make it work. Your fix worked perfectly! Thanks!

Paul,
I have the same problem you do with the calendar sync btwn Outlook 2010 and Google. It always pops open a window asking that I choose a profile, even when I choose the default option. Did you resolve this?

Any help for those of us with a Mac?
February 16th, 2011 at 1:34 pm
I had uninstalled Calendar sync thinking I could reinstall it, now I cannot get an install no matter what…I keep getting the message "the handle is invalid". Argh. How do I get around this. Please, please help!
February 18th, 2011 at 12:23 pm
Any advice on the equivalent Outlook-Google sync using Outlook 2011 for Mac? or for that matter, syncing Outlook for Mac Tasks to ToodleDo?

For some reason, did not change the error message produced by Calendar Sync, "Could not connect to Microsoft Outlook: error -2147221164". I'm using Win 7 64bit with Microsoft Outlook 2010 32-bit.
April 6th, 2011 at 9:59 pm
I'm with Zamp. I did as instructed and nothing is different. I still get "Could not connect to Microsoft Outlook: error -2147221164"
(sigh)

This fixes the problem with the new version of Calendar Sync (on PC's)
1) install autoit from http://www.autoitscript.com/
2) paste the text below into a notepad window & save it as outlookProfile.au3 (change the Save As Type dropdown to All Files)
3) double click the file.
4)You may want to add a shortcut to your startup so you don't have to run it each reboot. To make it run at startup you want to copy
a shortcut of the file to the Startup folder on the Start Menu. C:Documents and SettingsAll UsersStart MenuProgramsStartup
While 1
WinWait("Choose Profile")
if (WinActivate("Choose Profile")) Then
ControlClick("Choose Profile", "OK", "Button2")
endif
WEnd

Hi!
I have tried above, but can not get it to work for my error message. The message says:
" Could not connect to Microsoft Outlook: error -2147319779. Please see our…".
I am running Win7 with Outlook 2007 (complete Office). The reason is I got an new computer, but could not let go of Outlook 2007 due to the Categories functionality that is not the same in 2010.
If anyone can help I would be thrilled.

Thank you for another informative web site. Where else could I get that type of info written in such a perfect way? I have a project that I’m just now working on, and I have been on the look out for such info.

I have at least one problem with Calendar Sync. I have uninstalled and reinstalled Outlook and Calendar sync. With Outlook ON I get an error 2146959355 (I have tried the suggested fix of removing folder 9.3 in the Registry). with Outlook OFF I get TWO identical messages "No Microsoft Outlook profiles have been created. In Windows …. go To Mail in control panel and add". I have tried adding a new profile and also removing and re-configuring the existing Outlook profile. Behind these two messages, I also get an error 2006. Outlook seems OK for email in and out. I don't know what to try and would appreciate any advice. Thanks

I have the exact same situation as you David…2 different domains at work and 2 calendars that I want to share / synchronize. Did you ever find a way to do this?
September 20th, 2012 at 1:13 pm
The exe by itself does not work for me can you also supply the DLL's as well to match
December 4th, 2012 at 11:55 am
Very Helpful! I wasted the past several hours trying to figure this out…. Google, why are you not on top of this!
