What version of Outlook are you using?
I've found several references to this error which might help.
If you have an older version of Outlook, this might help: See if there's something called TaskPad in Page Setup. If so, try unchecking it.
If that's not something that will work, try disabling the addins by going to Tools > Options > Other tab > Advanced Options
Click on the Addin Manager button. Remove any reference to Google desktop. (or any other addin not native to Outlook) Click ok.
Do the same for the Com-Add-ins button.
Microsoft also has a patch, but I'm not sure it applies in your case and it's only for the specific symptoms it describes.http://support.microsoft.com/kb/275186
Did any of this help?
