I have recently had problems with outlook 2010 so I installed MS Configuration Analyzer Tool 2.0. It states that Collaboration Data Objects (CDO) 1.2.1 needs to be uninstalled but I can't find the program or file on the computer. Where should I look? I am running windows 7 bit 64 but office 2010 is bit 32Judy

I seem to remember that it is offered as an optional component of the Outlook installation. If your Outlook was installed as part of an Office installation (it often is, but can also be installed separately), run the Office installer, choose to modify the installation, and see if you can see CDO listed as one of the Outlook components. If you can, remove it that way, by unchecking it. Having said all that, CDO doesn't usually cause a problem, so you may find that removing it doesn't fix your original problem.Mobile OWA For Smartphone www.leederbyshire.com email a@t leederbyshire d.0.t c.0.m
